When should my BMW 735i 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 735i in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

What is causing my 735i to overheat?

If your BMW 735i 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.

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

Should I be concerned about rust in my 735i radiator?

Yes. Rust in the radiator of your BMW 735i 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 1991 BMW 735i Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your BMW 735i radiator serviced, but it's still extremely important. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. 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 1991 BMW 735i is a huge factor in the longevity of your engine. In fact, BMW recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. Your radiator could be close to causing an engine breakdown 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.

BMW 735i Coolant Fluid Exchange

What happens during a radiator repair service? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your BMW 735i. 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.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 1991 BMW 735i engine that you can't put off repairing or replacing. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. Without it, your engine won't maintain its optimal temperature. 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’ll take excellent care of your 1991 BMW 735i at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.
