Coolant bleeding procedure
#1
Please excuse if it's written up already
I have searched but kind of confused with all the different ways

Ok so what is the proper coolant bleeding procedure
On a 2002 1.4 with ac.

(1) I have found a bleed screw on the firewall heater matrix which has a tyre like valve cover

(2) bleed screw on the thermostat

(3) that stupid black bleed screw on the top of the radiator which I cannot lock down.

Could someone please explain in sequence
Which bleed screw to start with.
I have read I need to Jack the left side front wheel as high as possible. For what reason I don't understand.

Yes I'm a woman in heels but I like to do things my self LOL

Start with the lowest and go up to the highest so your last one will be the one on the bulkhead or fire wall as you say.

How high are the heels - no only joking far play for doing things yourself

Hi and thankyou for your help.

So
Radiator bleed screw
Then thermostat
Then finally the heater matrix.

Most of my friends say I can't fix cars but done ok so far.

Hi Maria yes you are spot on on the bleed process - remember to run it up with the header tank cap off to allow for any air to come out, when it gets hot put the cap on. Best to leave over night and recheck the level in the morning.

STOP.The 'car tyre' type valve by the firewall is probably the A/C.Is it on a large metal tube,about 3/8"?

No it will be the coolant bleed and even if she did get it wrong and unscrew the air con one (and i doubt that as she seems to be well switched on) its only a dust cap and no gas will be released  Wink
