Water Temperature Regulator - Remove and Install

SMCS - 1355-010

Removal Procedure

i01148678

At operating temperature, the engine coolant is hot and under pressure.

Steam can cause personal injury.

Check the coolant level only after the engine has been stopped and the filler cap is cool enough to touch with the bare hand.

Remove the filler cap slowly to relieve pressure.

Cooling system conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.

NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.

NOTICE

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.

Dispose of all fluids according to local regulations and mandates.

1. Drain the coolant level below the water temperature regulator.

Illustration 1 g00609693

a. Put the water temperature regulator in a tub of water. Heat the water in order to test the water temperature regulator for thermostatic action.

Note: Stir the water in the tub in order to maintain even temperature during the test.

b. When the valve of the water temperature regulator lifts more than 10 mm (0.4 inch), measure the water temperature.

Note: The opening temperature for the water temperature regulator is 71° ± 2°C (160° ± 3.6°F).

c. If the valve fails to operate properly, replace the water temperature regulator.

Installation Procedure

NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.
