Is there an offical method for bleeding?

Is there an officel method for bleeding a diesel?

Apart from squeezing top hose and removing bleed screw by battery box
is there anything else?

Having fitted and removed an FBH I'm sure I've lost more coolant then I've put back.

Can watch temp gauge get to 9'oclock and then drop as I assume inline stat then opens and then temp gauge creeps back up again to 9 o'clock.

Remove the bleed screw, ensure the expansion tank is half full then blow down the hole in the expansion tank until all the air is expelled from the bleed hole.

I hope you realise that statement will incur the wrath of the one who always quotes as follows

"you didn't refill and bleed the cooling system according to the MGR recommended procedure".

Don't say I didn't warn you

Now back to the naughty step for you my lad

Brian

P.S. Ian, Trikey's method works fine in terms of what is lost when fitting a FBH

But on other matters Brian you preach that the manufacturer knows best.

So do tell us, why is this any different?

Because it's not necessary for what Ian wants to achieve Simon, plus I thought I'd have a go at "cut and paste" answers........sound familiar

No. Half full. Half empty is a pessimist. Half full is an optimist. Trikey is an optimist.

I think it is more to do with you having a 1.8 or not

As long as the top small stabbing in the expansion tank is clear and not blocked (where the small hose is connected), with the bleed screw removed they pretty much bleed themselves Ian.

Check the level after a few runs, top up if required and you should be fine.

If you lose coolant on the diesels, the first symptom is lack of heating in the cabin, and that happens well before any movement of the temperature gauge.
