Why is the coolant light on my BMW dashboard on?

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.

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.

When should my BMW 535i 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 BMW 535i in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

What is causing my 535i to overheat?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your BMW 535i engine to overheat.

What can cause a 535i 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 535i. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

Should I be concerned about rust in my 535i radiator?

Yes. Rust in the radiator of your BMW 535i 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 1990 BMW 535i Cooling System?

It can be tough to know when to have your BMW 535i radiator serviced if you don't know what it does, but it's still extremely important. 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.

Keeping up with regular radiator maintenance in your 1990 BMW 535i is essential for long-term engine health. To keep your radiator functioning, BMW 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. Your radiator could be close to causing an 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Radiator Repair Service for Your BMW 535i

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 BMW 535i’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.

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 1990 BMW 535i engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. This vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature. Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. From the heater core to the radiator cap, your 1990 BMW 535i is in good hands at Firestone Complete Auto Care.
