i have a 2011 buick luccerne i was in a accident i to i took it to a shop they wanted $7,000 to fix it all the damage is cosmedic the car is getting hot no leaks any were could it be the thermostat
Can you help? how do we test the thermostat? no leaks found. it is running hot.
If you suspect thermostat just replace it. Impacts can damage a lot of electrical components, relays, fan motors, even computers, if it is cosmetic make sure the air flow isn’t blocked or restricted.
Are the cooling fans working? Could have damaged the fan circuits. Otherwise, Overheating can be caused by several issues. Low on coolant, leaks (internal or external), clogged radiator, bad thermostat, cooling fans not running, etc.
