Looks like time to the marigolds out!

Looks like time to the marigolds out!

There must be a lot of mud and crap in there if you've got marigolds!

Dad was the one who did the thermostat / bled the system. I just checked with him and he said he only opened the top one?

You open the one at the top of the radiator and the one on the heater pipe, Fill very slowly until it starts to flows out of the radiator, close the radiator bleed screw, continue untill it flows out of the heater tube and close bleed valve, take it for a spin, open the bleed on the heater tube, slowly untill it just starts to hiss, wait until liquid comes out. Tighten and wait until it's cooled down, remove the radiator and top up the coolant if necessary

There very simple cars to bleed as long as you don't fill them too quickly, there's a one way valve built into the thermostat, so should self bleed fairly quickly


If it's been bleed properly, and If you can here bubbles circulating on first start up there's almost certainly something, low coolant level, air being sucked being the most common


I take it the noise is since the thermostat change

Yes, didn't have the noise before changing the thermostat.

Bubbles or sloshing

Bubbles or sloshing

A sort of burbling, like water running through something on start up. To be fair, it stops pretty much as soon as you set off. It's why I wondered if it was just water caught I the scuttle and the start up vibrations were dislodging it.

Yep. It's as you turn the key and it kicks into life.

Bubbles circulating before and after the thermostat change

Sounds more like

Air being suck via a small leak

Any pink staining anywhere

Or

Gasses being add

Any loss of power, knocking noise under acceleration, especially when cold

Any scum in the expansion tank

Had this a few times from weeping core plugs and loose hose clamps

Is there is a small loss of fluid as well

Haven't seen any staining.
Will try bleeding again, and cleaning out those duck bills. New MAP sensor has been ordered, so will take a closer look when we fit it, to see if we can see any issues with pipework, etc.
Fingers crossed we can get it sorted by later next week otherwise I won't be able to go to work!
