"Part nos: 22912546 block to hose fitting. 22840081 hose. I did not replace the hose to oil cooler fitting"

Why did you decide not to replace oil cooler fitting? Do you need any sealant on the fitting, or just the gasket on the fittings?

Thanks again for the writeup

Hi Chris,

I didn't discover that the fitting to hose gasket is part of the fittings until after I had ordered the parts. So if you want to replace both gaskets with the hose, then replace the fitting at each end.
