Unfortunately, time and a lack of coolant changes frequently take their toll on your Chevy Truck Heater Core, causing small leaks and reduced flow through the system.
If you've changed your antifreeze religiously every two years or so, you may not have any crud built up in your Engine Parts.
Besides, a new OEM Part, particularly when you buy it here, isn't that expensive.
The Chevy Truck Heater Core is the heart of your car's heating system, utilizing engine heat to warm up the passenger compartment on cold mornings.
