Is It Time for Service on My 1990 Cadillac Eldorado Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Cadillac Eldorado radiator serviced. Nonetheless, it’s vital to know what to look for. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. 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 Cadillac Eldorado is essential for long-term engine health. In fact, Cadillac 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 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.
