Hi, this is my first post here. I am a total rookie when it comes to repairing cars. My 18 year old son has purchased a 1970 Buick GS last year. He is off to college and has left the car here at the house. Luckily he left the keys with me and I get to drive it and love it. I need some advice on where to get a repair manual for this car that is in language I understand. I have the shop manual for it but was wondering if there is a manual by Chilton's or Haynes. I have looked on line and it doesn't look like they have anything. I got an online edition from Haynes that is terrible. I need to replace the water pump on it and suspect I have to remove the radiator and fan shroud to get to it. If this is true is this something a newbie could handle? I do a lot of diy building and woodworking but have never gotten into cars, always wanted to, just never did. He is coming home for a few days next week and we would like to tackle this if you think it is something that would be doable for a beginner. I wasn't sure if this is the right forum or not. Thank you all for any help.

No need to remove the radiator for the water pump. I do suggest removing the fan shroud though to make room to work... Find some penatrating oil and spray it on the bolts ahead of time and let it soak in. The brand PB blaster works relly well.... Use a small hammer to tap the bolts a few times before you try to remove them and be patient when removing them as they often break off. Also be sure that your socket set is in good condition and makes a good grip on the bolt or they can strip easily. Another tip is the buy a complete gasket kit for the engine, not just a water pump gasket. Eventually you will use most if not all of the gaskets so it is nice to have them on hand.... Also you will notice that some of the bolts need thread sealer on them so be sure to clean the bolts well and seal them when you re-install the waterpump.. I prefer the "right stuff" brand name of sealant for gaskets that need extra sealant, it works great!\ Oh, and protect the radiator with a peice of cardboard or something so that you do nto damage it while wrenching.... My final tip is to air down the front tires if you have a compressor to pump them back up.... This makes it easier to reach under the hood from the front.... Oh and make sure you have adequate lighting, music and beer....
Thank you so much, your advice really helped. I did snap two of the smaller bolts holding the water pump on. They were very rusty. Any advice on removing those. Removing the shroud really helped. Again thank you for your help. Dave
Heat with a mapp tank and a set of easy outs. I have had good luck with reverse drill bits PB Blaster and heat take your time.
Worst case if you can not get the old bolts out take the cover to a local machine shop and have them get them out for you...
I've taken them out with welding a nut to what's left of the stud. You do have to watch how hot you get it. Worked every time for me. You can do this with the timing cover still on the car or take it ll of the way out. Anyother way had taken me forever and not too successfull.
Good point, since the timing cover is still on the car it would be nice to avoid removing it. I have also had good luck with drilling the old bolt out and then using a "helicoil".
And, I may add: A **** load of good tools, lots of mechanical aptitude, and tons of patience. Good to go:TU:
Thank you for helping me. I was able to heat them(wife thought I was going to burn the garage down! Made the kids leave!) and back them out with an easy out. One more question and hopefully I will leave you all alone for a while. I am having a hard time finding a replacement set of bolts for the water pump. Do you all have any suggestions? Thanks Dave
Local hardware store should have the short ones. Maybe the long ones too...Small ones are 1/4 nc, alt bracket bolt is 5/16 nc. Bring the old ones with you to match up the lengths.
