Question about Chevrolet Tracker
My Geo tracker 95 shows overheat on the front board but no need to add any coolant when you check in the radiator. What to do?
Track the top hose from the radiator back to the engine where it should run into a rounded housing. This is the thermostat housing. Next time the vehicle shows its running close to 180 or higher (dont let it get too hot or your engine will fail completely)
With the engine to temp, squeeze the upper radiator house. If it is hard then your have pressure running through the line, so then check the lower one. If no pressure, its your water pump.
if hose can be squeezed, then the thermostat is not opening and allowing the coolant to circulate. Smack the housing a few times with some hard and blunt until you feel pressure in the hose again, or the temp gauge begins to regulate (if this is the case, you need a new thermostat; they are about $5 at any auto parts store......just remember to replace the gaskets while your at it)
GOOD LUCK AND PLS RATE THIS POST!!!!!!
