Diesel Overheating Diagnostics
Diesel Engine Repair — Cheyenne, WY
A diesel that runs hot under load — towing, climbing a grade, or bucking a Wyoming headwind — has a real problem that will only get more expensive. Overheating can come from a tired water pump, a plugged radiator or charge cooler, a stuck thermostat, a failing fan clutch, EGR cooler trouble, or combustion gases pushing into the cooling system from a head gasket.
Trevor tests rather than guesses: pressure tests, temperature measurements across the cooling stack, and combustion-gas checks isolate the true cause. On working trucks, he can also talk through cooling upgrades that give a hard-worked diesel more margin.
What's Included
- Overheating under tow and load diagnosis
- Pressure testing and combustion gas detection
- Water pump, thermostat, fan clutch and radiator testing
- EGR cooler and head gasket evaluation
- Cooling capacity upgrades for working trucks
Diesel Diagnosis Done Right
- Verify and inspect
Every diesel complaint starts with reproducing the symptom and a physical inspection — leaks, soot trails, boots, clamps and wiring.
- Test the systems
Compression tests, fuel system diagnostics and turbo checks isolate whether the problem is mechanical, fuel, or air.
- Confirm before replacing
Injectors, pumps and turbos are expensive. Nothing gets replaced until testing confirms it failed.
- Fix it for the long haul
Where a known weak point exists — like CP4 injection pumps or grid heater bolts — Trevor will tell you about the proven prevention options.
