1997 900 SE turbo overheating

hi all,



am a newbie owner of a '97 900se turbo hatchback 5dr. Car's been running fine so far but coupla days ago I noticed that coolant had leaked. Found that coolant was leaking from the heater core box so cut the coolant hoses leading to the heater core and joined the 2 lines together using a connector. (Don't need the heater anyway......am in Florida). Refilled the coolant but found that engine still overheating although coolant level is upto the mark. Purged the system for a long time till I got no bubbles coming out from the coolant tank. Cannot figure out if its the thermostat or the coolant circulation. Please help. Any input will be appreciated.



Thanks all, Biki

The most popular reason on this motor would be the water pump bearings gone bad and the belt then slipping, or something else in the serpentine belt causing it to slip.

Move the upper idler pulley to the "slack" position with a 1/2" drive, lock it in place through the lock hole. Check out the pulley by grabbing it and wiggling. One that is bad will have noticeable play. You can usually spot them wobbling when running.

If it is the WP, then replace the thermostat while you have it drained down. Cheap and easy. Also, replace the serpentine belt and the upper idler pulley unless it's been done in the last 50K miles.
