I think Dex is fine. My work truck has 155K on it and its been beat and trailoring for 90% of its life. The Dex in that truck does a great job and is still like new. My boss has another Silerado with almost 200K on the original Dexcool and its fine too. Like Boosty said heat kills the gaskets on these cars, so i'd chnage every gasket you can find while you have the motor out.

Find me proven heat damage and I'll buy your gaskets. There is no heat damage. Nylon66 is rated at far higher temperatures than the LIM gaskets are ever exposed to (by independent sources). I hear heat, heat, heat all the time, but have yet to see heat damage on any set of gaskets removed from a car on this Forum unless the car burned or overheated to the point of siezing the bottom end.

http://www.zillamotorsports.com/DEX <--------have you seen this? DEX is ACID. Read the topic in the lounge from today as well.

But the DEX discussion doesn't really belong in this topic, so let'* get back on track, and save the DEX debate for the other General Chat topic.

Well got the new cradle and motor in today, took 5 hours to remove the old engine and put the new one in, not much is hooked up yet but that won't take long. I still need to flush the radiator to get all the old green antifreeze out of it and flush the heater core.

Hope to have the car up and running in a week or so, maybe sooner depending on my motivation.

I would have taken pictures but the wife stole my camera this morning for a wedding she was going to this weekend.

spent another 6 hours stripping the cars down, the wrecked 97 is pretty much a shell now, no interior whatsoever left in it and all the wiring is pulled out up to the firewall, just got to pull the doors apart and fish the harness out of them and unbolt the main harness from the firewall. Bastards at GM decided to make the harness in these cars one fucken piece, no splits in it anywhere, so I had to take the whole car apart completely so I didn't have to cut the harness. Such as life, it will torn out good when finished though. Got a hell of a mess now though, I will post pictures when I can.

motor now in my 93


stripped interior of the 97


dash ripped out on he 93


pile of parts

Oh yeah..BTW.. GM made an octopus that stretches from headlights to tails..

Work is looking really good. It'* come a long way.

On the coolant.. I say use what you want if you maintain it. Wren will tell you dex kills when it turns acidic.. Heck.. I saw gaskets warp/start to fail in 20K with less that 2 years on the Prestone LL. If Dex is bad..then Prestone must be worse...lol

great progress. love the upgrade.

took probally 12 hours total to remove the harness from the 97, I didn't cut any of it and holey crap is it huge, must be over 50lbs of wire in the main harness alone.

Now lets see if we can make sense of this mess. I am going to swap almost the whole harness to the 93 bonneville, As I do not want to tear the car apart completely, I am going to splice the new harness to the old harness from the center of the car back. Means a lot of soldering and time consuming fun.

Here'* a picture of the mess, all the connectors are intact other than the ones to the left headlight and abs module, they were broken in the crash and new ends will have to be attached.

bill warned ya, lol

Haha. I have the whole harness from my old 95. Headlight to taillight. (ok I cheated and cut the fuel pump wires..) I kept it in case I bought a non 94/95 bonnie. I'm so glad I got a 95 agian.
It is definitely like 50 lbs though.

Keep up the good work. Looks awesome.
