Testimonials

What our clients say.

Genuine experiences, trusted service, quality, and customer satisfaction!

My car was constantly overheating, and no one could seem to figure out why. Took it to Ignition and they diagnosed a faulty thermostat and a cracked radiator hose. They fixed it all quickly and now my temp gauge stays perfectly steady. Honest shop with great techs.

I was losing coolant fast and worried I had a blown head gasket. Ignition did a pressure test and found the issue was just a leaking water pump. They replaced it the same day and even flushed the system. Car’s running like new again. Highly recommend.

After dealing with a mystery coolant leak for weeks, I brought my car to Ignition Powersports. They found a small crack in my radiator that other shops missed. Fast repair, fair price, and excellent customer service. These guys know what they’re doing.

My old radiator was shot and the engine kept running hot. Ignition replaced it fast and even replaced the coolant with the correct mix for Arizona heat. They explained everything clearly and didn’t charge a penny more than they quoted.

I was getting constant dashboard warnings about engine temperature. Brought my car into Ignition and they found the fan wasn’t kicking on due to a bad sensor. They fixed it quickly and now my car stays nice and cool even in the summer heat. So glad I found this shop.

Cooler engines. Longer life. Drive with Ignition.

How often should I flush my coolant?

Every 2–5 years or 30,000–50,000 miles, depending on your vehicle and coolant type.

Is it safe to drive if my car is overheating?

No. Pull over and turn off the engine immediately. Overheating can cause engine failure or a blown head gasket.

How do I know if my radiator is leaking?
