Is It Time for Service on My 1989 Mitsubishi Sigma Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Mitsubishi Sigma radiator serviced, 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.

Keeping up with regular radiator maintenance in your 1989 Mitsubishi Sigma is essential for long-term engine health. In fact, Mitsubishi recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Mitsubishi Sigma Radiator Repair

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Mitsubishi Sigma 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.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 1989 Mitsubishi Sigma engine can wait, but the water pump is one part 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. Let our technicians examine your radiator pumps and hoses to help you stay ahead of any potential engine problems. From the heater core to the radiator cap, we’ll take excellent care of your 1989 Mitsubishi Sigma at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Questions About Mitsubishi Sigma Radiators

Take care of your 1989 Mitsubishi Sigma radiator and it will last. Check out our top questions and answers about Mitsubishi radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • Why is the coolant light on my Mitsubishi 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? Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!
  • Can Mitsubishi Sigma radiators be cleaned? To keep your Mitsubishi Sigma radiator running well, it’s wise to get it cleaned out a few times a year.
  • What can cause my Sigma to overheat? One of the main reasons your Mitsubishi Sigma 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.
  • My Sigma radiator sounds like it's rumbling or boiling! What's up? There could be air pockets in your Sigma’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
  • There’s rust in my Sigma radiator. Should I be worried? Yes. Rust in the radiator of your Mitsubishi Sigma can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.
