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?

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 Does My 2008 Lexus RX400h Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your Lexus RX400h radiator serviced, but it’s vital to know what to look for. 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.

Regular, proactive service on the radiator in your 2008 Lexus RX400h is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, Lexus recommends replacing your antifreeze or coolant at scheduled 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 leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

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 RX400h’s cooling system.

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 2008 Lexus RX400h at Firestone Complete Auto Care. After all, we know it’s not just a car.
