When to Service Your 1993 GMC Sonoma Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your GMC Sonoma radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 1993 GMC Sonoma is crucial to keep your engine in the best possible shape for years to come. GMC recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

GMC Sonoma Coolant Fluid Exchange

What does radiator repair include? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your GMC Sonoma. 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. Some services for your 1993 GMC Sonoma engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. 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. If you’re about to lose your cool over a too-hot engine, rest assured that your 1993 GMC Sonoma is in good hands at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.

Common GMC Sonoma Radiator Questions

With regular maintenance and service as needed, you could extend the life of your 1993 GMC Sonoma radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • 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.
  • 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 Sonoma 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 Sonoma in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • Why is my Sonoma overheating? If your GMC Sonoma 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 Sonoma 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 Sonoma. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Is rust in my Sonoma radiator bad? Yes. Rust in your GMC Sonoma 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.
