Is It Time for Service on My 1990 Buick LeSabre Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Buick LeSabre radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. 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.

Regular, proactive service on the radiator in your 1990 Buick LeSabre is essential for long-term engine health. To keep your radiator functioning, Buick recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. Your radiator could be close to causing an engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Buick LeSabre Radiator Repair

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Buick LeSabre 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.

Issues with your radiator often coincide with a malfunctioning water pump. The water pump is one part on your 1990 Buick LeSabre 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 ensure everything is operating as it should. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 1990 Buick LeSabre at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Buick LeSabre Radiator Q&A

Wondering how to make your 1990 Buick LeSabre 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 Buick 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.
  • Can an antifreeze leak wait? 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 Buick LeSabre radiators need to be cleaned? It could be a good idea to have your Buick LeSabre radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • Why is my LeSabre overheating? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Buick LeSabre engine to overheat.
  • What is making my LeSabre radiator sound like it’s boiling or rumbling? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your LeSabre. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • There’s rust in my LeSabre radiator. Should I be worried? Yes. If you have rust in your Buick LeSabre 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.
