Cosworth Duratec/MZR Oil and Water Control / Miscellaneous

An efficient cooling system is essential in maintaining the engine’s performance under all operating conditions.

Although the complete system will depend upon the individual installation, it is vital that the water pump and thermostat are working as designed. Questionable parts should be replaced. Cosworth cylinder head water outlets are designed to simplify installation of a Duratec mounted in an inline, rear drive or any other application that requires additional clearance at the back of the cylinder head. Cosworth offers several types suitable for most installations.

For sustained high speed use, a low speed water pump pulley helps to reduce pump cavitation and maintain a constant flow of water.

With high performance applications a substantial amount of heat is rejected to the oil system. The oil temperature should be stabilised to maintain peak performance. The Cosworth oil cooler kit is designed to cool the oil as it flows through the oil filter. The kit includes the water to oil heat exchanger and a new oil filter housing designed to replace the standard component.
