Hello to all!

I just bought a 1997 sr with 230k. I paid $300.00

Known issues are :
Overheating (unknown reason. I have not attempted to replicate for fear of further damage)
Drivers side seat (electric) will move forward but not back
Pass rear window not working
Everything else is working very well imo

My plan:
Drop off at shop to check heads and gasket - replace if needed
Replace timing belt and Waterpump w full kit
Replace thermostat
Change fluid in all diffs and transfer case along with transmission

I'm very open to any other suggested maintainance. My sr did not come with the owners manual ( any online?)

The plan is to daily drive and 4x4 weekends. I'm moving to Fort Collins, Co from LA in sept (if any of you are from that area)

I'm hoping to stay under $1500 in repairs (found used heads online pretty cheap if needed)

Thanks for all the help!
