[fura]

Hope somebody will find these tips usefull 8)

1. OEM Saab thermostats are manufactured by Motorad. So if Motorad thermostats are available at your local autoparts shop, it's should be possible to get OEM quality thermostat at lower price (of course thermostats from Saab are not very expensive too :wink: ).

2. If engine temperature gauge starts behaving strangely and indicates hot running engine it doesn't necesserily mean that you've got cooling problem (like thermostat failure).
Check how the temperature gauge reacts to electric load - if it jumps when turning on/off the lights, ventilation fan or rear window defroster, then you've got electric gremlin
Check temperature sensor connectors at thermostat housing for corosion and clean them by pluging/unpluging a few times. Also check ground points in engine bay for corosion and lose ends. This should fix your "hot" engine :wink:
