When Does My 2008 GMC Sierra 2500 HD Radiator Need Service?

It can be tough to know when to have your GMC Sierra 2500 HD 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 2008 GMC Sierra 2500 HD is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, GMC recommends replacing your antifreeze or coolant at scheduled 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 see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Wondering how to make your 2008 GMC Sierra 2500 HD radiator last as long as possible? Read on for answers to common questions, and visit your local Firestone Complete Auto Care when your engine shows any signs of a faulty radiator.

  • Why is the coolant light on my GMC 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? It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.
  • Do GMC Sierra 2500 HD radiators need to 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 GMC Sierra 2500 HD in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • My Sierra 2500 HD overheated! What can cause that? One of the main reasons your GMC Sierra 2500 HD engine might overheat is because you don’t have enough coolant. Other causes include a clogged radiator, a damaged cooling fan, a malfunctioning thermostat, or a faulty water pump.
  • What can cause a Sierra 2500 HD radiator to make boiling or rumbling sounds? Your Sierra 2500 HD’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!
