Hi everyone,

Has anyone here installed a custom 3rd party Oil or Tranny cooler in  
an automatic 2.1L ?

Bus Boys has some that they claim are for the Vanagon and I am  
considering installing one for the oil and tranny fluids in front of  
the existing front radiator.

My rebuilt engine is going in later this week, looks great. It should  
with over $2k in parts in it! Now I just want to keep it running well.  
So the idea of adding extra cooling seems like a sound concept.

Ten Cent life on the Samba installed one using a sandwich system that  
uses the existing cooler.

I am trying to copy this European design:

What are the proper kind rubber reinforced tubing needed? PSI level,  
size, location, mounting, connectors, etc?

Dennis sent me to this site: pegasusautoracing.com
He thought this product would be good, does anyone have any other  
recommendations?

Comes with everything you need.
"Automatic Vanagons have a factory installed transmission cooler that  
uses engine coolant and the radiator to cool the fluid. This adds the  
transmission cooling load to the engine cooling system (this is less  
than ideal) and the results of a failure of this cooler are disastrous  
for both the transmission and the cooling system.

Our cooler kit keeps the two systems separate and does a better job of  
keeping the transmission fluid cool in very hot weather. Additionally,  
a failure in the system results in only a fluid leak that is easily  
repaired.

Recommended for all automatic Vanagons including those with the higher  
horsepower Subaru engines.

Our kit includes all the neccessary hardware and does not require any  
drilling or tapping of the transmission, It can be installed without  
removal of the transmission. The two 5/8" hoses to the original cooler  
can be bypassed with this mender or can be rerouted to bypass the area  
entirely.

The recommended mounting position is between the frame rails on the  
driver's side just in front of the transmission.

Price: $159.00"
