For an oil cooler to be as affective as possible the heat it removes should
not be added back into the heat the radiator must deal with.
I just got into this discussion, so I hope the following is not a repeat.
There are many ways to improve the Healey cooling. Some are simple such as:
Make sure you are using a thermostat that includes a bypass blocking sleeve or
install a fixed sleeve to stop the flow from bypassing (the radiator).
In lieu of using a 50/50 mix of anti-freeze, use 10-15% antifreeze & 90-85%
water. You will be protected down to something like 10 degrees F. If that is
not enough, increase the percentage in the winter.

Bob: I installed an oil cooler many years ago. It was not an 'official' model
but the largest I could install in front of the radiator without blocking the
radiator too much. I installed temp sending units in the oil pan for engine
oil temp and in the return line from the cooler. Temperature drop was 5
degrees. No noticable difference on the Healey temp gauge. For me and my
installation, not worth the effort. Took it all out.
