1991 Chevrolet S10 Blazer ProblemsDriveability Problems Due to Internal Distributor Fault
The distributor may develop internal faults. This can cause a rough running engine or stalling condition, the Check Engine Light may or may not illuminate. Our technicians tell us that the distributor should be overhauled or replaced to correct this concern.
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.

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.
