What We Do

Complete Cooling System Care & Repair

From a simple leak to a complete engine overhaul, our specialists handle every cooling system challenge with the same meticulous attention to detail.

Radiator Repair & Replacement

Aluminum, brass, and plastic tank radiators. We fix leaks, clogs, and internal failures — often saving you from a full replacement.

AC Repair & Recharge

Durham summers demand a reliable AC. We diagnose compressor failures, condenser leaks, and refrigerant issues fast.

Heater Core Service

No heat in the cabin? We test, repair, and replace heater cores — including those tricky access jobs on modern vehicles.

Water Pump & Thermostat

Coolant circulation is everything. We replace worn water pumps, stuck thermostats, and failing seals before they strand you.

Cooling System Flush

Old coolant turns corrosive. Our multi-point flush removes sludge, rust, and contaminants to protect your engine's lifespan.

Performance Upgrades

Towing heavy? Tracking weekends? We install high-capacity radiators, electric fans, and oil coolers built for serious use.

About Us

Durham's Trusted Cooling System Experts

North Hills Auto Radiator has been a fixture in the Durham automotive community for over two decades. We started as a small radiator repair shop and grew into the region's go-to destination for complete cooling system expertise.

Unlike general repair shops that treat cooling systems as an afterthought, we live and breathe this one system — every day, every vehicle. That depth of focus means faster diagnosis, more accurate repairs, and solutions that actually last.

We serve everything from daily commuters and family SUVs to commercial fleet vehicles and classic cars. No job is too routine or too specialized. If it runs hot, we can fix it.

Testimonials

Words from Durham Drivers

"My truck was overheating on the highway and I pulled into North Hills with no idea what to expect. They diagnosed the problem in minutes, had me back on the road the same afternoon, and the price was exactly what they quoted. That's rare."

"I've been bringing all my vehicles here for years. They fixed a leak that two other shops couldn't find, and they've never once tried to sell me something I didn't need. Honest, skilled, and fast."

"Our AC died in the middle of July — not a great place to be in Durham. North Hills got us in the same day, replaced the condenser, and recharged the system. Cool air within the hour. Lifesavers."
