When Does My 2003 Infiniti FX45 Radiator Need Service?

It can be tough to know when to have your Infiniti FX45 radiator serviced if you don't know what it does, 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. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 2003 Infiniti FX45 is a huge factor in the longevity of your engine. In fact, Infiniti recommends replacing coolant/antifreeze at specific 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 a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your Infiniti FX45

What’s included in a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Infiniti FX45’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 2003 Infiniti FX45 engine 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. Without it, your engine won't maintain its optimal temperature. Let our technicians examine your radiator pumps and hoses to help make sure everything is in working order. From the heater core to the radiator cap, your 2003 Infiniti FX45 is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Infiniti FX45 Radiator Q&A

Wondering how to make your 2003 Infiniti FX45 radiator last as long as possible? Read on for answers to common questions, and visit your local Firestone Complete Auto Care when your engine shows any signs of a faulty radiator.

  • Why is the coolant light on my Infiniti dashboard on? 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? 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.
  • Can Infiniti FX45 radiators be cleaned? It could be a good idea to have your Infiniti FX45 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • Why is my FX45 overheating? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Infiniti FX45 engine to overheat.
  • Why does the radiator in my FX45 sound like it’s rumbling or boiling? Your FX45’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!
  • Is rust in my FX45 radiator bad? Yes. If you have rust in your Infiniti FX45 radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.
