THERMOSTAT PROBE INSTALLATION Making sure the vehicles engine is cold; drain enough coolant out of the radiator so the upper radiator hose can be removed. Warning: Coolant is a hazardous fluid, drain into container. Never open radiator cap or attempt to remove hose while motor is hot. 1. Remove radiator clamp and hose. 2. Insert thermostat probe into radiator hose. (See Diagram #2) 3. Place capillary tube on radiator inlet tube so the probe itself will remain positioned in the hose. Place the foam pad between the capillary tube and the radiator inlet tube. (See Diagram #2) 4. Carefully install radiator hose and tighten hose clamp. Note: It is recommended that a screw type hose clamp is used for correct sealing (See Diagram #3). Factory type clamps can leak. 5. Double check coolant level, fill as required.
