Installation Notes

  1. Ensure the engine is completely cool before beginning work.
  2. Drain the engine coolant to a level below the thermostat housing.
  3. Carefully remove the bolts securing the thermostat housing cover.
  4. Note the orientation of the existing thermostat before removing it from the housing.
  5. Thoroughly clean all mating surfaces of the housing and cover, removing any old gasket residue.
  6. Install the new thermostat and gasket, ensuring they are correctly aligned as per the original.
  7. Re-secure the housing cover and tighten bolts to the manufacturer-specified torque settings.
  8. Refill the cooling system with the recommended type and amount of coolant.
  9. Start the engine, check for leaks, and monitor the temperature gauge to confirm the thermostat opens correctly as the engine warms up.

Troubleshooting & FAQ

How do I know if my thermostat is failing?

Common signs of a faulty thermostat include engine overheating, the engine running too cold (temperature gauge stays low), erratic temperature fluctuations, or coolant leaks from the thermostat housing area.

What is the significance of the 60°C temperature rating?

This thermostat begins to open at 60°C (140°F). This specific temperature is designated by the manufacturer for certain raw-water cooled engines to ensure they reach optimal operating temperature quickly without overheating or over-cooling. Using the correct temperature thermostat is critical for engine health and efficiency.

Is this kit compatible with the 2003T turbocharged engine?

Yes, this thermostat kit is listed as compatible with the Volvo Penta 2003T model (43 HP) manufactured between 1986–1993, which specifies an OEM part number of 877355.

Does this kit include the required gaskets or seals?

This kit is confirmed to include one thermostat (replaces 877355). Information regarding included gaskets was not available. Please inspect product photos or contact us to confirm if gaskets are included or must be purchased separately.

What happens if I use the wrong temperature thermostat?

Using a thermostat with a different temperature rating can lead to poor engine performance. A lower-rated thermostat may cause the engine to run too cool, increasing fuel consumption and engine wear. A higher-rated one can lead to overheating, risking severe engine damage.

My engine isn't on the list, but my manual cites a matching part number. Can I use this?

Yes. If your engine's service manual specifies Volvo Penta part number 877355, 875779, or 876691, this kit is the correct aftermarket replacement, even if your specific model designation is not included in our compatibility list.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

Shipping speed & cost?
