Is It Time for Service on My 1986 GMC G3500 Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your GMC G3500 radiator serviced, but it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 1986 GMC G3500 is a huge factor in the longevity of your engine. To keep your radiator functioning, GMC recommends replacing your antifreeze or coolant at scheduled 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 see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

GMC G3500 Coolant Fluid Exchange

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your GMC G3500 cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for 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 1986 GMC G3500 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 vital part keeps coolant moving through the engine, hoses, and radiator. 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. When it comes to radiator service and repair, we’ll take excellent care of your 1986 GMC G3500 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Common GMC G3500 Radiator Questions

Wondering how to make your 1986 GMC G3500 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 an illuminated coolant temperature light mean for my GMC? 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? 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 G3500 radiators need to 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.
  • Why is my G3500 overheating? Your GMC G3500 engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • What can cause a G3500 radiator to make boiling or rumbling sounds? Your G3500’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 G3500 radiator? 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.
