It can be tough to know when to have your GMC G3500 radiator serviced if you don't know what it does, but it's still extremely important.

You guessed it – your engine overheats, and it may even break down completely.

Keeping up with regular radiator maintenance in your 1984 GMC G3500 is crucial to keep your engine in the best possible shape for years to come. In fact, GMC recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing.
