Is It Time for Service on My 1999 Lexus GS400 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus GS400 radiator serviced. Nonetheless, it’s vital to know what to look for. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 1999 Lexus GS400 is crucial to keep your engine in the best possible shape for years to come. Lexus 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. 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. 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 Lexus GS400

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Lexus GS400 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. Some services for your 1999 Lexus GS400 engine can wait, but the water pump is one part that you can't put off repairing or replacing. 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 trained technicians can inspect your car’s radiator hoses and pumps to ensure everything is operating as it should. If you’re about to lose your cool over a too-hot engine, rest assured that we’re here to give your 1999 Lexus GS400 the top-notch service it needs. After all, we know it’s not just a car. It’s your car.

Lexus GS400 Radiator Q&A

Take care of your 1999 Lexus GS400 radiator and it will last. Check out our top questions and answers about Lexus 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 Lexus? 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? 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 Lexus GS400 radiators be cleaned? It could be a good idea to have your Lexus GS400 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • My GS400 overheated! What can cause that? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Lexus GS400 engine to overheat.
  • What can cause a GS400 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 GS400. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • There’s rust in my GS400 radiator. Should I be worried? Yes. If you have rust in your Lexus GS400 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.
