Engine Coolant Pipe – GM (85654340)

Engine Coolant Pipe is a service fluid formulated for a specific transmission or engine family. The additive package controls friction behaviour, so substituting a generic fluid changes shift quality and clutch engagement.

Change the Engine Coolant Pipe at the interval the manufacturer specifies, and always after a repair that opens the hydraulic circuit. Fluid that has been overheated smells burnt, and no additive restores it.

Ordering reference for the Engine Coolant Pipe is part number 85654340, categorised under Hoses & Pipes. Match that number against the component you are removing before you order.

Genuine GM supplied for this Engine Coolant Pipe, with the engineering number unchanged from the factory reference stamped on the original.
