well, first thing i noticed when i got on my creeper and rolled under the Sierra is that there is alot less ground clearance than my 87 K20. I couldnt roll from the nose to the tail like i can with the older truck. What a difference 16 years is between trucks..

I was looking for a location to put a tranny cooler (4.8L) and didnt see any obvious spots. There is a skid plate (more like a plastic cover for all the steering components) that i thought about tucking up in there. Best bed is to try and get one up in front of the rad.

Saw the transfer case and its special note to techs calling out that it is made of magnesium. cool.

How do i know if the torsion bars have been adjusted? the truck rides good and is flat (nose isnt down more than the front).

The fuel pump is mounted on the frame and not in the tank, thats nice.

Looks pretty solid under there. Alot cleaner for sure than my old one..lol

I didnt see the oil filter, but didnt look too hard for it.

Plugs look easy enough to change out. Only 54K miles on it so i ll wait a bit longer. Saw that the gap is .060". pretty high isnt it?

just some thoughts on things i noticed while crawling under there.

The tranny is a 4spd. Is this still the 4L60E?

any other things i should know about that anyone can think of?

thanks.

later all.

Tranny cooler is best in front of radiator and mount it on drivers side if it is open as it will have least impact of engine cooling there. Make sure you route oil through radiator cooler first then aux cooler. Yes they are lower and the cross member under tranny/xfer case does not help matter either. At least in the classics (88 till 99) that cross member was inside of frame rails.

Hayden will work too. To me brand does not mattter as much as the size for application and its presence. Something in the neighborhood of 6 to 7 inches wide by 12" or so long will do nicely. Advanced Auto sells a brand that I have used for over 25 years and with good results too. (never lost a tranny with one)

Stacked plate coolers work a little better than tube/fin coolers. Less pressure drop, more surface area, etc...

Thanks for taking us there, Lee. Ever thought of being a poet?

 

Well done!

 

Yeah, that's the venerable 4L60E.

They also restrict airflow through the core and rest of cooling system a lot more too and the airflow needs to get to rest of system too. I prefer the tube and fin for this reason and using a infered temp sensor I get a 25 to 30 degree drop across my fin cooler at a idle with engine is warm and clutch fan is engaged and my cooler is about 6 x 13 and a tube and fine type. This is after it passes through tank cooler too.

I got my trans cooler from Summit, it's a PermaCool 17,000 GVW. I'm very happy with it...just had to paint it flat black prior to installation (it came bare aluminum)

      Auto start stop disable

      By dennismc · Posted

      I installed the Auto stop eliminator on my 21 Sierra SLT shortly after I got it. They have a detailed video instruction on how, took me about 20-30 minutes to do. I was apprehensive too to start tearing apart a new truck but it was pretty easy install. Like you mentioned get some trim tools. I went to Harbor freight and picked up a set. If you can find some install videos/instructions to give you and idea for a plan of attack you should be fine.

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      OCI, not when but why?

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.

      WOW, something we agreed on. I only bought at sticker twice. A 94 impala ss and an Acura intagra type r. Made money on the first. Still have the second.
