866761 Pressure Cap | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta pressure cap of the earlier production type, from the Cooling System group, weighing 0.064 kg and listed for 16 applications across TAMD, TMD and MD series engines. Earlier production is the identifying detail, so quote it with the number - no relief pressure is published for this cap, and a cap of the wrong rating causes trouble in either direction.

🔌 Function

Holds the cooling system at its working pressure and relieves above it, raising the coolant's boiling point.

⚠️ Common Signs of Failure

• Coolant pushed out into the expansion bottle or overboard whenever the engine works
• Header tank collapsing or hoses going soft as the engine cools
• Cap seal perished, swollen or torn
• Boiling or coolant loss at temperatures the engine used to hold
• Cap sealing faces corroded or the spring gone weak

🛠️ Service Notes

• Have the cap pressure tested rather than judged by eye - one that looks fine can be relieving well under its rating
• Check the filler neck sealing face and the overflow route at the same time
