Why is the coolant light on my Infiniti dashboard on?

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?

Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.

Do Infiniti Q45 radiators need to 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?

My Q45 radiator sounds like it's rumbling or boiling! What's up?

Should I be concerned about rust in 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.

When to Service Your 1990 Infiniti Q45 Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Infiniti Q45 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. 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 Infiniti Q45 is a huge factor in the longevity of your engine. Infiniti recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

What to Expect from Infiniti Q45 Radiator Repair

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Infiniti Q45 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 Infiniti Q45 engine that you'll want to have repaired or replaced as soon as you discover a problem with it. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it’s not working well (or at all), your engine can easily overheat. Our technicians can take a look at your radiator’s components to help make sure everything is in working order. From the radiator cap to the heater core, we’re here to give your 1990 Infiniti Q45 the top-notch service it needs. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
