When to Service Your 1990 GMC S15 Jimmy Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your GMC S15 Jimmy 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.

Staying on top of routine radiator maintenance for your 1990 GMC S15 Jimmy 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 also wise to keep an eye out for signs of a failing radiator. You could be on the verge of a radiator-induced engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

What happens during a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your GMC S15 Jimmy’s cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Of all the parts in your 1990 GMC S15 Jimmy engine, the water pump is one that you'll want to have repaired or replaced as soon as you discover a problem with it. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range.

From the radiator cap to the heater core, we’ll take excellent care of your 1990 GMC S15 Jimmy at Firestone Complete Auto Care.

GMC S15 Jimmy Radiator Q&A

Wondering how to make your 1990 GMC S15 Jimmy radiator last as long as possible? Read on for answers to common questions, and visit your local Firestone Complete Auto Care when your engine shows any signs of a faulty radiator.

  • What does the coolant light on my GMC dashboard mean? Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.
  • Can an antifreeze leak wait? 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 Jimmy radiator be cleaned? To keep your GMC S15 Jimmy radiator running well, it’s wise to get it cleaned out a few times a year.
  • What can cause my S15 Jimmy to overheat? One of the main reasons your GMC S15 Jimmy engine might overheat is because you don’t have enough coolant. Other causes include a clogged radiator, a damaged cooling fan, a malfunctioning thermostat, or a faulty water pump.
  • Why does the radiator in my S15 Jimmy sound like it’s rumbling or boiling? Your S15 Jimmy’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!
  • Should I be concerned about rust in my S15 Jimmy radiator? Yes. If you have rust in your GMC S15 Jimmy radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.
