a TiiCo conversion in an automatic V'gon? Directions a little
lacking? Let me try to explain what I did regarding the coolant
hoses for the radiator and tranny cooler. (Pictures to follow)
I should give a brief overview of the stock setup as far as how
it relates to the conversion.
are two large radiator pipes/hoses and two smaller tranny cooler
hoses. Rad hose 1 (as I'm calling it) goes from the radiator straight
back to the engine on the right (passenger) side of the tranny.
Rad hose 2 goes from the radiator to the rear of the van, but
crosses over the tranny from right to left, then connects to the
stock thermostat housing on the left (driver's) side of the tranny.
are also two tranny cooler hoses that connect to the radiator
hoses. Tranny cooler hose 1 goes from the tranny to a large T
connection in the radiator hose between the plastic pipe (in the
later V'gons) and the "coolant distributor". Tranny
cooler hose 2 goes from the tranny into the radiator hose that
crosses over the tranny.
issues to deal with here are the fact that we can't cut a hose
in half and use each half to join the plastic pipes to the metal
pipes as the directions say to. That won't work with the automatic.
The reason is that the hose they say to cut in half is that large
T hose between Tranny cooler hose 1 and Rad hose 1. Because of
this we need to find a different way to connect the plastic pipes
to the metal ones. The second issue is that tranny cooler hose
2 is WAY too short to go where it needs to go.
soon as I realized what had to be done, I went to a FLAPS (in
my case Autozone). I took one of the metal pipes (included in
the TiiCo kit) with me. The FLAPS had 5/8" heater hose by
the foot and I just purchase about 5' of it (better to have too
much than too little). Unfortunately the FLAPS didn't have the
larger diameter hose by the foot. What they did have was a whole
rack behind the counter with various different molded radiator
hoses. I ended up getting a molded hose that was L shaped and
the correct diameter to fit snugly over the metal pipe. That L
shaped hose had a long enough straight section that I could cut
it into two smaller straight pieces to do what I needed.
next thing I did was cut tranny cooler hose 1 right where it connects
to the larger (T) radiator hose 1 and connect it to the smaller
hose fitting on the shorter metal pipe. The rest of that T hose
was discarded. In its place, to join the the original plastic
pipe of Rad hose 1 to the shorter of the two metal pipes, I used
one of the short sections cut from the molded radiator hose. That
solved everything with Tranny cooler hose 1 and Rad hose 1.
Tranny cooler hose 2 was way too short, I used the 5/8" heater
hose I bought from the FLAPS. I removed the original hose from
the tranny and put one end of the new heater hose on in its place.
I then ran the new hose right along side of tranny cooler hose
1 and connected it to the longer metal pipe that replaced the
rad hose going over the tranny. Now, both radiator pipes run right
next to each other and both tranny cooler hoses run next to each
other as well.
