I had one problem that reared its ugly head shortly after the restoration, It was one of the engine running hot (I did the usual and checked for head gasket leaks and used a probe to give me the correct water temp reading).

I decided to upgrade the radiator and fit a 14 inch HD Kenlowe fan kit to cure the problem, The radiator was duly sent away for a full refurb and to have a high efficiency core fitted , before re-assembly I thoroughly flushed the water system, The new radiator was installed along with new hoses and clips and I finished off by installing the new Kenlowe HD fan kit , All this and she was still running hot Aaaarrrrr..

After lots of head scratching and plenty of the red stuff I eventually decided to go for the Waterpump 'easy job' but not when you shear three of the pump to block bolts!! On removing the old pump I found the impellor had sheared off (fault found at last).

I did manage to drill and tap the bolt holes but with much stress and swearing, when I had finished re-assembly there were no leaks and no running hot.

I only uprated my cooling system from standard because the car will spend time in France and Southern Spain where the ambient temperature is a lot higher. Mick
