Bowie69 Posted December 7, 2018 Share Posted December 7, 2018 Before assuming that, get the coolant checked for combustion gasses, that will rule a head gasket in or out. 1 Quote Link to comment Share on other sites More sharing options...
JohnnoK Posted December 8, 2018 Share Posted December 8, 2018 It sounds like the oil heat exchanger has failed. It lives on the left side of the engine below the exhaust manifold/behind the oil filter and is available as a replacement part. There are also aftermarket ones available that offer better resistance to corrosion, but if you use the correct antifreeze, you should be OK on an OEM one. Have a good look at the housing while you are in there, the pipe spigot is a good point for corrosion and subsequent misery as your coolant leaks out and strands you. 1 Quote Link to comment Share on other sites More sharing options...
rach Posted December 12, 2018 Author Share Posted December 12, 2018 hi friends i found the problem, it's the oil cooler that had holes causing by the rust. but the cooler costs a bit expensive, so I opt for another system, I found on the net, I hope it will work, just the time for me to have the price for the cooler, your opinion is precious thank you to let me know.

JohnnoK Posted December 14, 2018 Share Posted December 14, 2018 That should work as a temporary fix, but watch your temperatures in the heat, you might find it starts running hot. 1 Quote Link to comment Share on other sites More sharing options...
