When to Service Your 1988 GMC G2500 Cooling System

It can be tough to know when to have your GMC G2500 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Keeping up with regular radiator maintenance in your 1988 GMC G2500 is a huge factor in the longevity of your engine. In fact, GMC recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad.
