When to Service Your 1990 GMC Safari Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your GMC Safari radiator serviced, but you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. 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 1990 GMC Safari is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, GMC recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. Your radiator could be close to causing an engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

GMC Safari Coolant Fluid Exchange

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your GMC Safari’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Radiator problems often go hand in hand with water pump problems. Of all the parts in your 1990 GMC Safari engine, the water pump is one that you can't put off repairing or replacing. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. If it’s not working well (or at all), your engine can easily overheat. Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. From the radiator cap to the heater core, we’re here to give your 1990 GMC Safari the top-notch service it needs. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Questions About GMC Safari Radiators

With regular maintenance and service as needed, you could extend the life of your 1990 GMC Safari radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • 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.
  • Is an antifreeze leak dangerous? Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!
  • Do GMC Safari radiators need to be cleaned? It could be a good idea to have your GMC Safari radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • What is causing my Safari to overheat? One of the main reasons your GMC Safari 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.
  • What can cause a Safari radiator to make boiling or rumbling sounds? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Safari. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Should I be concerned about rust in my Safari radiator? Yes. Having rust in your GMC Safari radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.
