overheating

i have a p reg 306 and my heaters are blowing cold, i have checked the water
and it seems fine except when running the engine with the filler cap off it
is spraying water up, what could be the cause of this problem as i've run out
of ideas!!!

 

Have you looked at your heater matrix?? or it could be a very large air
lock.flush it out with ahose pipe joined to one of the top or bottom
hose on the rad start the engine and just let the water push the air out
also turn heater on and wait to see if that dos the trick.
good luck from chris Addlestone surrey.

 

Have you bled the system?

if by bled you mean removed the plug at the bottom and poured water through
then yes, but now it won't even start it seems to be turning over too easily
as if there is no compression, any ideas??

 

Could be a blocked rad. so remove the rad and give it a good clean
out.you say no compression.remove a spark plug and use a compression
tester. in each plug hole.to see what reading you get from each plug
hole,good luck from chris in Addlestone Surrey
