I just ran the car for 1 hour thru heavy stop and go traffic. The temp outside today is 40 degrees Fahrenheit. The fan never came on during or after the drive. The temp gauge reached the half way mark and went no further.
When I stopped the car I noticed two things that concern me.
First, as soon as I got out of the car, I could smell the sweet smell of DEX-COOL coolant. Looking under the hood, I could see no coolant leakage.
Second, I noticed that the level of coolant in the surge tank never moved. It’s was the same level as when the car was cold.
It makes me wonder if the thermostat is operating properly. I did notice that both the upper and lower radiator hose were hot to the touch and so was the surge tank so I would think that the thermostat did have to open even if ever so slightly. I checked all hose clamps and all are tight.
I have yet to test the relays. If they are not extremely expensive, I think I will by some to test with and just to have some on hand if ever needed.
At this point, my main concern is that I can smell coolant.
Any thoughts anyone?
