1991 Chevrolet S10 Blazer ProblemsCoolant Leak From Heater Core
The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.
A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

No light comes on so can't check code.
water pump doesn't leak at all, car hasn't overheated, don't know what check gauge light means, and does the belt that goes to everything have to be replaced if there are no rips or holes, if i change the water pump.
