When Does My 1990 Mitsubishi Sigma Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your Mitsubishi Sigma radiator serviced, but you need to know the signs of radiator malfunction. 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.

Keeping up with regular radiator maintenance in your 1990 Mitsubishi Sigma is essential for long-term engine health. To keep your radiator functioning, Mitsubishi 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 could be on the verge of a radiator-induced engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. 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 Mitsubishi Sigma

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 Mitsubishi Sigma. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Of all the parts in your 1990 Mitsubishi Sigma engine, the water pump is one 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. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 1990 Mitsubishi Sigma at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Common Mitsubishi Sigma Radiator Questions

With regular maintenance and service as needed, you could extend the life of your 1990 Mitsubishi Sigma radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • What does the coolant light on my Mitsubishi dashboard mean? Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.
  • Can an antifreeze leak wait? 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.
  • When should my Mitsubishi Sigma 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 Mitsubishi Sigma in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • My Sigma overheated! What can cause that? If your Mitsubishi Sigma 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 Sigma radiator to make boiling or rumbling sounds? Your Sigma’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!
  • Is rust in my Sigma radiator bad? Yes. If you have rust in your Mitsubishi Sigma 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.
