Tired of Overheating Kubota Engines? Get the Right Water Pump & Thermostat Kit for Your D1005/D1105
Every hour a Kubota tractor or excavator sits idle due to cooling system failure costs operators hundreds — sometimes thousands — in lost productivity. Counterfeit water pumps leak within weeks; mismatched thermostats cause erratic temperature spikes and premature head gasket failure. OEM parts take 3+ weeks to arrive, halting critical field work during peak season.
OEM-Equivalent Quality, Ready to Ship from Guangzhou Warehouse
This Kubota water pump and thermostat kit is manufactured in ISO-certified factories, rigorously tested for flow rate, pressure seal integrity, and thermal response before shipment. Designed for high-duty cycles on compact tractors and mini-excavators like the KX61-2, it delivers consistent coolant circulation and precise temperature regulation — exactly as specified for D1005 and D1105 engine platforms. With 10,000+ SKUs in stock and 10 years’ export experience, we ship verified replacements fast — no guesswork, no delays.
Where This Part Works
This kit operates under demanding conditions: agricultural fields with extended run times, construction sites where dust clogs radiators, demolition zones with frequent thermal cycling, and port logistics operations requiring uninterrupted uptime. In these environments, a failing water pump or stuck-open thermostat directly compromises engine longevity, increases fuel consumption, and risks catastrophic overheating — especially in air-cooled variants or tightly packed engine bays like those in the B2400D and KX61-2.
Engineering Details That Matter
The water pump housing is precision-cast aluminum with a hardened steel impeller shaft, ensuring resistance to cavitation erosion and maintaining rated flow at 2,800 RPM. The thermostat uses a calibrated wax-element actuator (15531-73014) opening at 82°C ±2°C — matching OEM thermal thresholds to prevent cold-start wear and hot-idle boil-over. All sealing surfaces are machined to ≤0.05 mm flatness tolerance, eliminating gasket compression failure. The included gasket set features nitrile rubber compound rated to 150°C, resisting degradation from ethylene glycol coolant blends used across Kubota’s global fleet.
The Real Cost of Wrong Parts
A $35 counterfeit water pump may save $15 upfront — but causes bearing failure in 200 hours, leading to $1,200 in labor, $800 in replacement parts, and 2 days of machine downtime. A non-compliant thermostat shifts engine operating temperature outside ISO 8528-1 thermal specifications, accelerating cylinder liner wear and increasing NOx emissions. Total cost of ownership (TCO) favors certified aftermarket kits: this Kubota D1105 thermostat and water pump kit meets SAE J1927 flow performance standards and carries full warranty coverage — protecting your repair investment long-term.

Frequently Asked Questions
Q: Is this an original Kubota part or an aftermarket replacement?
A: This is an OEM-equivalent aftermarket kit, produced in ISO-certified factories to match Kubota’s dimensional, material, and performance specifications — not sourced from Kubota.
Q: How do I confirm this fits my specific machine?
A: Provide your full model (e.g., B2400D) and serial prefix if available — our technical team verifies compatibility using official Kubota service data and responds within 2 hours.
Q: What is the warranty period?
A: 3–12 months against manufacturing defects. If failure occurs due to material or workmanship, we cover replacement and return shipping.
Q: What is the minimum order quantity?
A: 1 piece — no bulk requirement. Ideal for urgent maintenance or verifying fit before larger orders.
Q: How soon will my order ship?
A: In-stock items ship within 2–5 working days. Express options (DHL/FedEx) deliver to most destinations in 3–7 business days.
Q: Can I receive a sample before placing a bulk order?
A: Yes — first-time customers may request one sample kit for physical verification and bench testing prior to full order.
