Accelerating Away
Old Ford fiesta one or similar . You can buy the radiator hose sensor off eBay for not much money, way cheaper than Kenlowe and eases load on yer waterpump which don't seem to last long these days .... ( 3 Brit part ones in 20 years )That sounds like a good idea. I've got to make up some shrouding for this one anyway so I might as well put the work into a more efficient fan. Thanks for the tip.
