I like the factory radio with the CD player. If you're looking for aftermarket, go to http://www.crutchfield.com/ They have installation kits too.
Go with the names you know. I put Prestone in mine. No problems.
5w30 Your brand. Most are all the same
Your best bet is to get a Chilton's or Haynes manual at Amazon.com or eBay. They have complete details.
Probably around 16 mpg. I had a 1969 LeSabre once and the best I got out of it was 18.6 on the freeway.
The question you should be asking yourself is is this car still worth it?, not to put you down but an enging swap is at best of times labour intensive and expensive.
Your best bet is a GM dealer's service center. If nothing else, you can get the part number and do an internet search. Try gmpartsdirect.com .
go to BEST BUT and spend 69.99
If you have replaced the thermostat already, and the radiator is flowing properly, I hate to tell you, but the quad 4 has a nasty reputation of cracking heads around the exhaust seats. Be very careful in getting this repaired; make sure the shop that does it has had experience with this motor.

I owned this car is high school and the most I ever got per mile was 12 miles per gallon. City driving netted around 8 miles per gallon at best. This is not the best car if you are trying to conserve on gas.
Best bet would a factory service manual, or Chilton or ?? I retired in 1994, sorry I can't help
it means it cant read the CD mine did that every now and then it might work ur best bet is to get a new radio
