right i changed the theromstat back in november for a new one as it was jammed open.
astra with z18xe engine
now iv got some cooling problems that started a few days ago.
car does get up to temperature but takes a while. ( up to about 85 degrees) could take 15-20 minutes which is twice as long as it normally takes.
then randomly when im on the move the temperature just goes down to less than 80 degrees and wont come back up to normal temperature until im sat at traffic lights.
a) have i bought a dodgy stat?
b) could it be the temperature sensor on the stat housing?
i bought my thermostat from kevin cooper in plymouth. dont know if anyon else has had issues with their stats?
help appreciated thanks
