It uses the “Kangaroo Pouch” style housing, driven by a 61‑tooth helical gear, and includes a replacement O‑ring kit. The pump circulates coolant through the engine block and radiator to maintain proper operating temperature; it is typically replaced when a leak develops at the weep hole, the bearing becomes noisy, or during a major overhaul to prevent unexpected overheating.
