Refilled it slowly then ran the car at idle with the cap off and kept topping it up until the level dropped no more then replaced cap but lifted bleed valve pin (black bit on top of tank) and let car warm up to running temperature.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi guys, i'm having my header tank changed in a coupleof weeks and i just wondered if it necesary to bleed the entire system after replacement or not. Cheers Chris

POST 2Original post

I didn't with mine. Refilled it slowly then ran the car at idle with the cap off and kept topping it up until the level dropped no more then replaced cap but lifted bleed valve pin (black bit on top of tank) and let car warm up to running temperature. After that revved it every 20 seconds past 5000 rpm until the level dropped no more. Turned off engine and let car cool down then topped up with more coolant. Left the bleed valve upright for the week and the coolant level would drop slightly every day indicating air purging. This stopped after a week and about 100 miles.

This is a source reference. Confirm exact model applicability in the original material.
