WIRING GP-CONSOLE 5058075 - Caterpillar

Personal injury can result from hot coolant, steam, and alkali.At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.Remove cooling system pressure cap slowly to relieve pressure only when engine is stopped and allow sufficient time for the cooling system to cool.Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns.Cooling System Coolant Additive contains alkali. Avoid contact with skin and eyes.
Replace the water temperature regulator on a regular basis in order to reduce the chance of unscheduled downtime and of problems with the cooling system.The water temperature regulator should be replaced after the cooling system has been cleaned. Replace the water temperature regulator while the cooling system is drained or while the cooling system coolant is drained to a level that is below the housing assembly for the water temperature regulator.
Failure to replace the engine's water temperature regulator on a regularly scheduled basis could cause severe engine damage.
Note: If you are only replacing the water temperature regulator, drain the coolant to a level below the housing assembly for the water temperature regulator.
Illustration 1 g01162907
Loosen hose clamp (1) and remove the hose from the water temperature regulator housing.
Remove bolts (2) from the water temperature regulator housing and remove the water temperature regulator housing.
Remove the gasket and remove the water temperature regulator from the water temperature regulator housing.
The water temperature regulators may be reused if the water temperature regulators are within test specifications, are not damaged, and do not have excessive buildup of deposits.
Since Caterpillar engines incorporate a shunt design cooling system, it is mandatory to always operate the engine with a water temperature regulator.Depending on load, failure to operate with a water temperature regulator could result in either an overheating or an overcooling condition.
If the water temperature regulator is installed incorrectly, it will cause the engine to overheat.
Install a new water temperature regulator and a new gasket. Install the water temperature regulator housing.
Install the water temperature regulator housing and the hose. Tighten the hose clamp.
Add the cooling system coolant. Refer to Operation and Maintenance Manual, "Cooling System Coolant Level - Check" for further information.
