When Does My 1991 Lexus LS400 Radiator Need Service?

It can be tough to know when to have your Lexus LS400 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.

Staying on top of routine radiator maintenance for your 1991 Lexus LS400 is essential for long-term engine health. Lexus recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You might be driving around (or about to be stranded) with a failing radiator 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Lexus LS400 Coolant Fluid Exchange

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Lexus LS400 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.

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 1991 Lexus LS400 engine, the water pump is one that you'll want to have repaired or replaced as soon as you discover a problem with it. 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. Our trained technicians can inspect your car’s radiator hoses and pumps to help you stay ahead of any potential engine problems. When it comes to radiator service and repair, we’ll take excellent care of your 1991 Lexus LS400 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Lexus LS400 Radiator Q&A

Wondering how to make your 1991 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 an illuminated coolant temperature light mean for my Lexus? Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.
  • 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 LS400 radiators be cleaned? It could be a good idea to have your Lexus LS400 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • What can cause my LS400 to overheat? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Lexus LS400 engine to overheat.
  • What is making my LS400 radiator sound like it’s boiling or rumbling? 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.
  • There’s rust in my LS400 radiator. Should I be worried? Yes. Having rust in your Lexus LS400 radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.
