Original body style, another name for the GMT400 series
That sounds right, suburban second door windows go all the way down, and these doors are straight sided.
The radiator on these is aluminum core with plastic tanks. There are gaskets between the tanks and the core that shrink with age, and if you've had much of a front impact that also makes them leak. And Chevys do eat water pumps. Replaced the one on my 99 vortec 5.7 this time last year, was the original one with 165,000 on it. The radiator isn't too hard to replace, l could've done it on my truck 2 years ago but didn't have the time. The shop that did the job only had the truck a couple of hours. Most things on these trucks are fairly easy to fix....good luck with your truck
Another good reason to replace the cap and rotor: they can be damaged that you can't see and it can make a misfire. My truck had this problem and it ended up ruining the flywheel and busting the starter because it was trying to fire 2 cylinders at once. If you can get them, go for a cap with brass contacts instead of the aluminum ones, it will last a lot longer
Don't know about a 95 but on my old 99 Burb l had to pull the motor mount bolts out and jack the motor up ,just a couple of inches. The pan has a windage tray in it and there's a baffle plate mounted on the main bearing caps. These will get tangled up with each other if there's not enough clearance. (Ask me how I know! )And it was a 2wd. There's just not a lot of room down there...
Check out the pcv valve, if they are bad they can suck oil out of the crankcase
What year truck? Throttle position sensor and idle air control valve can act that way
On vortec 's if you replace the idle air control valve also replace the throttle position sensor unless it was just replaced. They often go out together
