Is It Time for Service on My 1991 Infiniti Q45 Cooling System?

It can be tough to know when to have your Infiniti Q45 radiator serviced if you don't know what it does, but it's still extremely important. 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.

Keeping up with regular radiator maintenance in your 1991 Infiniti Q45 is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, Infiniti 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Infiniti Q45 Coolant Fluid Exchange

What’s included in a radiator repair service? 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 Infiniti Q45. 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 1991 Infiniti Q45 engine that you can't put off repairing or replacing. 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 technicians can take a look at your radiator’s components to ensure everything is operating as it should. When it comes to radiator service and repair, we’ll take excellent care of your 1991 Infiniti Q45 at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Common Infiniti Q45 Radiator Questions

Take care of your 1991 Infiniti Q45 radiator and it will last. Check out our top questions and answers about Infiniti radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • What does an illuminated coolant temperature light mean for my Infiniti? 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!
  • Can Infiniti Q45 radiators be cleaned? It could be a good idea to have your Infiniti Q45 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • Why is my Q45 overheating? Your Infiniti Q45 engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • What can cause a Q45 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 Q45. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Is it bad to have rust on my Q45 radiator? Yes. Rust in your Infiniti Q45 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.
