Product Overview
The pump maintains coolant circulation during low-speed, high-load UTV use where airflow can be limited. Coolant leakage, bearing noise, pulley play or repeated overheating should prompt inspection of the pump, belt, radiator and thermostat.
RTV900 suffixes and serial ranges can affect cooling-system parts, so the catalog reference should be checked.
Key Features & Performance
- Maintains coolant circulation: Keeps coolant moving through the engine and radiator so heat can be rejected under working load.
- Serviceable wear point: Seal leakage, shaft play, bearing noise or pulley wobble are common reasons to replace an aging pump.
- Fitment by engine and pump geometry: Casting, hub height, pulley arrangement and reference number should match the original pump.
- Product-specific note: RTV900 suffixes and serial ranges can affect cooling-system parts, so the catalog reference should be checked.

Frequently Asked Questions
How do I confirm this is the correct part?
Verify your RTV900 full model suffix, serial and original pump/casting before ordering.
Is this an OEM part?
Unless the listing is explicitly identified as genuine/OEM in the product data, treat it as a replacement component. Use the verified reference numbers, equipment application and physical configuration above to match your original part.
What should I check before installation?
Inspect belt tension and fan/pulley condition at the same time.
Fitment note: Equipment manufacturers may use different components within the same model family based on engine, serial number or production date. Confirm the original part number and machine/engine details before ordering.
