Glock's new project: "Fred" w/ 5.3L LS swap info

[glock35ipsc]

Yesterday, all at the same time, northern Colorado was under a severe thunderstorm warning, a winter storm warning, and a tornado warning. And at the time they all came out, it was blue sky and sunshine here at work. But before the day was over, all three events happened at one place or another around the state!

[nlped]

Sweet!

Okay, now when does the trailing arm mod start

[glock35ipsc]

When time allows! But at least it's getting warmer..... oh, wait. That's right. Rain check on that. Oh, wait, it's still raining. Ugh!

Now that I have A/C I might be tempted to drive him more often this summer, so that might be the winter project.

[nlped]

I understand.

[Jhogan830]

Go fred go! =p

Bob I need your help again. Now that you've done the ac. What size is the fitting from the evaporator to compressor ? And also the one. From condensor to compressor ? That and to figure out how/where to hook a fan to is all I need to get mine going and not BBQ my self with this 100+ temps in the summer here lol

OK, so there are three different lines:

#1 evaporator to the condenser
#2 accumulator to the compressor
#3 condenser to the compressor

So,

#1 - This is an aluminum line that you can reuse from the old setup. If you don't have one, or if the one you have is damaged, you will find a part number for it in the link below and where to order one. These are #6 fittings, so they will need new #6 o-rings.

#2 - The accumulator end is a #12 90* fitting (for a #10 hose). The compressor end is a #10 45* fitting. Use a #10 hose.

#3 - The condenser end is a #8 90* fitting. The compressor end is also a #8 90* fitting. Use a 8# hose.

Here is a complete parts list from getting mine setup and running:

Fan - are you going to run electric fans, or a mechanical fan? Did Jesse/W4M do you harness? I don't remember.

Regardless, if you are going electric, there should be wires coming off near the PCM for electric fans if that's the route you are going. I believe the wires for an electric fan are ground signals, so you would need to run 12v battery power to a relay, and use the ground wire to trigger it.

Here is what the fan connector looks like. I left the fan wiring in mine in case I decided to run electric ans later on. But since I've decided to stay with the mechanical I'll probably cut them out. There are two wires: one for low fan speed, and one for high fan speed. Since my engine came with the electric fans, I am just guessing that "low" is one fan one, and "high" is both fans on.

And speaking of Fred's 4x4'ing adventure yesterday, it looks like I have some cleaning to do!

[fpjr0]

thanks Bob those fitting size's will help.... as far as the fan deal goes,,,, I re worked my own harness, and I have both "low and high" fans so the pcm controls the fans according to the temp of the coolant..... but I was thinking that the low fan comes on and off when the a/c is on regardless of the temp of the coolant,,, so I was thinking of adding another relay but, I dont know where to get the trigger signal from in the a/c system..\


also.. looks like Fred is in need of some Major help right now....

[glock35ipsc]

I don't have my A/C wired through the PCM at all, so I don't know how to set that up. But if you just need a signal to tell the relay when to come one, just tee a wire off of the gre compressor wire.

Fred is a little happier after about an hour with the pressure washer. But I'm going to have to pull the plastic shields off of the gas tanks, there is mud PACKED between them and the tanks. I think I'll pull the bed too, that crap is packed everywhere.

[Driveway Dreams]

Fred...you only spin 1 tire, sometimes 2. THINK ABOUT IT!

Well at least he will be clean. That storm was a good one. And the wind, wow!

[79gmc5.3]

Hey Bob, you need to make Fred a 4 X 4!

[glock35ipsc]

Nah, but he could use a taller sibling!

[Driveway Dreams]

Doesn't he already have a taller, older sibling? Goldie.
Maybe they both need a taller, much younger sibling.

[Butcherboy]

Be easy on Freddy Bob! LOL! That chassis is a MUD magnet!

On my 87' I drilled 6-8 2" holes for drainage. Lost a Tank to rusting out cause the trapped mud!

Question. Did you ever get the temp sender for the dash working?

I going with Auto Metter gauges, and found 12mm Adapter and Sending Unit to work with the rear passenger water hole. I just ordered the parts today,



Little Red is almost there!

Auto Meter part no. 2277 Metric 12mm Adapter http://autometer.com/cat_accessoriesdetail.aspx?vid=61

Auto Meter part no. 2259 Correct Metric Sender Unit.http://autometer.com/cat_accessoriesdetail.aspx?vid=33

[glock35ipsc]

I think I will pull the bed off this weekend just to get everything else cleaned up. I need to anyhow just to put the vents on the gas tanks.

That is the same hole I used for the temp sender. The original adapter I bought from S&P was a POS, so a fellow board member made me a couple that are the bomb:



With the POS adapter from S&P:



They work great! I had a small leak from the beginning, it seeped between the adapter and the sending unit, and it would drip onto the manifold. Not really a big problem, but man oh man burnt antifreeze stinks bad! So when I was finishing up the A/C I pulled the adapter out and used pipe dope between the sending unit and adapter, and between the adapter and the head. No leaks now!

[Butcherboy]

That's Nice! Better for your swap, since your using stock gauges! Yeah the sh*t stinks! I have weak lungs, and never been as sick from anything like burnt anti-freeze!

Bob now that you told me where to connect the vaccum source for the a/c modulators, where is the line to the modulators at the engine bay?

got the sanden compressor installed with the kwikperf. brackets on... went to the vintage air which is local for me here in san antonio, and they didnt have the oem fittings I needed, but when there I met a guy that has a a/c shop and made me two a/c lines with fittings for 50.00 so I guess it wasnt so bad.... just need to hook up the vaccum so I can adjust where the air comes out in the cab,,, cold air in the feet is not the best place to have air coming out , around here in south tx anyways... hot hot hot...

[glock35ipsc]

That's a good price, you did good.

The first pic shows where the line runs into the cab. It's to the right of the box (looking at the firewall) that the evaporator is in. It is a solid plastic line, not a rubber vacuum line (on mine anyhow).

The second pic just shows the three different vacuum lines: yellow is from the "tee" and runs to the inside of the cab, light blue is from the vacuum port on the intake manifold, and green is to the vacuum canister on the drivers side.

[fpjr0]

and once again, Bob comes thru.... I should get a price for Highjacking and soon the most questions on this thread..lol I know I keep saying I am gonna start my own, but I know how you guys like pics and since I dont take many, it would be a very boring thread lol,,,,,,,,,,,,, thanksss... that vacuum canister is for the cruise isn't?


by the way.. it good to have a/c now,,, and it s*ck , that just mowed the yard at 90 degrees weather, and peeps are talking about how "nice" the days have been...

[fpjr0]

I think I have Bobs next project and Fred sibling as you guys were saying....

:

[glock35ipsc]

Hummer, yuk! LOL, I like that bolt-on tracks though. There are a couple rigs where we snowmobile that use those - an older Wagoneer and a Burb. I prefer our Thiokol at the sheriffs dept.

Did I mention how nice it is to have A/C again???

[79gmc5.3]

Did I mention how nice it is to have A/C again???

[/QUOTE]

OK now your just braggin. Us poor suckers living in the south with no A/C yet

[glock35ipsc]

Sorry man!!

On another note, for some reason I've been imagining what Fred would look like wearing a pair of round eyeballs.......

[fpjr0]

I meant the tracks not the actual hummer,,,,
