When Does My 1991 BMW 735iL Radiator Need Service?

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. 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.

Regular, proactive service on the radiator in your 1991 BMW 735iL is crucial to keep your engine in the best possible shape for years to come. BMW recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. 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.

BMW 735iL Coolant Fluid Exchange

What’s included in 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 735iL. 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 735iL engine that needs to be addressed ASAP once an issue is identified. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it’s not working well (or at all), your engine can easily overheat. Our technicians can take a look at your radiator’s components to help you stay ahead of any potential engine problems. If you’re about to lose your cool over a too-hot engine, rest assured that your 1991 BMW 735iL is in good hands at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Questions About BMW 735iL Radiators

With regular maintenance and service as needed, you could extend the life of your 1991 BMW 735iL radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • 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.
  • 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.
  • When should my BMW 735iL radiator be cleaned? It could be a good idea to have your BMW 735iL radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • What is causing my 735iL to overheat? 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? 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!).
  • Should I be concerned about rust in my 735iL radiator? Yes. If you have rust in your BMW 735iL radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.
