What does the coolant light on my Infiniti dashboard mean?

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.

Is an antifreeze leak dangerous?

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?

If your Infiniti Q45 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.

Why does the radiator in my Q45 sound like it’s rumbling or boiling?

Air pockets in your Q45’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

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 1999 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. 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.

Keeping up with regular radiator maintenance in your 1999 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 it’s a good idea to keep your eyes open for any indication that your radiator is failing. You could be on the verge of a radiator-induced engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. 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 happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Infiniti Q45 cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Of all the parts in your 1999 Infiniti Q45 engine, the water pump is one that needs to be addressed ASAP once an issue is identified. 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 radiator cap to the heater core, your 1999 Infiniti Q45 is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
