Hi everybody this is my first time on your forum I hope somebody can help me I have a 2000 v8 disco 2 and ,i am having a few problems,I have tested my heads,they're good,but it is still pressurising and running hot,so fitted new thermostat,stille preassurising,but only on top half,the top of my stat gets hot halfway down but the bottom hose running off it stays cold,is this because the new stat is not working or is there some thing I have missed,is this a common fault maybe,thanks guys,
regards Dave

Dave,
How did you test your heads?
How many miles on the truck?
Have you bled all the air out of the engine?
Does your heater run cool or cold at an idle?

two words, air pocket

you need to remove all the air out of your cooling system...(bleeding the system)
