Hello i just did the HG runs sweet, but the top hose pressurized and bubbled expansion bottle up. Was i just inpatient when bleeding, i know there will of been a lot of air in system due to hg, i was going to run car for a few weeks then drop coolant to get all the crap out of the system.

I starting bleeding, removed the cap, and removed the Bleed screw on thermostat. bled fine no bubbles. Ran the car, bubbled fluid came up out the filler pipe, did not overheat according to the temp gauge was in middle. Re bled at the thermostat screw fine.

Remove screw from the rad with engine running no fluid came out, turn off engine fluid came out. hmmmmmm. Started back up no fluid came out. Kept bleeding, removed screw from the rad and squeezed the top hose rad end, this allowed be to refill coolant, so it was working, eventually fluid came out even while running. Seems fine at the min need to give it a run but i need to stay in, Ive been "censored" about with it all weekend and i don't wanna annoy my very understanding other half.

I HOPE THAT THERE WAS A BAD AIR LOCK IN THE SYSTEM.

Any ideas welcome because the car is starting to really annoy me lol and im getting close (ive even said it last night) ITS GOING!!!! but i dont want that.

A hot heater doesn't mean your system is clear of air, the heater is fed separately from the main cooling system, it ties in straight off the block and before the thermostat, so you could still have air in the main system to the radiator.
The system in the article is basically the same as the BGB, but with a couple of tweaks. I know quite a few people that use this system and it works, though I have to say occasionally you get a stubborn one that takes a couple of tries to get all the air out.
IMHO the 4AGE is a cracking engine and will take an awful lot of abuse, if you look after it.
Change the oil and filter at least once a year, more often if you are doing high mileages. One other thing it doesn't like is being overheated.
The cooling system is pretty straightforward and very efficient if looked after properly. Neglect it at your peril :wink:
If you want an idea of just how tough and engine it is ...................... Watch this CLICKY

jimi do u know what the part number is for the expansion bottle is the rubber seal is knackered on mine as last night it did it AGAIN drew air in. im going to replace all clips on pipes.
Also do u know the pipe that connects to the bottom of this cap how long should it be? mine reaches the coolant in the bottle between the min and max but its juballe clipped to the cap so im guessing its not the original pipe. Cheers.
