Went for good 1hour n half drive,hit some traffic ,hit some traffic lights,no temp raise ....got home ,Sat on idle for good 20mins...just about to get out and thought I'd stay for 5more mins...and temp gauge started to climb just before red....all hoses were hot as they should be ...but fan looks like it wasn't doing it's job,I'm going to take it.back to island 4x4 and hopefully change it ....I thought it would have more kick as the temp was just before red ....with engine off I can turn it with only slight resistance,goes round maybe 7inches or so when u grab blade and free turn it....��unhappy bunny cost me 118quid ...I'm going to put some self tappers in my old fan ,and go for same drive tomorrow before I take it back ,just to be sure ...I heard 2screws in front face of fan should lock it in fast position...so running cool all the time ....
DO NOT lock the fan. Fan locks by centrifugal force acting on the fluid in it. So you will be able to turn it with engine stopped even when hot.
