just got the valver back its now leak free...however the water temp seems to permanantly sit on the 2/3rds mark, even travelling at 30mph or so. it always used to sit 1/2 way b4 and creep upto 2/3rds just in traffic. When i was sitting in traffic for a couple of mins it was halfway between the 2/3 and top mark and still going! I switched the engine off out of fear. Is this normal? And what can i do to sort it out? Cheers
