Few things ive been working on..

- Grab handles with crappy plastic thing that easily broke. Replaced with chain link and welded it with a quick dip in a water bucket to cool it down.. Now I can tighten the crap out of the straps with out breaking the plastic crap..

- Steering cool - ebay find $.99 (+$8 shipping) :D Kenworth truck power steering cooler. It's steel outter tube, 5/8" hose for coolant lines, SAE8 fittings for the steering.

The inside has a bundle of metal tubes that run the length with copper plate fins over the tubes.. It's all welded up inside.

need to slap that on when I finally hook up my hydro..
 
Mike. Just kinda wondering how that cooler will work. I always thought that you needed air flowing over the cooling fins, which are connected to the cooling tubes, to get, er.....cool, via the transfer of heat from the tubes to the fins, which is cooled and transfers the cool back to the tube, to the fluid inside.

Basically, his "air" will be engine coolant.
Its a heat exchanger, heat will equalize itself, ie go from the hot fluid to the cool fluid. As long as the hydro fluid is hotter than the engine coolant, the hydro fluid coming out of the cooler will be less hot than when it went in. To figure how much cooler it will be depends on the flow rates, temp. differentials between coolant and hydro fluid, tube lengths, material properties, and probably some other things I'm forgetting.
 
This style cooler is similer to the internal tranny cooler that would be inside your radiator to cool the trans. Some fins/plates with coolant sucking heat off it... This is just an smaller/external version of that. (Actually my wifes 04 mazda3 has an small pancake external style tranny cooler. I was trolling ebay and found this one)


Also I'm not an enginere but the liquid -> liquid cooler is X (I don't know 5 maybe) times better than liquid-> Air which is why the units are smaller than a similar rated air cooler.

BUT all that said this can/will dump more heat back into the radiator system, so if your cooling system isn't good this isn't a good setup..
 
True Mike, a liquid-liquid heat exchanger is more thermally effficient but consider your cooling media starts about 180-F instead of ambient air. That said I never put a temp guage on my PS system so I'm not sure what a "normal" tem p would be.

Want me to test your grab handles?
