1988 GMC S15 Radiator Service

When to Service Your 1988 GMC S15 Cooling System

It can be tough to know when to have your GMC S15 radiator serviced if you don't know what it does, but it’s vital to know what to look for. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 1988 GMC S15 is essential for long-term engine health. To keep your radiator functioning, GMC recommends replacing your antifreeze or coolant at scheduled intervals but you can also take note of any signs your radiator is going bad. You might be driving around (or about to be stranded) with a failing radiator if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Questions About GMC S15 Radiators

Take care of your 1988 GMC S15 radiator and it will last. Check out our top questions and answers about GMC radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • What does the coolant light on my GMC dashboard mean? Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.
  • What are the puddles in my driveway or garage floor? It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.
  • When should my GMC S15 radiator be cleaned? It could be a good idea to have your GMC S15 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
