Why is the coolant light on my Buick 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.

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

Why is my Rendezvous overheating?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Buick Rendezvous engine to overheat.

What is making my Rendezvous radiator sound like it’s boiling or rumbling?

Air pockets in your Rendezvous’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

Is rust in my Rendezvous radiator bad?

Yes. Having rust in your Buick Rendezvous 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 2003 Buick Rendezvous Cooling System

It can be tough to know when to have your Buick Rendezvous radiator serviced if you don't know what it does, 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 2003 Buick Rendezvous is a huge factor in the longevity of your engine. In fact, Buick recommends replacing coolant/antifreeze at specific 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 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.

Radiator Repair Service for Your Buick Rendezvous

What’s included in a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Buick Rendezvous’s cooling system. 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. Some services for your 2003 Buick Rendezvous engine can wait, but the water pump is one part that you can't put off repairing or replacing. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. Without it, your engine won't maintain its optimal temperature. 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, your 2003 Buick Rendezvous 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.
