Can an antifreeze leak wait?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

When should my Lexus SC400 radiator be cleaned?

Air pockets in your SC400’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

Is it bad to have rust on my SC400 radiator?

Yes. Rust in the radiator of your Lexus SC400 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.

Is It Time for Service on My 1994 Lexus SC400 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus SC400 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. 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 1994 Lexus SC400 is essential for long-term engine health. 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 see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Lexus SC400 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 SC400 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 1994 Lexus SC400 engine 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. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the heater core to the radiator cap, we’re here to give your 1994 Lexus SC400 the top-notch service it needs.
