What does the coolant light on my Buick 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.

Can an antifreeze leak wait?

Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!

Is It Time for Service on My 1986 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, it’s vital to know what to look for. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 1986 Buick LeSabre is a huge factor in the longevity of your engine. Buick 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 could be on the verge of a radiator-induced engine breakdown 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.

What to Expect from Buick LeSabre Radiator Repair

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 Buick LeSabre. 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. Some services for your 1986 Buick LeSabre engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. 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 trained technicians can inspect your car’s radiator hoses and pumps to ensure everything is operating as it should. From the heater core to the radiator cap, we’ll take excellent care of your 1986 Buick LeSabre at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.
