When Does My 1991 GMC G3500 Radiator Need Service?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your GMC G3500 radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Keeping up with regular radiator maintenance in your 1991 GMC G3500 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. You could be on the verge of a radiator-induced engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Radiator Repair Service for Your GMC G3500

What’s included in a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your GMC G3500’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. The water pump is one part on your 1991 GMC G3500 engine 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. Let our technicians examine your radiator pumps and hoses to help you stay ahead of any potential engine problems. From the heater core to the radiator cap, your 1991 GMC G3500 is in good hands at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

GMC G3500 Radiator Q&A

Take care of your 1991 GMC G3500 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.
  • Is an antifreeze leak dangerous? Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.
  • When should my GMC G3500 radiator be cleaned? It could be a good idea to have your GMC G3500 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 G3500 to overheat? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your GMC G3500 engine to overheat.
  • What is making my G3500 radiator sound like it’s boiling or rumbling? Air pockets in your G3500’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.
  • Is rust in my G3500 radiator bad? Yes. Rust in your GMC G3500 radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.
