COOLING SYSTEM REPAIR
In Arizona, overheating is not a warning — it is damage
A cooling system that copes fine in a mild climate can be marginal at 115 degrees. Small leaks, a tired water pump or a lazy cooling fan show up here first, and the consequence is a warped cylinder head rather than an inconvenient tow.
We pressure test the system, find where it is actually losing coolant, and repair the cause instead of topping it off and sending you back out into the heat.
-
Pressure tested, not topped off
We find the leak before we refill anything. -
Fan and sensor diagnostics
Plenty of overheats are electrical rather than mechanical. -
Correct coolant for your vehicle
Mixing types causes its own failures. -
Checked before summer
Spring is the time to find a weak cooling system.
WHEN TO COME IN
Signs your cooling system needs work
Any one of these is worth a free inspection. An overheat gauge reading means stop driving and call us.
◑
Temperature climbs in traffic
At a standstill the fan does all the work. That pattern points straight at the fan circuit.
◉
A coolant puddle under the car
Green, orange or pink. Worth finding the source before the system empties itself.
◍
The heater blows cold
Low coolant, a stuck thermostat or a plugged heater core — all worth checking early.
◎
A sweet smell after driving
Coolant is escaping somewhere and burning off against something hot.
◐
The reservoir keeps needing top-ups
A leak you cannot see, sometimes internal. This is what a pressure test is for.
◈
Steam or an overheat warning
Stop. Driving an overheating engine is how a hose repair becomes a rebuild.

QUESTIONS WE GET EVERY WEEK
Cooling system FAQ
How often should coolant be changed?
Most manufacturers specify an interval by both time and mileage, and Arizona heat is hard on coolant. We check its condition and strength at every visit and tell you when it is genuinely due.
Can I just add water?
In an emergency, to get somewhere safe. Water alone boils sooner, offers no corrosion protection, and causes problems if it stays in the system.
My car only overheats in traffic — why?
At speed, airflow through the radiator does the cooling. In traffic, the fan does. That pattern usually means the fan, its relay or a temperature sensor.
How do you find a leak I cannot see?
We pressurize the cold system and watch where it drops, and we use dye when the leak is slow or internal.
Is it safe to keep driving a car that overheats a little?
No. Aluminium heads warp quickly, and that turns a hose repair into engine work.
Is the repair warrantied?
Yes — 24 months or 24,000 miles on parts and labor, whichever comes first.
