What does an illuminated coolant temperature light mean for my BMW?

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.

What are the puddles in my driveway or garage floor?

To keep your BMW 735iL radiator running well, it’s wise to get it cleaned out a few times a year.

My 735iL overheated! What can cause that?

If your BMW 735iL engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.

What can cause a 735iL radiator to make boiling or rumbling sounds?

There could be air pockets in your 735iL’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Is it bad to have rust on my 735iL radiator?

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.

Is It Time for Service on My 1990 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 you need to know the signs of radiator malfunction. 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.

Regular, proactive service on the radiator in your 1990 BMW 735iL is a huge factor in the longevity of your engine. 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 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.
