When to Service Your 1993 Lexus LS400 Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Lexus LS400 radiator serviced, but it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 1993 Lexus LS400 is a huge factor in the longevity of your engine. In fact, Lexus recommends replacing coolant/antifreeze at specific intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You could be on the verge of a radiator-induced 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. 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’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 Lexus LS400’s 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.

Radiator problems often go hand in hand with water pump problems. The water pump is one part on your 1993 Lexus LS400 engine that needs to be addressed ASAP once an issue is identified. 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. Let our technicians examine your radiator pumps and hoses to ensure everything is operating as it should. From the radiator cap to the heater core, we’ll take excellent care of your 1993 Lexus LS400 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Common Lexus LS400 Radiator Questions

With regular maintenance and service as needed, you could extend the life of your 1993 Lexus LS400 radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • 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.
  • 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!
  • When should my Lexus LS400 radiator be cleaned? Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your Lexus LS400 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • 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.
  • My LS400 radiator sounds like it's rumbling or boiling! What's up? 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 rust in my LS400 radiator bad? Yes. Rust in the radiator of your Lexus LS400 can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.
