Anyone see the "fast cooler" type coolers in the latest Petersen's rag??



I'll have to get the name tonight, but they were nicer (IMO) than the fast coolers...

I saw them, on the 4500 that they put behind that 6. 2. they did look nice to me too. I bet they cost more as well.

I wish I was still in machine shop back in high school, those things are too easy to make! Just don't have the equipment anymore, even if they work great they are priced pretty high. Think I've heard others say the same thing on here too. What does everyone else think?
 
I considered buying some 1" plate aluminum and making my own by simply cutting the "hole" out with a jig saw, stacking a couple together on each side, and using the PTO cover for a template... I costed it and could have done it for under $75, but ran out of time. So I bought the fast coolers...

The actual FastCoolers are not worth the asking price, but they have sorta cornered the market. It isn't the fancy "fins" that cool, it is aluminum's heat transfer characteristics that make them work so well...

yeah, I was considering buying them but for almost $200..... I'm going to purchase the $10 PTO cover to drill and tap for the temp sensor hole and have a spare cover in case I jack up the thin metal as apposed to the fass coolers with the "NTP" hole already.

Besides, I don't tow and in the winter time I do not need any more cooling :)
 
I got mine for $160 shipped... a little savings...

The pto covers are actually quite thick, I would not be afrain to drill and tap one for a sending unit.

I guess I just got stuck in a rut... I always drill them, and braze half of a steel collar to the inside (1/8 NPT) for my sending units... did this to several things I have.

I don't have access to a welder of any sort :( hopefully nothing will leak, or it's going to be messy

When you tap, don't run the tap in too deep... run it in just enough to get the threads clear through, then try your sending unit. If it will thread through the cover, stop, if not, run the tap through a little further (not much) and try the sending unit again... repeat this until the sending unit has a full thread through the cover, and still has some exposed on the front...



The NPT is tapered... run the tap completely in and your sending unit might actually be loose whne the threads are bottomed.

Thanks or the tip!

Maybe a rubber/metal washer on both ends as well?

And were abouts in the PTO over? smack in hte middle? or near the bottom? (never popped hte cover on my transmission et)

If you look at the sending unit, there is no real "shoulder" to seat a gasket/seal against... the tapered thread is supposed to be "self-sealing"... so a little bit of pipe dope will do the trick (teflon tape might cause a poor ground, so be aware of that if you decide on tape).



I placed mine a little low in the one cover... you can judge for yourself by looking at the fill port and drawing a line across the cover, level with the fill port. That should give a good reference point. I think, IIRC, the PTO covers are almost submerged.
