how hard is it to bleed a coolant system on a frst

it's doing my head in

the temp gauge is in the red

which is the best way to get rid
of air from the coolant system

 

Is it not an underlying problem elsewhere? Blocked rad? stuck thermostat? cracked header tank? or worse head gasket? any more info?

 

yeah sorry

i should of explained more

i put new piston rings in, so basiclly a rebuilt on the engine, with
new gaskets etc also brand new cylinder head ( all proper ford parts)also it;s just had a new theromstat
there is loads of air but i was running it for about 20 mins and still shit

 

 

How are you bleeding it?

 

holding the revs at 3000rpm to bleed it.

thats what i do at work with newer cars.
ive not worked on an old car like mine before
do you do it diffrent or somthing?

 

Personally. So I dont know specifically to your car.

Start from COLD
Fill system to the mark on the bottle.
Squeeze all the coolant hoses to try and shift the air around.
fill to the level again.
Repeat a couple of times
Start the car with the cap off.
Leave it idling
Engine will take in a fair amount of the coolant down into the block.
Keep the level on or slightly above the mark on the bottle.
Run the engine (idling) until the fan cuts in and out a few times.
Make sure the bottle doesnt run dry. Or you'll ahve to start again
Leave it to cool.
Check the strength of the coolant
Bung the cap on and take it for a quick drive.

Any Good

 

i will try thanks

 

also turn the heaters on hot and turn the speed on full this will help circulate the water and remove the air

 

Wanna explain how? Heater Matrix doesnt have a Hot/Cold valve afaik

 

Always been told and ppl have said on here it helps to move the water around and remove the air

 

On old cars. Like 50s/60s cars then yeah Id go with that. Not on modern cars. Basically the matrix is the same temp as the engine ALL the time.

HTH

 

yeah basically leave the header cap tank off when idling.

 

ok
