What Did You Do with Your 80 This Weekend?

[nigelsiam]

Spent last night camping in La Sal. Campsite was over 8000ft.

All the cooling system components on the truck are less than 2 years old but i was still seeing high temps. Might be time for a flush and some fresh coolant.

Today we took a spin round Imogen Pass. I always thought it was just a high altitude dirt road that a regular stock Subaru could manage so was quite surprised what i came across. Fantastic day.

At the summit I parked up for a bit and could hear the gas in the tank boiling. I loosened the cap and let it vent. It took over 10 minutes for the pressure to equalize. I was surprised by this as i have the modded charcoal gas canister so i guess i need to look at that also when i get home.

I've had that boiling gas situation before too and it's no bueno! You said your coolant temps are high? What temp do you consider high?

Those aren’t Yokohamas

Good catch. He swapped them back out and I didn't look closely.

Ordered a Derale dual pass cooler for the front. The black one was out of stock so I went with the raw finish. It is nice it comes with the correct barbs/fittings for the hoses. Now I just need for Summit to figure out if they have the correct Lares 11580 steering box in stock. Once I get that I can start the steering box/pump/reservoir/hose refresh.

To go along with the new hoses I am going to be wrapping them in a heat resistant covering. We all know that those hoses can get rock hard and deteriorate over time and along with under hood temps I want these hoses to last a long time.

We camped in Gunnison National Forest on Saturday and the run from Montrose to Sapinero has some pretty long climbs. I first noticed the AC cutting out which is a tell tail sign that all is not well. I connected the Torque App for the rest of the journey. Highest temp i saw was 230f.
I grew up driving manuals in mountainous terrain so i know my way around the LC transmission and how to use it as a semi automatic.
That road is at 8000ft so with the air around 25-30% thinner cooling will be impacted however that same stat also means the truck is 25-30% down on power which should mean it will not generate the same heat.
I have never been aware of heat issues on my truck before so need to give this some serious research.
The first thing that springs to mind is that i run 315's but have never regeared the diffs. The first step might be regearing so the speed/rpm ratio is back to factory specs.

More cleaning, prep (lots of tape), a little more rust converter from that leaky master cylinder, and bit of paint. More painting to come.

Do you have a modified blue fan clutch (oil viscosity and timing mod))?

 

[Irish Reiver]

Do you have a modified blue fan clutch (oil viscosity and timing mod))?

Yep, new blue clutch fan with 15k oil. Clutch, radiator, hoses etc. are all OEM and about 2 years old.

Where are you jacking from, just about any jack should work if you put it under the axle.
Even the OEM jack.
A 35” puts the axle only about 1.5” higher off the ground.
High lift jacks have there place but there very dangerous and only work on rigs with full armor.

I have used the OEM jack with a small block to remove my 39” tires
Does you rig still have the OEM jack ? I still carry mine.

In the shop a floor jack works perfectly under the axle.

I built this carriage for a hi lift and it mates to a notch in the bumper that I built. It’s my pet rock. Makes a hi lift much safer and a roller clevis(not in the pic) pins it in. Then a pin through that and you’ve pretty much got a jack stand. Filed a patent and it’s time for another one now. You can also lift from the top of the bumper if needed and it all needs more R&D but it’s been working well for me.

I have seen temps creep before a fan clutch upgrade but not after. Maybe check that, did you do the fluid swap or buy it already done?

Cheers

Only getting one day to work on the 80 has been a bummer.

16 quarts of fluid swapped out, new trans pan with temperature bung welded on put on the truck with sending unit for the manual gauge, Dakota digital fan controller and spal fan mounted up.

Sometimes rock auto is awesome but they really sucked this time sent me a filter for a 95-97 transmission wouldnt work with the 93. Oh well, some brake clean seemed to clean the mesh filter good enough. Hoping to keep my trans around 190 degrees from now on.

Ah....yeah that is too high!!! Hope you figure it out.

Ya 93-94 don’t have a filter just that screen that need to be cleaned

 

[76lcmike]

Got this pig back in, gotta a lot of work to do, waiting on harness clips and another $1500 in parts from the july 4th sales. Normally I have the intake all buttoned up but since this is a RHD it’s so open on the left side.

honed the cylinders, and working on getting the oil pump driven gear bushing out.

I'm trying to be positive about this. You're not helping much...

I actually keep a pair of mouse traps in my rig to handle those subversive vermin. The deceased shown in this photo was responsible for putting the munch on a bunch of my camping groceries including my Smore stuffs.

Word of caution and nothing against either Summit or Lares. Customer service by both Summit and Lares was above and beyond.

There is some misinformation on the steering box from Lares, they apparently taper the output shaft and per the email I received from Summit today and I quote "The output shaft is measured at the case where the shaft comes out of the case, 35.38mm is what I get on ours. According to vendor that is correct."

From the pictures I have seen on Cruiser Teq the heavy duty sector shaft does not look tapered. Please correct me if I am wrong.

So it looks like I am going to keep this box possibly and just re-using my original pitman arm, barring a deal.

A tapered sector shaft just seem weird/ wrong

I installed a transmission aux fan kit. The fan kicks in when the oil temp reaches 185 and turns off when temp gets down below 165. But I have never seen my tranny temp above 165.

AC cuts out at 226* that tells me Mr T felt that that temperature is fine.
I still don’t like it !
I don’t that you tire size is the issue
I would start with the fan clutch.
If nothing has been done the cooling system is in need of a refresh

Yes it does, Lares said they do it to ease installation of the pitman arm.
