A MINI R56 water pipe replacement may be necessary if you are finding coolant under the vehicle near the rear of the engine.

As we have discussed in our other MINI R56 articles, the BMW/Peugeot Prince engine found in all 2006-2013 Cooper and Cooper S vehicles has had its fair share of issues. One of the more irritating problems that has haunted MINI R56 owners is failure of the coolant system's water pipe.
The MINI R56 water pipe is a rigid plastic conduit that runs laterally across the rear of the engine underneath the intake manifold. Its sole function is to deliver coolant from the water pump to the thermostat so it can be channeled into the cylinder head. Due to the compact transverse design of the Prince engine, the water pump and thermostat ended up on opposite sides of the engine compartment - the plastic water pipe completes the connection between the two.
Like all plastic parts in the engine compartment, age and the brutal heat conditions take their toll on the MINI R56 water pipe. Often the water pipe cracks inside the water pump fitting causing its o-ring to leak. In extreme circumstances, the body of the water pipe can fracture causing a complete loss of coolant. A MINI R56 water pipe replacement should be immediately performed at the first signs of failure.
Classic signs that your MINI R56 has a failing water pipe are puddles of coolant on the ground under the rear of the engine and constantly having to "top off" your coolant expansion tank.

Accessing the MINI R56 water pipe

The correct way to extract and reinstall the MINI R56 water pipe is to remove both the thermostat and the intake manifold from the vehicle. The intake manifold must be removed in order to properly install the new water pipe. The water pipe must be grasped with both hands during installation to ensure it is properly seated in the water pump. This is not feasible unless the intake manifold is removed.
As the MINI R56 water pipe becomes old and brittle, it also has a reputation of breaking off inside the water pump while being removed. Trying to extract these bits of plastic and rubber o-ring from the water pump is next to impossible without removing the intake manifold (or the water pump itself).
Removing the intake manifold shouldn't be considered a deterrent to doing the repair but rather an excellent opportunity to replace manifold and throttle body gaskets, the thermostat, as well as service your MINI's fuel injectors. Now is a great time to get all of these high-maintenance items done while you have the thermostat and intake manifold removed from the engine.

Section 1 - Removing the Intake Manifold
As discussed at the beginning of this article, the correct way to perform a MINI R56 water pipe replacement is to remove the intake manifold. The water pipe must be grasped with both hands during reassembly to make sure it is pressed inside the water pump correctly - this is simply not possible with the intake manifold installed. We urge our readers to not consider removing the intake manifold as an inconvenience, but rather as an excellent opportunity to service other high maintenance parts like the intake manifold gaskets, throttle body gasket and fuel injectors.
  1. Using a 10mm socket wrench, remove the negative terminal from the battery and wrap it in a rag to avoid it from inadvertently touching the terminal.MINI R56 intake manifold - Disconnect the battery before starting this repair.MINI R56 water pipe replacement - remove negative terminal lead from the battery with a 10mm socket wrench.
  2. In order to get to the MINI R56 intake manifold, some engine parts need to be cleared out of the way. Start by pinching in the plastic tabs and removing the intake manifold tube from the intake manifold pre-box.MINI R56 water pipe replacement - Remove the intake manifold tube from the pre-box.MINI R56 water pipe replacement - Pull the intake manifold tube free from the pre-box.
  3. Using a 10mm socket wrench, remove the bolt anchoring the intake manifold pre-box to the engine. Grasp the pre-box and pull free from the intake muffler.MINI R56 water pipe replacement - Unbolt the intake manifold pre-box from the engine. Remove the pre-box from the engine compartment.
  4. Disconnect the mass air flow (MAF) sensor. This connection can be a little tricky...the release is under the plug. Try using a metal pick to depress the release then pull the plug free.MINI R56 water pipe replacement - Unclip the MAF sensor connection. Its a little tricky...use a metal pick to release it if necessary. Pull the MAF connector free from the sensor.
  5. Use a 10mm socket wrench to loosen the bolt anchoring the intake muffler to the engine.MINI R56 water pipe replacement - Loosen the intake muffler anchor bolt.

  8. Grasp the base of the intake muffler and pull it loose from the body of the car. It is held in place by two rubber grommets.MINI R56 water pipe replacement - Remove the intake muffler base from the vehicle.
  9. The next step is to remove the fuel rail from the back of the engine. The fuel rail must be removed to access the upper intake manifold mounting bolts. MINI R56 water pipe replacement - Locate the fuel rail on the back of the engine.
  10. Before disconnecting the fuel rail, it is good practice to release any fuel pressure that might be left in the system. This is done by simply depressing the Schrader valve located on the end of the rail. First, locate the Schrader valve and remove its protective cap.MINI R56 water pipe replacement - Remove the protective cap off of the fuel rail schrader valve
  11. Lay a rag under the Schrader valve to catch any fuel that may be ejected when releasing the pressure. Press the valve stem in with a small screwdriver or metal pick to release the pressure in the fuel rail (it's like releasing the pressure from a tire valve). Replace the cap when you are finished.MINI R56 water pipe replacement - Release the pressure in the fuel rail by depressing the Schrader valve
  12. Remove the fuel line from the end of the fuel rail by retracting the black lock ring and pulling it free as shown below. Have a rag ready to catch any fuel that may spill out.MINI R56 water pipe replacement - Retract the black collar to release the fuel line from the fuel rail. Pull the fuel line off of the fuel rail.
  13. The next step requires removing the two T30 bolts anchoring the fuel rail to the cylinder head. The two bolts are difficult to see since they are behind the engine...use an inspection mirror to locate them if necessary.MINI R56 water pipe replacement - Remove the two torx bolts anchoring the fuel rail to the engine. Fuel rail torx screw
  14. When you have removed the two T30 mounting bolts, grasp the fuel rail with both hands and pull the injectors free from the cylinder head. You may have to gently rock it back and forth while pulling to get the injectors to release.MINI R56 water pipe replacement - Pull the fuel injectors from the cylinder head.
  15. Unclip the wiring harness from the back of the valve cover and gently lay the fuel rail and injectors safely out of the way. Now is a great time to replace your fuel injectors...it is just a couple more easy steps. If you are interested in replacing them, please read our article MINI R56 Fuel Injector Replacement – 2006-2013 Cooper.Unclip the injector wiring harness from the back of the valve cover. MINI R56 water pipe replacement- Pull the fuel rail out and away from the engine and gently lay top the side out of the way.
  16. Use a metal pick to raise the plastic lock on the intake (rear) VANOS solenoid sensor. Pull the sensor plug out of the solenoid and unclip it from the valve cover.MINI R56 water pipe replacement - Remove the electrical connection from the rear intake VANOS solenoid.MINI R56 water pipe replacement - Remove the rear inatke VANOS solenoid connection.

  18. Disconnect the crankcase breather hose from the valve cover by squeezing the plastic locking ring and pulling it free.MINI R56 water pipe replacement - Disconnect the crankcase breather hose from the valve coverDisconnect the crankcase breather hose.
  19. Disconnect the Valvetronic motor sensor on the back of the engine.MINI R56 water pipe replacement - Disconnect the Valvetronic motor.
  20. Reaching down underneath the Valvetronic motor, use a metal pick to raise the plastic locking tab on the differential pressure sensor plug. Pull the plug free of the sensor.MINI R56 water pipe replacement - Disconnect the differential pressure sensor.
  21. Next, the throttle body must be removed from the intake manifold. There is unfortunately not enough clearance to remove and then properly reinstall and torque the far right manifold mounting nut with the throttle body attached. There are three torx screws anchoring the throttle body to the intake manifold. Note that one of the screws is hidden behind the throttle body opening and is difficult to find.MINI R56 water pipe replacement - Throttle body and its mounting screw locations.
  22. Start by removing the 10mm bolt anchoring the plastic wiring harness bracket to the engine mount. This wiring harness bracket blocks access to the lower throttle body screw. Removing the 10mm bolt will loosen it enough so it can be pushed out of the way.MINI R56 water pipe replacement - Loosen the plastic wiring harness bracket below the throttle body.Push the plastic wiring harness bracket out of the way.
  23. Remove all three screws using a T30 torx bit.MINI R56 water pipe replacement - Remove the three throttle body screws.
  24. Grasp the throttle body, pull it loose and disconnect its electrical connection. Remove the throttle body from the vehicle. You now have clear access to the intake manifold and its mounting bolts.Remove the throttle body from the vehicle.
  25. There are six anchor points securing the intake manifold to the engine head; five upper mounting nuts and one lower mounting bolt (see diagram below). Many mechanics struggle, and hence get frustrated, trying to find and remove the lower bolt. To address this, we have created easy to follow instructions that will help you quickly find and remove the lower bolt with relative ease.Intake manifold mounting diagram
  26. Start with the five upper mounting nuts. Remove all them with a 13mm socket wrench.MINI R56 water pipe replacement - Remove the five upper intake manifold mounting nuts.
  27. Next, the sixth lower mounting bolt must be removed. This is unfortunately a slightly difficult process...the bolt is tucked away at the bottom of the intake manifold behind the fuel line vent valve and is often a challenge to locate. Compounding the issue is there are other bolts in the vicinity that can make it confusing as to which one needs to be removed. If you use patience and exactly follow our steps, you will be able to successfully remove the bolt.
  28. First, the fuel line vent valve must be removed from the back of the intake manifold. The reason why the fuel line vent valve must be removed is because the lower intake manifold mounting bolt is hidden behind it. Use an inspection mirror and the following images to locate the fuel line vent valve mounting bracket and the bolt anchoring it to the back of the intake manifold.MINI R56 water pipe replacement - Fuel line vent valve locationUse an inspection mirror to find the fuel vent valve bracket mounting boltMINI R56 water pipe replacement - Fuel line vent valve
  29. Use a 10mm socket wrench to remove the fuel line vent valve bracket bolt. MINI R56 water pipe replacement - Remove the 10mm mounting bracket bolt.Remove the bracket from the intake manifold
  30. Squeeze the plastic connector on the vent valve vacuum line where it connects to the intake manifold. Disconnect the vacuum line from the intake manifold and carefully stow out of the way.MINI R56 water pipe replacement - Disconnect the fuel line vent valve vacuum line from intake manifold.MINI R56 water pipe replacement - Stow the valve and vacuum line out of the way.
  31. You now have clear access to the lower intake manifold mounting bolt. Use an inspection mirror to locate it...it is located slightly to the right of the intake's centerline at the very bottom. We like to put an automotive work light behind the engine to help find it (see images below).MINI R56 water pipe replacement - Lowe intake manifold mounting bolt locationUse a shop light and inspection mirror to find the lower mounting bolt.MINI R56 water pipe replacement - Lower intake manifold mounting bolt
  32. Use a 9mm socket wrench to remove the lower intake manifold mounting bolt.
  33. The intake manifold is now free. Gently push it backwards off of the cylinder head exposing the gaskets.Pull the intake manifold back from the engine head.
 
Section 2 - Removing the Thermostat
As discussed at the beginning of this article, the thermostat must now be removed in order to finish removing the water pipe. The reason is that the left side of the water pipe is connected to a thermostat coolant inlet...there is, unfortunately, no way to separate and remove the water pipe while the thermostat is still mounted to the engine.
  1. It is very difficult to remove the intake manifold tube from the front bumper. We strongly suggest just bungee cording it out of the way instead of attempting to remove it.Bungee cord the intake pipe out of the work area
  2. Next, the engine wiring harness will need to be cleared out so the thermostat can be accessed. Start by disconnecting the intake and exhaust camshaft sensors on the left side of the valve cover. Mini R56 water pipe replacement - Disconnect the intake camshaft sensor Mini R56 water pipe replacement - Disconnect the exhaust camshaft sensor
  3. We highly recommend marking all of your connections with high visibility tape to aid during reassembly.Mark all connections with high visibility tape

  25. Finally, the thermostat needs to be released from the water pipe. The water pipe runs from the water pump on the right side of the engine to the back of the thermostat. Using a metal pick (or your fingers), pull the metal locking clip up to release the pipe. Release the metal locking clip on the rear water pipe.
  26. The thermostat can now be unbolted from the engine and removed from the vehicle. Use a 10mm socket wrench to remove the three thermostat mounting bolts. We suggest using an extension and low profile socket to reach the rear mounting bolt.Mini R56 water pipe replacement - Remove the thermostat mounting boltsMini R56 water pipe replacement - Remove the thermostat mounting bolts
  27. Grasp the thermostat with both hands and remove from the engine. The thermostat can often be difficult to release from the water pipe.

Section 3 - Removing and Replacing the MINI R56 Water Pipe
Now that the intake manifold and thermostat have been removed from the engine, replacing the water pipe is fairly easy. Remember to always double-check the water pump to make sure there are no broken fragments of plastic or o-ring left from the water pipe. Also, it is very important to note that you should only use a small amount of liquid dish detergent when lubricating the water pipe o-ring for insertion into the water pump. It is recommended that you do not use petroleum-based lubricants on the o-ring...they could cause it not to seal properly.

  7. The best way to reinstall the water pipe is with the thermostat attached to it. This ensures that everything is lined up correctly and deletes the difficult step of having to install the locking clip with the pipe already installed.
  8. Attach the thermostat to the water pipe. Make sure the thermostat lines up with the notch in the pipe. Install the locking clip.mini r56 water pipe replacement - Make sure the notch in the water pipe lines up with the thermostat mini r56 water pipe replacement - Fully assemble the thermostat and water pipe before reinstalling
  9. Wipe a small amount of liquid detergent around the o-ring of the new water pipe. This will lubricate it enough to slide into the the water pump. Avoid using petroleum based lubricants on rubber o-rings.Dawn liquid dish detergentmini r56 water pipe replacement - Add a small amount off liquid dish detergent to the o-ring to lubricate it.
  10. Slide the thermostat and water pipe around the rear of the engine and underneath the Valvetronic motor as shown. TAKE YOUR TIME and exercise patience. DO NOT force the pipe into place...you could crack it.mini r56 water pipe replacement - Slide the new water pip and thermostat into position in the engine
  11. With the water pipe and thermostat in place, line the pipe up with the water pump. Using two hands grasp the water pipe and press into the water pump. You may have to rotate it back and forth until it presses completely into the pump. The pipe is properly installed when its tabs are pressing against the pump (see image below).mini r56 water pipe replacement - Line the new water pipe up with the water pump Grasp the water pipe with both hands and rock it back and forth while pressing it into the water pump mini r56 water pipe replacement - A properly installed water pump
