1977 to 1985 Diesel Special 24 mm Oil Filter Housing Fitting Wrench

A Must Have Tool when dealing with stubborn oil cooler hoses

This standard 24 mm combination wrench is specially ground in our shop so that it will hold the fitting on the late 616 and 617 oil filter housing when loosening the oil cooler hose end nut. Without this wrench the fitting may start to turn with the hose nut and you will never get it off. There is just not enough room behind the oil cooler hose nut to get a standard thickness 24 mm open end wrench.

By using our other special wrench as shown below you will be able to successfully remove the oil cooler hose from the fitting without damage.

The thickness of the head has to be reduced to about 60 percent of the original thickness as shown below:
