i have a cheap alloy one, its CA or SR, not sure, looked like it would fit, guy i got it off said it leaked around the top edge of the funnel section where the radiator cap goes in.... but that doesnt make any sense cause thats not where the cap seals
if you keen i can go look which type, im not gonna use it

im reluctant to give it to you, cause i think they are absolute crap. And i cant believe how heavy they are... a good few kilos heavier than plastic tank alloy core

Are they seriously that bad??? Wonder why every one raves bout them then??? Might just put a cooling system cleaner through and remove rad to back flush it. Can trim rad cowling more at same time if weather holds out.
Then retest. Still debating if 1 12inch or 2 10inch fans....

FROM DAVIESCRAIG WEBSITE:
Question No. 4 Is there any advantage to having two slightly smaller fans as opposed to the one larger fan? One of the very important factors with engine cooling fan/s is the volume of air any specific Thermatic Fan can pull or push through a radiator. In general terms 2 x 14" fans will match the volume flow of 1 x 16” fan but not 2 x 12" fans. There are other factors including core thickness and clearly the thicker the radiator core a more powerful fan is required. Therefore a single 16” fan will out-perform 2 x 12” fans in almost all situations. E.G. If your radiator is 4 core or greater then 2 x 12" fans wouldn't be recommended. Therefore 1 x 16" fan could be sufficient. Remembering that any Thermatic Fan will cease to be effective once the vehicle speed has reached 50-60 KPH after which the ram air takes over. We also recommend Thermatic fans be fitted to the downstream (engine side) of the radiator

looks like at the same pressure 10inch is 270 where 12 inch is about 350, so for pure flow two tens could be better still say your pissing in the wind without having your rad rodded, even if its $200 better than the $2000 and prob 40hrs i just spent rebuilding claires head and bottom end cause it cooked itself flushing it with the hose is pointless

Will try first, need to trim the panel more, it's only in stop start city I worry which is under 60kmh as mentioned.
While it's out will talk to rad places. Might be worth trying to find copper core and tank rad to replace. Twin core could be better if find at right price. Like don says, try the easy things first ;)
