Frequently Asked Questions

What is the most common sign that I need a new thermostat?

The most common signs are engine overheating (gauge consistently reading high) or, conversely, the engine running too cold (not reaching operating temperature), often accompanied by erratic temperature gauge behavior.

Are aluminum radiators better than copper/brass radiators?

For modern vehicles, aluminum radiators are generally preferred. They are lighter, more corrosion-resistant, and offer superior heat transfer efficiency, especially in multi-row designs, making them excellent for high-performance or heavy-duty applications.

How do I know if my engine mounts need replacing?

Symptoms of failing engine mounts include excessive engine movement or lurching when accelerating or braking, noticeable vibrations inside the cabin, and loud clunking or banging noises when shifting gears or driving over bumps.

What does a fuel water separator do?

A fuel water separator, particularly important in marine and diesel applications, removes water and particulate contaminants from the fuel before it reaches the engine, preventing corrosion, injector damage, and engine failure.
