Two problems related to engine and engine cooling have been reported for the 2003 Chevrolet S10. The most recently reported issues are listed below.
2003 chevy S10 has been maintained and taking care of. Brakes in rear were sticking due to factory defective abs control module. Rear wheel bearing gave out and started leaking axle fluid cause of a sticking drivers side brake from abs control module malfunctioning. After much cost of replacing calipers and brake pads the culprit from a defectively abs control module making the brake caliper stick to the rotor. . Next the coolant leaks from the intake manifold gasket and now the heater core leaks… this truck has only 146k miles on it and I always taking care of it keeping up before it’s schedule maintenance. But what I see is poor defective parts from gm. So I have to make sure I get this work done and keep the coolant filled or there be a motor issue from overheating. This is a safety concern and if the heater core leaks then breathing the toxic coolants isn’t safe at all when the ac is on or no heat in winter!. Now gm discontinued making the S10 in north America but redesigned a front wheel drive diesel version in south America.
