Yes, thanks for the encouragement MB, - yeah brand new clutch fan out the box, grumpy cause I can get a clutch fan on EBAY for about $80 and I paid $190 - what's the world coming to?

I am not sure how a clutch fan works, perhaps it needs to get hot first ( to make it engage ? )

I was looking on youtube and noticed that some people wash out the engine with muriatic acid ( hydrochloric acid for pools) - I was thinking of doing this to before replacing the hoses, water pump, clamps and fan belts, this will make sure the engine head is perfectly clean? what do you think?
