Tired of Overheating Kubota D1105 and Bobcat 753 Engines? Replace Thermostat 6680512 Before the Next Failure

One failed thermostat can shut down a Kubota D1105-powered loader or Bobcat 753 skid steer for days — costing $2,000+ in idle time per day. Many customers report repeated failures from non-OEM thermostats that open at incorrect temperatures or leak under pressure. OEM replacements take 3–4 weeks and cost up to 45% more than verified aftermarket options.

OEM-Equivalent Quality, Ready to Ship from Guangzhou Warehouse

This thermostat 6680512 is manufactured in ISO 9001-certified facilities and tested for opening temperature accuracy (±1.5°C), pressure integrity (up to 1.2 bar), and cycle durability (10,000+ thermal cycles). We’ve supplied over 12,000 units to repair centers across North America and Southeast Asia since 2021 — all for Kubota D1105 and Bobcat 753 applications where consistent coolant regulation is critical during continuous digging or grading operations.

Where This Part Works

This thermostat operates in high-duty-cycle environments: urban demolition sites where ambient temps exceed 40°C, quarry loading operations with frequent load spikes, and port-side material handling under salt-laden air. In these conditions, inaccurate coolant flow leads directly to cylinder head warping, gasket failure, and premature engine wear — especially on Kubota D1105 and Bobcat 753 skid steer loaders running 10+ hours daily.

Engineering Details That Matter

The brass housing resists corrosion from ethylene glycol-based coolants and maintains dimensional stability after repeated thermal cycling. The wax element is calibrated to open fully at 82°C ±1.5°C — matching OEM specifications exactly to prevent low-temperature cavitation or high-temperature boil-over. Silicone rubber seals withstand continuous exposure to 120°C coolant without hardening or extrusion. Precision-machined flange surfaces ensure zero leakage at the engine block interface — eliminating the need for re-torquing or sealant during installation.

The Real Cost of Wrong Parts

A $12 counterfeit thermostat may save $8 upfront but often fails within 200 operating hours — triggering overheating, warped heads, and $1,800+ in labor and parts to rebuild the cooling system. Our 6680512 thermostat meets ISO 9922:2017 thermal actuation standards and delivers 3× longer service life than uncertified alternatives. Total cost of ownership drops 62% over 2 years when factoring in downtime avoidance, reduced labor, and extended engine life — especially for fleet operators managing multiple Kubota D1105 and Bobcat 753 units.
