2.3 or its sister the 2.4 dohc gm. Absolute garbage engines, but a tip on a water pump change. Just pull the exhaust manifold. Then you can reach right down and pull the nuts on timing cover to slide the whole assembly of the cover. No need to take the chain off or anything like that. Much easier than trying to fight from the bottom even on a lift.
Another trick. Or maybe common sense. Certain vehicles, its much easier to pull the cab i.e. ford....or even entire body like Chevy cargo vans like the express or even a trailblazer, envoy to do any major engine work like head gaskets, engine jobs, etc.
Lets see...**** I have ton's, but not coming to me. Oh last tip. It may seem silly to some, but if you have a lift, then by all means pull the trans on rwd or 4wd trucks, if pulling the engine. Sometimes its a helluva lot easier to pull the trans first, then pull, then engine, then reverse.
This way your not fighting from top to line up the bell. This is especially useful on like s10s, blazers, or even a KIA sportage that I did recently, where there is minimal floor clearance to pull the bell bolts.
The best tip of all is study for like 5-10 minutes whatever your doing. Look at every bolt, wire, etc. Run pictures through your mind of it coming apart and you will be able to figure out what is necessary and not necessary to touch.
And last tip is do whatever is comfortable or easiest for you. Speed will come with time and experience. There are probably hundreds of ways to do one job, but everyone has a way they like that is comfortable and allows us to hammer through.
Oh and last advise. Definitely test drive and then re hoist check anything major done. Study every last bolt and any leaks to ensure no comebacks. Comebacks can be a life altering experience as in the case of someone that did some jail time I knew. He forgot to tighten the 4 corner bolts on the subframe of a gm and lets say the customer almost died when the motor/trans went a different way than she was turning.
