When Does My 1990 GMC G3500 Radiator Need Service?

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. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. 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.

Keeping up with regular radiator maintenance in your 1990 GMC G3500 is essential for long-term engine health. To keep your radiator functioning, GMC recommends replacing your antifreeze or coolant at scheduled intervals but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. 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’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’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.

Radiator problems often go hand in hand with water pump problems. Of all the parts in your 1990 GMC G3500 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 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 help you stay ahead of any potential engine problems. From the heater core to the radiator cap, we’re here to give your 1990 GMC G3500 the top-notch service it needs. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

GMC G3500 Radiator Q&A

With regular maintenance and service as needed, you could extend the life of your 1990 GMC G3500 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 an illuminated coolant temperature light mean for my GMC? 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.
  • What are the puddles in my driveway or garage floor? 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? Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your GMC G3500 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • My G3500 overheated! What can cause that? If your GMC G3500 engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.
  • What can cause a G3500 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 G3500. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Is it bad to have rust on my G3500 radiator? Yes. Having rust in your GMC G3500 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.
