Thread: New Cylinder Head

Almost there. Just need the 90* barb for the heater bypass and for my power steering pump bolts to arrive. Everything else is in. Tonight my friend is coming here with one of those air/water flushing things to clean out loose gunk from cooling system. Then coolant and PS fluid bleed and good to go.

The ones i had were actually made of metal. Black in colour. So they will do.

no like this one...

Close to finish. just need to do the heater bypass tonight and trim some of the new coolant pipes + put on pulleys and serpentine and should hopefully be starting it tonight. after a cooling system pressure flush.

new PS hoses, oil cooler hoses too. need to fill PS reservoir and bleed that too. Basically, apart from the block, the cooling system is completely new.

Got everything on tonight. Filled all the fluids. Turned engine over few times by hand and then cranked it with starter.

Then started properly and after a few cranks it started. Everything was smooth and running nicely. After a minute or so went to take it for test drive and within 50m of my house the temp gauge was already moving up fast, so turned around straight home and shut it down.

Head feels hot for 3mins of operation. Top hose was warm, all the heater hoses were hot bottom radiator cold, expansion tank coolish.

Seems water is moving through some pipes but not through head.

Like I mentioned, the whole cooling system is brand new. Even if there was air trapped in the system it would not cause car to heat up so quickly, almost as if running dry.

Supposed to take guests to Margaret river tomorrow, please help!

Uhmmmmmm,

After 50 meters?>????? I don't think that normal operating can heat engine up to the point where needle starts rising after 50 meters. I hope I'm wrong, but maybe some compression is escaping to coolant causing it to heat up that quick? Is there excessive pressure in the cooling system? try starting it up without expansion tank cap and see if you have bubbles coming out. I can't think of anything else heating engine that quick. Hose temps indicate that things are warming up but thermostat is not open.

thermostat not opening, cooling system not bled up correctly would be my opening thoughts.

do the coke bottle bleed see what the system is actually doing.
