§ 02 Our approach
How we handle cooling system
We pressure-test the system and cap, check coolant condition and concentration, and verify thermostat, fan and water pump operation with real temperature readings. Charge air coolers get a separate boost leak test because a leaking CAC can look like a fuel problem.
Repairs include radiator and charge air cooler replacement, water pumps, thermostats, hoses and clamps, fan clutches and fan hubs, heater core issues and coolant service to the engine maker’s specification.

§ 05 FAQ
Cooling System questions
My truck is overheating — should I keep driving?
No. Pull over safely and shut down if the gauge is near the red. Continuing to drive can damage the head gasket or engine. Call us and we will come to you.
How often should coolant be changed?
It depends on the coolant type and engine maker’s interval. We check condition and additive levels at every PM so you change it when it is actually needed.
Can you fix a charge air cooler leak?
Yes. We test for boost leaks and replace leaking charge air coolers, hoses and clamps.
