Coolant system problems

[ben_r1]

Fitted some silicone hose yesterday and had some trouble bleeding the system but think i did it correct.

But now i have a slushing noise coming from behind the dash whenever i start the car from cold.

Can anyone confirm on the correct bleeding sequence, its a 197 but i'd imagine its the same for the mk2's aswell.

(and can anyone with a 197 confirm for me which side the hose with the bleed screw goes into the bulkhead, i got mine closest to battery atm but think its wrong)

Cheers all

I usually do the following...

Bottom hose off the rad, drain system.
Reconnect hose
refil system
run engine with bleed valve open
close bleed valve
refil system
run engine and top as as required

Yeah thats exactly what i've done, but this very irritating slushing noise persists...

Its coming from the heater matrix, but it stops when the engines warm and heaters work fine. this ones got me confused lol

have you let the car warm up until the fan kicks in?

 

[ben_r1]

2 or 3 times yeah, then let it cool down start it again and theres the annoying water fall behind my dash again

hmmm, take the hose off that goes into the heater matrix, put a hose pipe on a flush the air lock out?

 

[ben_r1]

is it definately an airlock then? took the car on an hour drive yesterday and it didnt overheat

 

[ben_p]

sounds like one, but hard to tell without seeing it!

i had it running with the bleed valve open until i got an air free stream coming out.

Will try bleeding it again and if that dont work i'll sell it lol
