Is It Time for Service on My 1999 Lexus LS400 Cooling System?

It can be tough to know when to have your Lexus LS400 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Staying on top of routine radiator maintenance for your 1999 Lexus LS400 is essential for long-term engine health. To keep your radiator functioning, Lexus recommends replacing your antifreeze or coolant at scheduled 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 see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Lexus LS400 Radiator Repair

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Lexus LS400 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. Some services for your 1999 Lexus LS400 engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Let our technicians examine your radiator pumps and hoses to help make sure everything is in working order. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 1999 Lexus LS400 at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.

Questions About Lexus LS400 Radiators

Wondering how to make your 1999 Lexus LS400 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.

  • What does the coolant light on my Lexus dashboard mean? 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 Lexus LS400 radiators be cleaned? To keep your Lexus LS400 radiator running well, it’s wise to get it cleaned out a few times a year.
  • My LS400 overheated! What can cause that? Your Lexus LS400 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 LS400 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 LS400. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Is it bad to have rust on my LS400 radiator? Yes. Rust in your Lexus LS400 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.
