havent had my evo 8 long but i was pushing it a little hard and realized the coolant was leaking its coming from right near the thermostat and fully track down where, ive replace the thermostat seal so its not that. also as long as i dont jump on the gas it doesnt leak bad and the temperature didnt raise.
any suggestions
thanks

 

Check the hoses on o them might be a little loose, leave your car running and turn on the heater full blast. This will get the coolant running in the system, you should be able to see where its leaking from. If not go get the leak finder from the auto store that come with the cool glasses.

 

There is also a gasket where the thermostat housing bolts to the block. It could have blown that gasket, I think theres 5 bolts around the housing that hold it to the block.

 

Yeah, just pressure test it. There are the little hoses and the gasket that mates to the head from the thermostat housing

 

celice2evo i replaced the gasket.
i pressured tested it and i can see where its coming from kinda its covered up by all the hoses in that area but i can barely see the spray as i give it throttle think i got it pretty narrowed down
thanx guys

 

i checked it one more time. looks like its coming from. under the thermostat and about half an inch about the vin tag on the engine block and towards the middle of the block.
very hard to see under there haha
any ideas?

 

its coming from one of the two coolant lines that go from the back of the head to the throttle body. feel them up and down and see if you feel cracks. in my case, i couldnt feel cracks. but if you squeeze them, they might squirt coolant out. find the one that has the leak and replace it. i just used reinforced fuel line from autozone.

check those, then come back in here and thank me.

 

ill check its slightly dripping down the head but im hoping its one of those hoses.
thanx ill check it out tomorrow when its light out an let you know

 

any help?

 

so its not the hoses i mentioned?

 

my guess its one of the heater core hoses, one hose connects right around behind the area of the thermostat housing??....so look for a whitish residue around the hoses where they connect....if u need a picture of heater core hoses, use search
good luck
