wow,, not good..
with the amount of money at stake now I'd buy a coolant vacumm pump,,
hi all, well finally got the new engine in and plumbed. we filled fluids and gave it a start to run in cam. after 5 mins we had a lot of what looked like steam pushing out of bleeder valve , then top hose started leaking badly, lots of pressure, then reservoir started leaking steam, then fluid. we had a temp gauge and saw top hose was only 80 deg, radiator was in the 20-30 deg at bottom, yet when i took cap off after stopping engine water bubbled out everywhere and made boiling noises. i could not find a temp close to 100 anywhere with laser temp gauge. tried again two or three times with same results...what could i be possibly doing wrong, im really afraid im going to kill it. any help would be appreciated

Damn man after 5 minutes i would not expect that.
Big air lock possible but unlikely. Thermostat failing possible.
Head gasket most likely.
Not the symptoms you want after a fresh rebuild! Not one bit!
Best of luck.
air in system I reckon
cheers

Could even be a water pump i guess.
When you filled the coolant did you keep a gauge on the quantity? Not sure on your radiator size but normally you can calculate pretty accurately how much coolant is required.
Easy way to know if you have an air lock somewhere.
Also when ever i do a first start i never cap it up. Leave the cap off so i can see the water level but also so i can see when the thermostat opens, normally dropping the level and getting warm.
Then once topped up i will put the cap on.
If it was me i would be doing a comp test to satisfy my paranoia then if all good filling it with coolant again and giving it another go.
cheers for info guys, DAMINK, mate iv'e got a mechanic coming tomorrow to fill,pressure test etc just to make sure no air and check hopefully for fumes to count out engine problem. might be best 120 bucks of whole ordeal. other than that it started and ran first go, the eas kicked in and worked perfect, and only engine fault prior to start up was the slow fuel pump but thats because relay was out on previous ignition on to fix eas. fingers crossed.
I've had this on a lot of cars. These days I always crack the top radiator hose to see if the coolant will then gurgle through. The thermostat is most likely preventing you filling the cooling system. With one of my cars I always end up getting the motor upto running temperature... Then you shut it off ......................... and the coolant will then open the thermostat.... and suddenly the damn cooling system is empty. But you can now fill it and bleed it properly as the thermostat is open.
There is supposed to be a one way valve built into most thermostats... there is often a thermostat bypass path as well (this seems to get blocked ... usually by poeple cutting there own gaskets, gasket goo ..... or the fact people never check for it being block).

When mine was doing the same in 5 minutes it was the water pump...couldn't bleed it as it boiled so quickly. Do,you know the history of your pump?

i had the pump off original engine which was cleaned and checked and appeared to be like new. worst case might be that then, still waiting on mechanic to do his bit, next day or so. its definitely getting too hot prior to thermostat opening, which i checked on stove top and found it to be good.
Thanks for idea, its now on check list.
Probably unlikely if it was checked......just a thought as it's exactly the symptoms mine had...
good luck!
