1676307 Spring | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta spring is a calibrated compression spring used in the cooling-system compression spring. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it applies controlled preload to the designated cooling-system valve, seal or retaining component. Selection must be confirmed by OEM part number 1676307, the exact engine/product model, serial number and the installed assembly configuration.

🔌 Function

The spring applies a controlled tension load to hold or return a mechanical component to its rest position. Consistent spring force is required for the associated linkage or assembly to operate and reseat correctly.

⚠️ Common Signs of Failure

• Loss of tension so the component no longer returns fully to its rest position
• Permanently stretched or deformed coils
• Corrosion, pitting or surface cracking of the spring wire
• Fractured or broken spring, often at a hook or end loop
• Rattling or slack movement in the linkage the spring controls

🛠️ Service Notes

• Compare the new spring with the old for free length, wire diameter and number of coils before fitting; springs that look alike often have different rates
• Never stretch, shim or cut a spring to change its behaviour, and never refit one that has taken a set, is pitted, or shows a bright rubbed patch from coil clash
• Where springs work as a set, renew the whole set together so the loading stays even
• Fit the spring the way it came out where the ends or the coil pitch differ from one end to the other, and make sure it seats fully in its locating step or pocket
• Keep the spring and its seat clean and check for corrosion — a corroded spring in a fuel or engine assembly is a broken spring waiting to happen
