Coolant Pump, Removing and Installing

Coolant Pump Assembly Removing and Installing

WARNING!
When the engine is hot, the cooling system is under pressure. The hot coolant may escape and cause scalding injuries if the system is opened too quickly.
If necessary, open the cooling system carefully in order to slowly relieve the pressure and avoid scalding.

Notes:
Hose connections are secured with spring-type or screw-type clamps.
Use clamp pliers, Hazet 798-5 or equivalent, to remove and install spring-type clamps.
During repairs, spring-type clamps may be replaced with screw-type clamps.

For Coolant Drain and fill (Refill) procedures refer to Cooling System, Service and Repair, Procedures.
