Had my '02 SC2 in the shop Monday. Valve tapping was pronounced a little louder than normal so the tech looked at my car and gave it a clean bill of health. He suggested that changing the engine coolant temp sensor may help in quieting my engine and possibly help it run smoother. My warranty covered it, seemed harmless, so I said ok.
When I got home from work , a 45 min drive, I smelled coolant - real strong. I hate the smell of coolant more than farts or BO. (once blew a heater core in my old 'stang going 100, never forget that stink) So I took out the hose and some Simple Green and rinsed off the spillage that the mechanic left that came out when changing the ECTS. Spillage is normal, but I was hoping that as I brought him a sparkling clean engine, I would get it back just as clean. He also said that he "topped off" my reservoir after changing the ECTS.
Smelled coolant again tonight when I got home. I drive all highway, 45 - 75 mph. Popped the hood, and was coolant traces on the top of the radiator reservoir and down the engine chassis (under the pulleys) as if coming from the screw-on cap or a hose was dripping??. At first I feared it was a leaky hose, so I rinsed it off and drove a few miles. Got home, popped the hood and more coolant! Not lots, but enough that it stinks.
So I'm wondering, bad cap or any chance that the coolant reservoir was over filled and the cap is designed to leak like that? Did I mention that I hate the smell of coolant? TIA.
