Aux oil and tranny cooler questions
I'm planning to add auxiliary oil and tranny coolers to my rear engine bus. The question is where to place them. Their placement also determines if I include fans on the coolers or not.
1) My research has alluded to, yet not specified, about the importance of flow and PSI when adding a cooler.
If anyone knows how to figure this out, please share.
2) The placement of the transmission cooler is suggested to be on the return line. This way the fluid is going back in already cooled.
The oil cooler uses an adapter that goes between the oil filter male port and the oil filter itself. The adapter also has the ports for the cooler lines.
3) Per the placement of the actual coolers. Attached our pictures of my radiator. I removed the back cover and measured the gap between the radiator and the back cover, which is 2.75".
I believe this is more than enough space to place the actual coolers. Included in the pictures show a channel, one on each side of the radiator, that provide great access to the oil filter and hopefully the transmission return line.
While they coolers would block about 4" of the radiator, they would be down low and not interfere with the intercooler, which I believe sits up high.
4) I researched the types of coolers and feel that the stacked plate coolers provide the highest cooling effect. If I do place them in front of the radiator, I won't use a fan. Otherwise I will use a fan.
5) I have not done any research on how to control the flow to the coolers. I'm sure there's some type of thermostatic valve? I'll research it, but any input is welcomed.
