Tips for replacing oil cooler gaskets.

[Iroll_]

Hi team,
After replacing my coolant hose gaskets hardline & oil return tube gaskets I recently went on a trip and noticed I am leaking a drop or two of oil from behind my oil cooler.
I have the gaskets in order. Before I start the repair, any tips/pointers on what I should prepare myself for?

There are two o-rings that seal the cooler to the oil pan. Very easy to replace, but the dealer charges a crazy price for them.

Thanks Astro.
Yes, the local dealer would like $23.00 per seal.
eBay saved my bacon'.

Any tips on which product to use for cleaning the surfaces that I'll be working with?
I was thinking of brake cleaner but have learned to ask than to assume with repairs I have no experience with.
