Water system on a v8

mordzy · May 5, 2014

Ok, on engine cranking I'm not getting any water rushing back into the bottle so thinking it's possibly wrong. Maybe why the old engine was ruined from the previous owner.

I'm just cranking it over at the moment. Have a look at the pic. Is anything wrong?https://www.dropbox.com/s/qllzwki9hk5trom/Photo%2005-05-2014%2008%2058%2032.jpg

If water rushed back into the bottle on cranking you would have a problem, start it up, fill the system and make sure it is bled through. then run it up to temp and make sure the stat opens.

Ok. Realised I had the two small connectors backwards. One from center of manifold is for air locks. Usually blocked off. The top one goes back to the bottle. .

I guess injust wanted to make sure the pump was functioning. How can I make sure the stat opens?

Check the bottom hose gets hot and keep an eye on the temp gauge. I don't like fans mounted on the radiator core, I have seen them damage the core on off roaders.

The large pipe that goes to the intake manifold gets warm close to the manifold. Bottom large pipe is cold.

I think I sorted it.

Left her running for 5-10 mins. Large pipe from top to top or rad get warm first.
Rad gets warm.
Bottom larger pipe gets warm last.

Stat doesn't come on because there ain't one. Prev owner rigged a switch in the dash. I'll get a stat and make sure it trips the fans.

Good o, Have you refitted the crankcase breather pipes and flame traps and the float chamber overflow pipes.
