Additional oil cooler Options

[cal914]

I have a 6 engine that has been uprated to 2.2 with E cams,the temp gauge keeps edging the red part of the gauge ,I e been told by the guy who rebuilt the engine that I probably need another oil cooler,can you only have these fitted in the front boot space or are there other places in the engine bay that they can be fitted
Hope this makes sense
Thanks Brian

Lots of experience here on the board and I have worked at it too.

My experience with a 2.4 S motor is that under every day driving that you should find temps manageable without a second cooler. Long highway cruising and getting into it hard for sustained romps seem to be the most problem times. Even then you should be able to stay under 210 even on hot days. I made sure that my shroud was well sealed especially around the oil cooler and I also have the modified baffles.

I highly recommend that you check your timing. I think that retarding a few degrees off of the recommended max advance and running around 28 - 30 degrees makes a huge difference without materially effecting performance (especially with higher compression than stock). Lean mixtures can also contribute to hot running.

I do believe that the rear mounted coolers do help. I built one with extensive ducting and a thermostat control that kept me cool even at the track on fairly hot days. One problem is with over pressuring these coolers with cold oil. Having a warm up bypass is necessary if you want to run in the winter.

I think your options are
1) Check your systems carefully - make sure you are not running lean and that timing is "conservative" and that your cooling system (fan and shroud) is working well WITH NO AIR LEAKS.
2) If #1 helps, live with it.
3) If still marginal, try the under trunk cooler with a fan. I think it is worth about 15 degrees.

Good luck.
