A few years ago I had a 4.6lt +8 and found that the level of oil was an important factor in the running temp of the car. With the oil half way between the marks on the dipstick it ran approx 10oC hotter than when it was up to the top mark. I can see the value of the oil cooler as it is in contact with the moving internals of the engine rather in a jacket around the block etc. Someone on the other side of the pond recently said they had a finned alloy sump (which would aid oil cooling) on their TR engined +4 and it ran at reasonable temperatures in high ambient conditions. Nevertheless a good radiator is an essential, as I established after I had mine re-cored! The manufacturers design the radiator bearing the parameters of the market the vehicle is to be sold in, or at least they should!

You seem to have invested in an oil cooler to help you cool the water, which is not logical (to me anyway). However I do respect Keith's judgement and he must have learned something about this from another car possibly. My +8 has the crossover Librands exhausts under the sump and I don't think I need an oil cooler. I do however have a larger alloy radiator which keeps my water temperature in between the thermostat opening temperature of 85 Deg C and 98 Deg when the fan cuts in. My fan only cuts in when in heavy traffic or when I am stationary, whenever I can move at a reasonable speed I have no water cooling issues. You may like the look of the cooler under the nose , but I don't think it is necessary. Modern oils are designed to run very hot , and overcooling them causes more issues generally than overheating them. If you have gained an improvement that is fine, but I suspect you would have been equally pleased , if not more so, by going for the alloy radiator.

Haven't done any motorway work yet, but I seem to be running 10-15* cooler and am running an indicated 85-95* in mixed driving - spirited and traffic and only minimal fan cutting in in stationary traffic now. I always displayed an indicated 100-120 in hot-very hot weather depending on driving style - never ever lost any coolant though. Will stave off the ally rad for a bit methinks, but will eventually give in.
