Coolant change

[mark123]

I've never managed to get it to take more than 4.5 litres to fill and it's supposed to take 7 litres.

I remove the bottom hose at the radiator, the heater hose where it enters the thermostat housing and the bleed screw.

What am I missing? I don't have an air lock so don't bother suggesting it.

if i rememberrightly i connected mine all up again started the engine and the level dropped drastically so thats when i put the rest of the fluid in...hope that helps

This is the second time I've done it and the level didn't drop in 60k miles.

Might you have a blockage somewhere in the rad?

i think mine only took about 5.5l, although i removed the thermostat to flush the block when i did mine - quite a lot of coolant was released from behind the stat housing. may be the 7l's just an overquote?

you'd need a gasket for the stat housing if you remove it - *think* it's 8200267272

or is there a drain plug for the block? perhaps mine's now 5.5l coolant:1.5l tap water

ed. twigged - presumably the rest is in the heater matrix circuit
