Have a 97 Deville, had been leaking coolant slowly, after engine had warmed up it was dripping by passenger front tire ( down the boot area), also associated with? AC would only blow hot air.
Took it in, was told that I needed a new thermostat and a backflush told them to do it if it would fix problem. Now over a 20 mile trip had to pull over 3 times as engine was too hot to drive, had to add coolant as was low. Is it possible that they put a bad thermostat in or should I be worrying more that either they screwed something up when they worked on it or a new problem has arisen?
I took it back, they said the fan was not coming on, and they replaced 3 relays. Also stated they ran power to the fan and it works. Claims it may have to do with the ECU and they aren't qualified to check any further than they have.
Any suggestions? Thanks
