Cooling system checks
A thermostat controls when coolant begins to flow to the radiator, so a unit stuck closed lets the engine run hot, while one stuck open keeps it running cool and can reduce heater output. Symptoms of a failing thermostat include temperature gauge swings, slow warm-up and coolant leaks around the housing. Diesel engines depend on steady cooling for combustion, so catching a fault early helps avoid bigger repairs.
When replacing the thermostat, renew the gasket or seal at the housing, and clean both mating surfaces before assembly. Check the radiator cap and hoses for wear at the same time, since a weak cap can cause boiling even with a new thermostat. Top up with the correct coolant, run the engine to temperature and check the gauge and the housing for seepage.
- Renew the housing gasket or seal
- Inspect the radiator cap and hoses
- Check the coolant level after the first drive

Installation notes
Let the engine cool completely before opening the cooling system, and use the correct coolant for the engine. Bleed air from the cooling system, then check for leaks and the coolant level after the first drive. Keep the part number with your records, and inspect the part and its fasteners periodically, especially after off-road use. Gather the tools and fasteners needed before starting, and work in a clean, well-lit area.
