dirty :taco: said:Well, The car has had a "Check Coolant" light on since I bought it and the car never fully warms up (I thought this was a good thing, I guess not). The previous owner told me that the cap needed replaced. 50resto has them for $30somethin bucks including the sensor. So I guess im gonna replace the thermostat first, then the sensor & cap, then Ill try the spacer fix.
Before you buy a new overflow cap/sensor, try cleaning up the metal tips on the end of the sensor. Over time they get dirty and fail to function.
good luck
