just finished f22 dohc swap into 94 accord!!
problem being with a thermostat in "note thermostat is good have 3 of them each open in bowling water" the lower radiator hose stays cold and top hose gets hot plus heater dont work" have followed all proper ways to blead the system cant seem to get it though...antifreeze gets really hot and bowels but temp guage stays the same temp guage is most likely faulty, rev the engine with cap off blows antifreeze every where

 

sounds like a head gasket or a bad heater core

 

How do you have the thermostat positioned in the housing?



Try removing it completely, this is only to see if coolant will flow. If it doesn't flow, then I would suspect the water pump. Did you happen to replace/check the water pump before you did the swap?

IMO the Timing belt, balance belt, tensioners and water pump should all be replaced before doing any used engine swap.



If the anti freeze blows everywhere with the cap off and high revs. It could very well be the head gasket. Do you see little air bubbles with the cap off at idle? Do a coolant pressure test and see if any coolant ends up in your cylinders.

 

There's a valve near the firewall inside the engine bay. Its hooked by one of the metal wire that is control by your interior heater ****. A heater hose will go to it and connects to it. Turn that valve over and it will let the coolant in which hot air will blow in your interior. They are commonly stuck, so turn that over.

Like this one shown here:



Turn that Heater Valve Arm! I did that on my buddy's new car which was the '95 Accord Wagon and its getting heat afterwards.
