Hi all

Ok so new radiator
new temp sensor genuine
wiring checked all good
new thermostat 82 degrees not 87 as standard
antifreeze
wetter water
deionised water

so on a long run temp so long as im moving say 30mph engine is fine
temp reading half way
however slow and the guage creeps up then goes off the scale
Engine does run hot but as do all tover v8
as soon as im moving temp drop in seconds back to say 3/4
viscus fan running flat out
wetter water drops temp byt 20 degrees

so me thinks air lock some where
heater throwing hot air no problem
top up tank full

if i throw the car fast into a bend again the temp guage goes straight of the scale then almost immediately drops back down to 3/4

so air lock i presume but cant get any more in the system

any tips on how to chake this irritation?
