Hi,
Got a '91 9000cs 2.3t and am getting lots of white steam
out the exhaust sometimes at startup (and sometimes not).
Losing coolant, but not oil and both oil and coolant don't seem
cross contaminated. Saab garage say it's the head gasket ...
and if it is it's their responsibility because they've changed it
twice in the last 6 months ... but they say there is a possibility
that it's something else and if so it's my responsibility ...
now ... other than the head being warped, the block being
warped(!) or a blown gasket what else could cause this
phenomenon?
I can see coolant seeping out between the outlet manifold
bolted onto the side of the block, and the connection with the
turbo ... seemingly indicating that coolant is getting into the
cylinders and then being forced out of this gap in the
exhaust ( and presumably through the turbo and out the
back too).
The turbo on the 9000 is water cooled (although not
inter-cooled I believe) ... is it possible that there is some
sort of water leak in the turbo itself which is forcing
water both out the exhaust and also up towards the
exhaust manifold (and hence out of the joint between the
turbo and outlet manifold)? Sometimes the turbo makes a
noticeable kind of buzzing noise ... and there is a crack
in it's casing ... although I get no perceptible decrease
in performance.
Any ideas anyone?
Regards,
Gary Cook.
