bbigrig Posted November 23, 2013 Share Posted November 23, 2013 Lots of those wonderful O-ring seals on all the piping thanks to Volvo. Most of your cooling system and piping runs on that side of the motor so you will have to be more specific as to the area its leaking on an MP series motor. If it looks like it is coming from a bolted on cover affixed to the passenger side of the engine its the oil cooler cover which has been known to leak. (behind the EGR cooler) Take another look. It could be a lot of things with coolant on the turbo side of the motor.

Challenger Posted November 24, 2013 Share Posted November 24, 2013 Also check the coolant hose clamp under the tstat. Get a flash light and look back in there, you would need a 7mm socket and long extension to back there and tighten the clamp. We've seen loose clamps causing regular leaks or cold leaks.
