What does the coolant light on my BMW dashboard mean?

If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.

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 BMW 735iL radiators 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 735iL in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

My 735iL overheated! What can cause that?

Your BMW 735iL engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

My 735iL 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 735iL. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

Is rust in my 735iL radiator bad?

Yes. Having rust in your BMW 735iL 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.

When to Service Your 1989 BMW 735iL Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your BMW 735iL radiator serviced, 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. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 1989 BMW 735iL is essential for long-term engine health. BMW recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. 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 BMW 735iL Radiator Repair

What happens during a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your BMW 735iL’s cooling system.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 1989 BMW 735iL engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. 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. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 1989 BMW 735iL at Firestone Complete Auto Care.
