I've been smelling coolant on occasion and I can't tell where its coming from. I have no white smoke, only blue smoke sometimes but I'm pretty sure its because my valve stem seals are bad. Ijust dump some no smoke in and it's fine. Anyway, I replaced my radiator, my thermostat and hoses recently and my fan won't stop running. As far as I can tell there's no leaks and I'm not losing fluid. Also, I don't see any coolant in my oil or vice versa so I'm pretty sure my head gasket is OK. Haven't been able to do a leakdown test, but there are no signs like the last time i blew a hg
