L405 4.4 2013 - huge coolant leak - diagram






Please help me. Huge coolant leak from the back top of engine, car in the mechanic, could you please post a Cooling Diagram

Did not find any oil in the coolant, is it possible to be the oil cooler gasket in this case?

Have also a small oil leak, looks like from the 2 o-rings

Thank Stan, I checked all the files on the L405 2013 - (Work Manual) and did not find the Cooling Diagram, have you ever seen it on the documentation?

Thank you!

I will change the oil cooler gasket today and pray it solves, if not my mechanic wants do pull the engine down as he does not have access to work between the engine and the car panel, what do you think about his plan?

Changed the oil cooler gasket, but the problem was not there, the mechanic says it may be the EGR valve, what do you guys think?

Thank you all

I know this is a bit like closing the stable door after the horse has bolted but have you pressure tested the coolant system to see where the leak is coming from? Coolant leaks can be a pain in the .... to find, there is a UV additive on the market that you put in the system to aid diagnosis. Normally on the 4.4, its either the Thermostat housing, Oil Cooler o-rings or one of the pipes.

Yes we did the pressure test, it came from the right back top of the engine, going down to the top of the starter. We drained the system and pumped smoke on it but unfortunately it did not work. We are now taking the EGR out to see if we find anything there. Thank you all for the help!
