IS YOUR ENGINE RUNNING HOT?

In Phoenix summers, a weak cooling system is the fastest way to a breakdown or serious engine damage. Overheating, low coolant or a sweet smell under the hood all mean it is time for a check.

We test and repair radiators, water pumps, thermostats, hoses and more. For car overheating repair in Phoenix that holds up in the heat, we keep your temperature gauge right where it belongs.

Our technicians handle radiator replacement, radiator hose replacement, water pump repair and thermostat replacement for Chrysler, Dodge, Jeep, Nissan and Mitsubishi vehicles. Catching a coolant leak early, and getting the coolant leak repair done, can keep a small job from turning into an engine replacement.

“In Arizona, a healthy cooling system isn’t optional – we make sure yours can handle the heat.”

Radiator Repair in Phoenix You Can See for Yourself

Nothing ends a Phoenix commute faster than a temperature gauge climbing into the red. In this video, George shows a radiator and cooling system repair up close. It’s the kind of work that keeps an engine from overheating on the I-17 in the middle of August.

Every Cooling System Repair Starts With a Pressure Test

Before we replace anything, we:

  • Pressure-test the system
  • Inspect the radiator, water pump, thermostat, hoses, and cap
  • Test the coolant itself

Coolant breaks down faster in Arizona heat, losing its ability to carry heat and prevent corrosion. Many leaks only appear under pressure, so a dry driveway does not mean a healthy system. We show you what we find and explain your options. Every cooling system repair in Phoenix we complete is backed by the NAPA AutoCare nationwide warranty.

What Your Temperature Gauge Is Telling You

These three symptoms point to three different problems:

  • A gauge that creeps up in traffic: often a failing fan or a thermostat that needs replacement. See our guide to bad thermostat symptoms.
  • A sweet smell or colored puddle under the car: a coolant leak, often from a hose or the water pump.
  • Steam from under the hood: a problem that needs engine overheating repair today.

Driving while overheated can warp heads and lead to engine repair. A cracked radiator hose is often part of a larger belts and hoses issue. A regular coolant flush prevents most of these failures. If the A/C goes warm when the gauge climbs, see our A/C service.

If your car is overheating, pull over and shut it off. Then call or schedule online and we will find the cause and give you the price in writing first. Larger repairs qualify for Synchrony financing.

SIGNS YOU NEED COOLING SYSTEM SERVICE

Stay alert to these common warning signs – fix them early and save on bigger repairs.

1

Car overheating

If your temperature gauge keeps rising toward the red, stop driving and get it checked right away.

2

Coolant leaking under car

Green, orange, or pink puddles under your car point to a leak that can get worse if left unrepaired.

3

Sweet smell or white smoke

A sweet smell or white smoke from the exhaust can be a sign of a coolant leak or a more serious engine problem.

4

Heater or A/C not working

Cooling and heating share components, so trouble with one often shows up in the other.

FAQs

Why is my car overheating?

The most common causes are a coolant leak, a stuck thermostat, a failing water pump, a clogged radiator or a cooling fan that isn’t working. Less often, it’s a head gasket. A cooling system pressure test finds the cause quickly, and it’s the first step in every radiator repair in Phoenix we perform.

Pull over safely and turn off the A/C. Turning the heater to full hot can pull some heat from the engine. If the gauge is in the red, shut the engine off. Never open a hot radiator cap. Then call us at (602) 759-9354 rather than driving further.

A high reading usually means the engine isn’t shedding heat: low coolant, a stuck thermostat, a weak water pump or a cooling fan that isn’t turning on. If it climbs only at idle or in traffic, the fan is the usual suspect. Have it checked before it reaches the red.

Follow your owner’s manual, which typically calls for it every 30,000 to 100,000 miles depending on the coolant type. Phoenix heat breaks coolant down faster, so we test its condition at every service and recommend a coolant flush when it tests weak.

Coolant leaking from the front of the engine, a whining or grinding noise, a wobbly pump pulley and overheating. Pete Kelley’s replaces water pumps, thermostats and radiators with quality parts, and every radiator repair in Phoenix is quoted in writing before we start.

A small leak at a hose or cap is a repair. A cracked tank, a clogged core or corrosion through the fins means radiator replacement. We pressure-test first and show you the fault before quoting either one.
