Coolant Loss
I have a 2002 Accord LX 2.3 VETEC with 86K. I am losing coolant, but don't see any leaks. I have replaced the radiator, which was starting to seep at the upper tank. I also replaced the upper and lower hoses and two of the small water hoses that carry coolant to and from the throttle body. I also replaced the rad. cap, the thermostat and gasket. I don't see any white smoke from the exhaust, the car runs fine. The coolant reservoir does not leak, yet every time I fill up with gas I check the coolant reservoir and it is empty, which works out to be about every 350 miles. Has anyone else had this problem? Any ideas?
Check the transmission fluid for coolant contanination. The radiator might be leaking coolant into the transmission fluid.
Thanks, I had checked that before I changed the radiator and again afterward. The radiator had been seeping a bit from where the crimps secure the upper plastic tank, but there is no indication of coolant seepage into the trans fluid or the engine oil.
remove the spark plugs and check to see if they're wet with coolant.
fluids don't disappear. it could either be leaking from your head gasket into your combustion chamber where it is burning. or it could be leaking into the oil. so when you are at wide open throttle there is no smoke coming out? have you had someone look behind you while you try it? does under your hood smell? kinda a sweet smell? what i would do is i would pressurized your cooling system see if its holding pressure.
I own the same car as you wit bout 10,000 miles less. I would check the oil and see if its a milky color. But i really cant see the head gasket goin bad at 85k miles. Otherwise go 2 a trusted mechanic of yours and have them pressure test it. Or if ur mechnically inclined buy yourself a pressure test kit and look for leaks.
if you are mechanically inclined you could do a compression test. then a cylinder leak down test.
I have a 96 accord 4dr and im also losing radiator coolant without any obvious leaks. I do detect a burning/sweet smell from my under the hood every so often. what coukd this possibly mean??? please help
