Volvo Penta D1-20 genuine service parts are made to exacting standards to withstand the harsh saltwater environment in which marine diesel engines operate. If you need help with any technical issue regarding your Volvo Penta D1-20, please call us.

The heat exchanger on any D series should be cleaned and the 4 "O" rings changed, every 5 years to prevent overheating. The exhaust elbow should also be removed every few years especially if the engine is run for extended periods on low revs as there could be a build-up of carbon within the exhaust elbow. The exhaust elbow should be checked and or changed after about 10 years due to possible corrosion build-up within the saltwater jacket around the outer casing of the exhaust elbow.

Older D1-20 diesel engines may run on Volvo green coolant and newer ones may be using yellow VCS coolant. Please do not mix or change the coolant type once one or other has been used. If you are running on Volvo Penta green coolant, continue to use green coolant. Mixing yellow and green coolant can cause gelling and blockages within the cooling system.
