Is It Time for Service on My 1990 Nissan Pathfinder Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Nissan Pathfinder radiator serviced, but it’s vital to know what to look for. 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 1990 Nissan Pathfinder is essential for long-term engine health. Nissan 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 might be driving around (or about to be stranded) with a failing radiator 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.

Nissan Pathfinder Coolant Fluid Exchange

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Nissan Pathfinder 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.

Radiator problems often go hand in hand with water pump problems. The water pump is one part on your 1990 Nissan Pathfinder 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’s not working well (or at all), your engine can easily overheat. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the radiator cap to the heater core, we’re here to give your 1990 Nissan Pathfinder the top-notch service it needs. After all, we know it’s not just a car. It’s your car.

Common Nissan Pathfinder Radiator Questions

Take care of your 1990 Nissan Pathfinder radiator and it will last. Check out our top questions and answers about Nissan radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • Why is the coolant light on my Nissan 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.
  • 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!
  • Do Nissan Pathfinder radiators need to be cleaned? It could be a good idea to have your Nissan Pathfinder radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • My Pathfinder overheated! What can cause that? Your Nissan Pathfinder 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 Pathfinder radiator to make boiling or rumbling sounds? Your Pathfinder’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!
  • Should I be concerned about rust in my Pathfinder radiator? Yes. If you have rust in your Nissan Pathfinder 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.
