Hi newbie here, so far great forum. i just bought a '91 camry 6cyl. automatic. she has 143,000 miles on her. got her for $700.00 i think i got a great deal, the car runs smooth no dents no rust nice interior, everything works fine. my questioin is this: im doing all the general stuff, such as oil changes, filters, flushes, plugs, gen tuneup stuff, gotta get new tires. i'm trying to do a radiator flush and i can seem to fing the petcock valve to drain, can someone post a pic or show me where its at? i cant seem to find it under the rad anywhere. also where the heck are the other 3 plug, and is it difficult to get to them? and lastly, my camry has pwer locks...when i get out of the car and hit the lock button before closing the door, they unlock by themselves. i press down and they pop up again, finally i lock the driver door with key and they all lock. do i have to do this all the time? cant i just press the lock button and have em all lock then close door? hope you can help me out with these minor items, thanks in advance guys.
