When to Service Your 1999 GMC Sierra 1500 Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your GMC Sierra 1500 radiator serviced. Nonetheless, it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. 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.

Regular, proactive service on the radiator in your 1999 GMC Sierra 1500 is essential for long-term engine health. GMC recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your GMC Sierra 1500

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your GMC Sierra 1500 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. The water pump is one part on your 1999 GMC Sierra 1500 engine that you can't put off repairing or replacing. 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. Our technicians can take a look at your radiator’s components to help you stay ahead of any potential engine problems. When it comes to radiator service and repair, we’re here to give your 1999 GMC Sierra 1500 the top-notch service it needs. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.

GMC Sierra 1500 Radiator Q&A

Take care of your 1999 GMC Sierra 1500 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? 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!
  • When should my GMC Sierra 1500 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 Sierra 1500 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • What is causing my Sierra 1500 to overheat? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your GMC Sierra 1500 engine to overheat.
  • My Sierra 1500 radiator sounds like it's rumbling or boiling! What's up? There could be air pockets in your Sierra 1500’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
  • Should I be concerned about rust in my Sierra 1500 radiator? Yes. If you have rust in your GMC Sierra 1500 radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.
