Is It Time for Service on My 1991 GMC Syclone Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your GMC Syclone radiator serviced, but it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. 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 1991 GMC Syclone is essential for long-term engine health. GMC recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Let our technicians examine your radiator pumps and hoses to ensure everything is operating as it should.
