The Chevrolet Express 3500 has been in production since 1996. If payload or maximum gross weight is important to you, the Express 3500 is a good choice. Express 3500 comes with plenty of quality parts, including the heater core parts. The heater core is responsible for letting you see clearly out of the windshield on cold days. But bad parts can cause the vehicle to overheat engine.
Express 3500 has many merits. But problems arise after heater core parts have been used for a long period. The most common signs of bad Express 3500 heater core parts include: a sweet smell inside of the vehicle, cold air when the heater is turned on, coolant puddles inside the vehicle, and the engine overheating/running hotter than normal. The steps are as follows: Drain the cooling system to avoid loss of coolant during removal. Then remove the mounting hardware, the heater core plates, and clamps. Then gently pull heater core hoses and connections off, remove the base holding the heater core in place (if equipped), finally pull upward on heater core to remove from vehicle. We offer fast delivery and reliable parts for all customers. We put much emphasis on the quality of different Express 3500 parts and accessories.
