Cooling issue

[Shug]

Probably not, but I'd like to go through the motions of clutching at every straw I can before accepting the inevitable

I had a leaking bleed valve on the top coolant rail (Old S1) and that was a pain as it didn't leak coolant, but as the system cooled it drew in air. I bled the bastid for ages and kept getting air until I figured it out. The thread was buggered so I used miles of PTFE been ok for about a year.... (Touches wood!)

Shug, i've got a gas sniffer if you'd like to rule out nastiness... It gave rdh some good news recently

[Shug]

Aye - will replace my header tank and maybe get that off you sometime dude

[Shug]

Okay - wee update... Expansion bottle certainly cracked so new one on order. Had a sniff inside, no whiff of exhaust fumes. Water level was low (actually inside the tube at the bottom of the expansion bottle) but it's lost water consistently for years - matrix leak - and it's been sitting. So that's not out of the ordinary.

Will put on new expansion bottle, bleed the whole system like a b*stard (prolly flush through new coolant) and see if it repeats. Then sniffer test if needed...

Name an egyptian river? De-Nile

[Shug]

Maybe. Maybe not.

Would rather do the easy stuff before ripping the engine in 2, n'est pas?

I'd be clutching at as many straws as I could if it was me

Rad weld the matrix then drain and flush, fit the new bottle and cap, jobs a turnip.

/pikey fix.

Don't waste money on 10L of clean coolant - you'll need that when you do the head gasket Do the sniffer test first.

Cheers,

Positive news... Sealed the crack in the header tank and topped up & bled the coolant. Not a twitch on the run to Brighouse Bay. It got up as far as 92 when sitting idling after some pacey action, but that's fine. Rock solid for 2 days. Will keep an eye, but the level in the expansion tank was really low, so it might have sucked through an air bubble. Will still do a sniffer test when my new header tank arrives.

Might now get my thumb out and redweld the matrix - it can only be a tiny leak, so it should work...

demisterman (ebay shop) sells new ones for £57 (delivered)

[Rich H]

Aren't they the same as a black cab or some such?

[Baggy]

Think so.
