Hi All
Since I’ve started to use my C Cab van more frequently I’ve noticed that it seems to run very hot. As mentioned in another post I decided to fit a capillary gauge to check the temperature (there was a handy boss already present in the header tank).
Well the average running temperature was around 90 degrees. Any hill or putting my foot down sent the gauge up to 100 and on a 1 in 5 near us the rad boiled. I checked the capillary gauge by comparing it with a glass alcohol gauge and it’s accurate.
The engine is one I rebuilt about 2 years ago as a spare. It was thoroughly cleaned and now has a brand new Ricardo head. Both hoses are new and the bottom one not pinched by the dynamo. Just to check I took the side branch off and it was all clean as a whistle.
The radiator is a period honeycomb one of unknown vintage so I used a can of Holts Speedflush yesterday evening. It still runs hot!
I don’t want to replace the honeycomb rad which I think is probably the problem. So I’m contemplating a four blade fan.
My question is how much more cooling do you get from a four blade over a two blade?
Cheers
Howard
