When Does My 1989 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, it’s vital to know what to look for. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. When the radiator isn't working properly, your engine can overheat and potentially break down.

Regular, proactive service on the radiator in your 1989 GMC G3500 is essential for long-term engine health. In fact, GMC recommends replacing coolant/antifreeze at specific 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 a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your GMC G3500

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 G3500’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 1989 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. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the heater core to the radiator cap, we’re here to give your 1989 GMC G3500 the top-notch service it needs. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.

Questions About GMC G3500 Radiators

Wondering how to make your 1989 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.

  • Why is the coolant light on my GMC dashboard on? 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? 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.
  • 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? 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.
  • Why does the radiator in my G3500 sound like it’s rumbling or boiling? 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!
  • Is rust in my G3500 radiator bad? Yes. Rust in the radiator of your GMC G3500 can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.
