I guess that is an old name for it! No I didnt work in a dealership, but you're right, that was the name of it back in the 90's when I started doing TPI swaps, and I guess the name just stuck in my brain!

To the OP, the temp sensor for the mirror looks like this.

Thanks. I just found it. Glad I didn't butchered any of that front stuff. So I am going to trace the wires as I can see they go all the way into the green block for the front light harness and pull them. Once I get ready for install I am sure I will have questions. Thanks again.

[Lost81c10]

Are there any wires that I need to find/trace from the engine wire harness to the Fuel pump/Tank? I have not seen or have not been able to locate any so I wanted to make sure. I will be pulling the engine out tomorrow but didn't want to get caught in the middle because wires are still attached to that. I see that that this harness goes straight to the back on the driver side and I am thinking that this is where the pump might be connected to but none of these wires are tied to the engine harness. I was assuming that the pump harness would be part of the engine harness but maybe totally wrong. thanks.

anything yellow plastic, yes is airbag related. That connector/sensor you show is the 'crash sensor' that mounts couple places up front and signals to the main module to set off airbags in event of a impact.
yellow is reserved for safety related connectors, on all makes fyi


Thanks for the pics, that is what I needed BTW

[71cadc10]

yes I 2nd the trans...that is normal accumulation of fine metallic on the magnet.
clean pan, filter, fresh dex VI, good to go.

for pulling, I usually use the upper most, inner bolts...so that the chain doesn't damage the valve covers.
it doesn't look like a whole lot of aluminum there around the bolt holes...but they are plenty strong. I use the bolts like you have there, if they are threaded in with engaged thread of ~ 1" should be fine.

[Lost81c10]

Well they are finally out and it feels good. now the fun begins, and all the questions.

I ended up going to lowes and getting some bolts to use instead of using the originals. I just didn't want to damaged any of them.

[Lost81c10]

This was one of the casualties. I don't even know what it is. So what do I need to be looking for and is it expensive?

[Lost81c10]

Some more questions before the donor goes to crap metal:

Do I need the donor Throttle cable or will I be using my 85 cable?

what about the transmission shifting cable or any part of it from the donor, do I need to keep to use?

do I need to keep any part of the exhaust after the Y?

This last one is just something that I just thought about looking at the donor engine bay, what about brake master and booster, are any of these two of any use/benefit and easily adaptable to the truck?

thanks.

Can't answer any of your questions exactly. Mine is DBW. I'd save it just in case. I also went to some trouble to get the entire transmission shift cable which required dash dissassembly to get to the back of the column to disconnect it. I'll be replacing the column so not sure how it will work out.

I tossed the whole exhaust. The muffler was the size of a VW bug.

I also upgraded the brakes on mine already. I assume the booster and master could be made to work or was of some value to somebody else.

I probably kept too much. I still have a pile of parts I'm trying to sell....

if you change the oil pump keep in mind that the new one has to be shimmed..
most gaskets on a LS can be reused..so if it aint leaking id leave em alone...
if you look at at the timing change itll be loose..if you put a new one on itll be loose as well..
my 99 z71 had 285000 on it when I sold it 6 yrs ago....the guy that bought it is still driving it...only thing on the engine thats been changed is the water pump
if your worried about the oil on the valves then new valve seals are a simple swap...easy to do it now with the engine out of the truck

[nobox351y]

That looks a lot better than the 5.3 I just slid into my suburban. Keep plugging away. It will go together quickly as soon as all the parts are there and ready.

[Lost81c10]

so i have been collecting all the parts that i need for the engine. mainly gaskets and seals, timing chain set and oil pump, for the most part i think i got all that i need but a few odds and ends.

Also got my mounts.
I decided to go with Tejas Steel Works to be able to use my stock oil pan and keep my a/c in the LM7 stock location. i still need to paint them but...

on a side note; the truck will be taking its last drive tomorrow to empty out the gas tank before i start removing the engine and funny how things work, a lifter has started to make noise upon start up every morning for about week now. well that's what it sounds lie to me, it sounds like marbles hitting together on the passenger side.

[Lost81c10]

I have also been patiently working on cleaning some of the part that can be cleaned; valley pan cover, oil pan, pick-up tube, windage tray, front/rear covers and all bolts. I was pretty surprised how good they cleaned up with the cleaning solution from Summit with almost no scrubbing effort just had to let them soak for a while.

[Lost81c10]

Here is how the pan and all other covers looked like... I know they are not going to be seen nor will it give me extra HP, but i just couldn't throw them back on looking the way they were, lol.

[Lost81c10]

so along the lines of clean parts affecting performance.
I know that my engine was working ok in my suburban but in the case of my valves and intake/exhaust ports looking like they do, how is the engine affected by this. and I ask to see if the benefits of cleaning them would out weight the cost/effort at all. I tried vacuuming as much of the small debris as I could, but some still remains and that worries me. maybe it is nothing to worry about therefore, i ask.

some have mentioned that if it was running before I should be ok and I understand that. I can go with that, but i am just wanting to weight benefit vs cost, effort I don't mind at all specially now that its open. thanks again.
