bleeding cooling system, 8v & 16v petrol engines

you remove the bottom hose, then fit new clip

Any idea if the Mk 1 diesel is the same? I dont seem to have a bleed screw on my new radiator.

i need to bleed my coolant as i may have air in it. just cant figure out how the silver fastener comes off the botom hose.

it's a 1999 v reg so im assuming its a mk2

help!!!

mash it off with screw driver, after you have been to shop and bought a screw type clip to replace it

Hi all,

just a quick question;

Should the engine be running from the start of this process?? ie turn on engine, fill with water and then bleed??

Thanks in advance for your answer

Del

no of corse not

my heating not working keeps blowing cold air out all the time.any ideas thanks

if the above don't work then your head gasket be gone most probably

Where the hell is the rear bleed screw - is it way at the back near two rubber hoses going into the dash board?

Its the only one I can find that looks like the picture in the photo

But despite all my squeezing - nothing comes out this one - just the top one????

Also this one at the rear is no where near the radiator its behind the engine is this right??

yes

Dave, where can you get them little clip things that need to be replaced?

you replace them with normal hose clips, get them any where

Cool. Cheers fella

will try and get some pics, but on the 1.4 16v MK2B ive been working on, the bleed screw on the heater hose is non existant.
instead it has a rubber hose that goes over the top of the inlet manifold, down the left hand side.. and goes into the radiator about half way up under the minimum and maximum marks.. presumebly to self bleed itself.

My Punto N reg was overheating and I realized the radiator was empty. I've filled it up and the car stopped the overheating. 1 week later it started overheating again and for my surprise the radiator was almost empty again. Then I took the car to a garage and they changed the water pump and cam belt. When I got the car back it wasn't overheating anymore but 2 weeks later when the weather got really cold I tried to use the heater and my heating wasn't working anymore. I've checked the the radiator coolant level again and it was quite empty again (under the minimum level). Then I've followed this tutorial, filled the radiator to the top (Exact 3L of coolant) , opened both bleeding screws, turned engine on, then waited it to bleed a bit and closed it again. Then I've turned on the heater and yes it started working perfectly again. I'll just keep an eye on my coolant level from now on because I don't know if it came from the garage on a low level or if it got empty since the car came from the garage (I don't know if they filled the radiator up with coolant after the change of water pump+cam belt) and I hope it stills full otherwise the car will have to go back to the garage
Thanks so much for this tutorial, is really easy to follow and works like a charm, I'm a female and I did it in about 20 min.
