I think my car's getting sick again. As of late, the idel has roughend up again, and i can smell coolent when the thing heats up to normal running temp. The car is due for a service, and as for leaks, well there doesnt appear to be any. Suggestions?

Is it using coolant?

And as I stated last time about glycol smell:

"If its slowly leaking you should be able to see coolant around the cork sump gasket,

Also Have you looked behind the exhaust manifold between cyl 5 & 6? if its wet it sounds like a typical head gasket.

Hope its not a head gasket, It could as simple as the plastic Bung in the water tank of the radiator on the OFF-SIDE (10mm plug). "

The smell of coolant was my first sign of a head gasket failure not to scare you, but its worth looking into. and if it is, it'll be a good saturday for ya!

hope this helps

hmm, same as me only mine wasnt head gasket, it was HEAD. you beta prey against that one!

yeah im getting used to that smell replacing my gasket this weekend

THAY HAD A BAD HABIT FOR STRECHED HEAD BOLTS. I HOPE THAT IT IS ONLY A BAD RAD CAP .ALSO CHEACK THE O RING ON THE WATER PUMP SIDE IT MIGHT BE LEAKING AND SPAYING ONTO THE EXHAUST.
