When to Service Your 1990 Cadillac DeVille Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Cadillac DeVille radiator serviced, but you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. 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 Cadillac DeVille is essential for long-term engine health. To keep your radiator functioning, Cadillac recommends replacing your antifreeze or coolant at scheduled 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 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 Cadillac DeVille Radiator Repair

What happens during a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Cadillac DeVille’s 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 Cadillac DeVille engine that you can't put off repairing or replacing. This vital part keeps coolant moving through the engine, hoses, and radiator. 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’re here to give your 1990 Cadillac DeVille the top-notch service it needs. After all, we know it’s not just a car. It’s your car.

Cadillac DeVille Radiator Q&A

With regular maintenance and service as needed, you could extend the life of your 1990 Cadillac DeVille radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • What does an illuminated coolant temperature light mean for my Cadillac? If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.
  • 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!
  • Can Cadillac DeVille radiators be cleaned? To keep your Cadillac DeVille radiator running well, it’s wise to get it cleaned out a few times a year.
  • My DeVille overheated! What can cause that? If your Cadillac DeVille 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 is making my DeVille 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 DeVille. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • There’s rust in my DeVille radiator. Should I be worried? Yes. Rust in the radiator of your Cadillac DeVille 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.
