Why is the coolant light on my BMW dashboard on?

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.

Do BMW 535i radiators need to be cleaned?

It could be a good idea to have your BMW 535i radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My 535i overheated! What can cause that?

If your BMW 535i 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 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 your BMW 535i radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.

When Does My 1986 BMW 535i Radiator Need Service?

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 vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. 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 1986 BMW 535i is a huge factor in the longevity of your engine. In fact, BMW recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. You could be on the verge of a radiator-induced 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

What to Expect from BMW 535i Radiator Repair

What does radiator repair include? 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 535i. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Of all the parts in your 1986 BMW 535i engine, the water pump is one that you'll want to have repaired or replaced as soon as you discover a problem with it. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. From the radiator cap to the heater core, we’re here to give your 1986 BMW 535i the top-notch service it needs. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
