What does an illuminated coolant temperature light mean for my Volvo?

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?

Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!

Is It Time for Service on My 1991 Volvo 780 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Volvo 780 radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 1991 Volvo 780 is essential for long-term engine health. In fact, Volvo 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 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.
