radiator over flow tank

Postby HALBUDD » Fri Apr 08, 2011 3:50 pm



I have been smelling radiator fluid after my 84 aspey gets hot I have no leaks any where at all. I do notice that my over flow tank is at normal but once the engine gets hot the level rises up to above the words upper on the tank then back down to the original mark it started out on. Question is it the radiator cap not holding pressure and allowing the hot fluid to seep in to over flow tank.Or could it be something else thanks in advance. Hal

This could be a head gasket problem - the smell could be coming as it is being burned in the cylinders, and exhaust gases can be escaping into your coolant, pressurizing it and pushing the coolant into the reservoir. Are you having to add any coolant to keep it at a constant level?

Thanks WingAdmin but no it is not losing any radiator fluid at all I dont have to add any at all. I guess ill take the radiator cap off of my parts bike and put it on and see if that solves the problem. Thanks Hal

You might want to take it to a shop that has a coolant pressure tester and try pressurizing the system that way. My son has one so I lucked out that way. I could pressurize the system with the bike cold and find any small leaks I had without burning myself. I found out it was the cap is all.
