I don't know, just made an assumption - not always a good idea :Stop:I didn't think an oil cooler was a BYPASS system????
Another cheap way, if you have the room, is to use a larger oil filter. it adds a few more sq. inches of cooling area to the "can" and a couple oz. more capacity.
I installed the filter on mine which is similar to what is included in the kit shown. There is an adapter plate that goes between the block and the oil filter to divert the full flow through the cooler before it gets to the filter.The stock command cooler hooks on inline ahead of the oil filter, Id assume cause I dont own one that it just passes through it like a filter...Ive seen them but I dont use them on our pullers so Ive never really sat down and looked to hard.....
I have seen but not used one of those.There is also a more basic cooler that looks like this-
I do wonder if there are passages inside this one, or if it just acts as a large heat sink. If its just a heat sink, doesnt seem like a very worthwhile upgrade.
