details? why did you replace the engine?

 

[slowNstdy]

And what is it?

 

[kwmnh]

its an 03 disco II, i replace the engine cause the other one had a rod go through the oil pan .

 

[slowNstdy]

wow thru the oil pan? good times! did you burp the coolant system?

 

[kwmnh]

yep, the hose below the thermostat always stay cold though, all the other ones are hot and full with coolant...im thinking it the compressed air from blown head gasket preventing the thermostat to open....or am i wrong?

 

[slowNstdy]

did you replace the thermostat? i would start with the cheapest possible fix first! it very well could be HG. do you know anything about the engine you installed?

 

[kwmnh]

engine with 83K, has good compression...
is there any other reason the water wont circulate ?
can i find that thermostat in auto part or only dealer ?
Thanks,
Leo

Those thermos can be hit/miss on if they actually work. Search for "in-line thermostat" for more info

Edit: I'm not saying this is your issue (too many other things to rule out). But, did the search for ya:

Did you hook the thermostat up backwards?

 

[kwmnh]

thermostat hooked right.
