2013 MP8 fuel in the coolant.

Recommended Posts

I'm pretty sure its fuel anyway. I found it while replacing the oil cooler cover, coolant was pouring out the bottom at the front of the engine. It already had the updated cover with metal gasket. I noticed after removing the cover the rectangular rubber gasket where the cover butts up to the rear of the water pump housing was torn and swollen. At that point I pulled the thermostat and the rubber gasket was gone. Anyway I replaced all of the coolant oring seals, they all fit loose and some looked like a rat had been chewing on them. Now I'm replacing the cups and Injector orings. The engine ran fine and the injectors look real clean. I really don't see any bad orings on the cups or injectors. The injectors have two orings on them so assume that are original. I guess I should go back with just the one oring on the injectors like the new ones come. I anyone has anything to add or anything else I haven't considered please chime in. Thanks

Did the new cups fix the problem?

I am so glad I have older trucks.

The only place that the two systems come together is the injector cup area. A small imperfection or wear in the o-ring could easily let fuel past but hold off coolant pressure. Did you check the fuel tanks for coolant?
