Setrab oil cooler, Can two small ones be run in series? Options

[rtalich]

Ordered the smaller setrab unit with fan to replace the oil cooler that was installed when I bought the car (pictures). The new setrab unit is way smaller than I thought it would be. In fact, it's about half the size of what's installed now. I'm pretty sure the bigger setrab unit with the double fans is too big for this space. Anyone see issues if I run two of these smaller units in series? That way I can install them staggered and will fit in that space quite nicely.

In referance to posts #18 and #19:

Yes that is a cross flow cooler as are most of the other ones mentioned in this thread. That design is a stacked plate cooler having been sold under Long Mfg, Borg Warner and other manufacturers names. Not really better. They lack fins and are air side limited on heat dissipation.

How many radiators have you seen made after 1930 that did not have fins?

They do not flow air well. Long Mfg used to have the BTU heat rejection listed on their website showing this style cooler clearly removes less heat that a similar plate and fin cooler.

The design dates back to WWII where it was used as an aircraft cooler ( P-38 ?) with very high air speed and fins could get flattened.

They also need to be rubber mounted to prevent vibration damage. Ford used them as power steering coolers on diesel trucks with a high failure rate. Not a good choice for an under body cooler in the hot & poor airflow area under a 914 trunk. Regardless of what cooler you use an oil temp gauge will tell you if you have enough cooler.
