HI PEOPLE PLEASE HELP!!
engine conversion from 1700ky to 1900 1y all in and running great but....
running up and trying to bleed cooling system, heating nice warm, parked it up hill
radiator stone cold, opened bleed valve on radiator to release air...still not warm!!???
help and advice please

What type of thermo stat you got fitted? Wax type or bellows? I'm sure If they fail it's in the closed posistion.

not sure wot type, used what was in 1y as i converted
could thermostat cause this then?
pipe from stat is hot thou

have you changed the water pump belt.
the diesel engines have 2 different types of water pump .
they look the same but are designed to pump water when the pulley is spun different ways. if you have shortened the belt make sure its turning the same way it originally did!

these will happily bleed on flat ground , if not there is a fault with the system.

how long was it running for as they may take quite a while to warm up!

thanks for that billy

i havent shortend any belts just used 1y set up wiv v belt and have no power steer

unsure ive let it get hot enuf thou....running for appox 2o mins and guage just a tad over half way

just how hot should it get before stat opens?

radiator bleeds fine but not hot water and rad not getting warm

will it help to run it round abit? carnt go far becus not road legal but have run it up and down road

heater blowing nice and hot

scared of overheating and causing damage

waterpump is brand new

ANY IDEAS WHAT TO TRY NEXT PEOPLE!!??

THANKS

yes but which pump did you fit?
is it the correct one for the direction you need.
they look and fit exactly the same except the impeller is reversed!
so will only pump one way

I had this problem about a year ago when i got my van trailered to me. Turned out it just needed a proper bleed, i followed the brickyard how to and it was fine after that. Basically need some one to really rev the engine once its up to temp, if you then look at the coolant tank you should see the water level drop. Remove lid and top up with water, just keep on doing that until the rad gets hot. I was convinced my rad was blocked until i tried this
