Is It Time for Service on My 1990 GMC R1500 Suburban Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your GMC R1500 Suburban radiator serviced. Nonetheless, it's still extremely important. 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.

Keeping up with regular radiator maintenance in your 1990 GMC R1500 Suburban 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 a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

What to Expect from GMC R1500 Suburban Radiator Repair

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 R1500 Suburban’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 1990 GMC R1500 Suburban 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. Without it, your engine won't maintain its optimal temperature. Let our technicians examine your radiator pumps and hoses to help you stay ahead of any potential engine problems. If you’re about to lose your cool over a too-hot engine, rest assured that your 1990 GMC R1500 Suburban 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.

Common GMC R1500 Suburban Radiator Questions

Take care of your 1990 GMC R1500 Suburban 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? 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? 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 R1500 Suburban radiators need to 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 R1500 Suburban in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • My R1500 Suburban overheated! What can cause that? Your GMC R1500 Suburban engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • What is making my R1500 Suburban radiator sound like it’s boiling or rumbling? Your R1500 Suburban’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 R1500 Suburban radiator bad? Yes. Rust in the radiator of your GMC R1500 Suburban 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.
