Turbosleeper Posted February 20, 2010 Author Report Share Posted February 20, 2010 SIGH So I have changed the water pump and did the timing belt at same time. Yet I overheat still. I have also done the thermostat and flushed the system. I dont know what else it could be. I guess I will check for exhaust gasses and pray there are none present in the coolant. There are no other signs of headgasket except the overheating part. I dont want to give up but I dont know what else to do Link to comment Share on other sites More sharing options...
Ihatespeedbumps Posted February 20, 2010 Report Share Posted February 20, 2010 A failed headgasket is unmistakable. Hard starts, huge plumes of white smoke, overpowering smell of coolant, oil in your reservoir. As long as you didn't let it boil over, you still have a prayer that you didn't destroy your head gasket. That and I know you just installed an MBC, so be very careful because detonation is another culprit that can lead to head gasket failure. Definitely replace your timing belt and water pump and keep us posted. No. One of my 95 turbos had a blown head gasket and the car ran fine. No smoke from the exhaust and it never overheated. I only found it had a blown head gasket after I went through a gallon of coolant in a few days. The blown head gasket was only revealed with a combustion leak checker like this http://www.amazon.com/UVIEW-560000-Combustion-Leak-Tester/dp/B000NPDL76 Link to comment Share on other sites More sharing options...
Turbosleeper Posted February 21, 2010 Author Report Share Posted February 21, 2010 Ok so my car just overheated again just now and I decided to feel the radiator hose from engine block to lower rad and it was cold and the top rad hose was hot. Is that normal? Link to comment Share on other sites More sharing options...
Turbosleeper Posted February 21, 2010 Author Report Share Posted February 21, 2010 Ok sorry guys to keep posting about this topic but I jsut had a though. When the engine is hot, the thermostat opens and lets the water flow through to the top of the radiator to cool it down and it comes out the bottom of radiator and back into the engine for circulation, correct? So if my top rad hose is hot, that is because its the hot water from the engine wanting to be cooled. If the the radiator is blocked then that would explain the cold hose at the bottom. This would also cause the excess pressure and coolant boiling over in the reservoir. Therefore my radiator must be clogged even though its brand new? Is it a hard job to replace radiator? Ive managed to do timing belt and waterpump already Link to comment Share on other sites More sharing options...
Guest wheelsup Posted February 21, 2010 Report Share Posted February 21, 2010 Take the hoses off the radiator and put a water hose to the top port and see if it flows thru to the bottom one (drain the fluid first). PS too lazy to login Link to comment Share on other sites More sharing options...
Guest rthompson Posted February 21, 2010 Report Share Posted February 21, 2010 You may not want to hear this but I had exactly the same problem. It ended up being the head gasket. the repair was $1,600 bucks but I was able to fix it before it was completely blown... The head gasket is letting air into the system which reduces the boiling temp of your anti freeze. Link to comment Share on other sites More sharing options...
Turbosleeper Posted February 22, 2010 Author Report Share Posted February 22, 2010 I just called a mechanic and he said over the phone that it could possibly be an intake manifold leak? Could he be right? How does coolant get near the intake? Link to comment Share on other sites More sharing options...
Fudge_Brownie Posted February 22, 2010 Report Share Posted February 22, 2010 I just called a mechanic and he said over the phone that it could possibly be an intake manifold leak? Could he be right? How does coolant get near the intake? My guess is that he thinks the leak is causing you to run lean, which generates more heat. Not something I'd suspect is causing you to overheat. Particularly because when you start getting on the gas and begin boosting, you're going to lose metered air and begin to run rich instead of lean with an intake manifold leak. Did you try to run water through the radiator? Shouldn't take too much time. Just two hose clamps. If you did need to replace the radiator, someone who can replace a waterpump can replace a radiator. No worries labor-wise. Link to comment Share on other sites More sharing options...
Turbosleeper Posted February 22, 2010 Author Report Share Posted February 22, 2010 Yes Ive ran water with a hose through the entire system. i just cant see it being the headgasket. I have absolutely no clear symptoms other then overheating and coolant loss. I went to a part store today to trry and buy a coolant pressure tester but they dont have such a thing. would checking the cylinder compression give me a positive answer? If my compression turns out to be good, what would my next step be? Link to comment Share on other sites More sharing options...

I have a 98 V70 and about 7 or 8 months ago it didn't exhibit any of those symptoms (hard start, plumes of white smoke, smell of coolant, oil in reservoir, overheating), only the boiling over of the reservoir. It was the head gasket. I suspect that the duchebag who sold it to me had put some sort of stop leak, and that's why it didn't show any of the regular HG signs. But who knows, hopefully it's something simpler for the OP. Good luck. Link to comment Share on other sites More sharing options...

GET A BLOCK LEAK TESTER KIT. Link to comment Share on other sites More sharing options...
