As you know Craig....there is always "and then some"....[emoji23]

Did a few more items today....
Pic #1...the thermostat housing and attaching parts are now painted and ready for install when the time is right...
Pic #2...although the thermostat and the hose fitting were corroded to an extent.....the inside of the housing was extremely clean with no crud buildup....
Pic #3...Also did a preliminary cleaning in this area...will probably used compressed air and blow out the heater core....hoping not to find any major crud in there....20210502_184333.jpg20210502_184450.jpg20210502_205436.jpg

Thanks for doing this Tom. I've followed this thread and now that I need to change my AC compressor, I just checked the beginning so I could get the TB off. I've had my plenum off 4 times, but I'm hoping its easier just to take the TB off and get to the compressor.



The FSM says "remove bolts," but it doesn't say how many. 4 are easy to spot, but I'm glad I read this so I knew to remove 5!

Hello Gary....glad that this thread is helping you out.....I know that we all have our way of doing things....and I am not implying that my way is the correct way...but I hate messing with the TB....unless I have to...as when I took it off to clean and reinstall way back when....so rather than take the TB off....I rather undo the plenum and prop it up with a small block of wood in the front and IIRC....that may give you more than enough room to remove and reinstall the AC compressor....remember that my front end has been apart for almost 3 years.....lol..(I just looked at my AC removal posts) and I like removing the plenum...if propping it up doesn't give you enough room.....if you do end up removing the TB and not remove the throttle cable or the TPS etc.......you should be fine with the reinstall and not affect your settings....as you more than likely know... I have my replacement AC compressor which is ready to go....and have a vacuum pump to do a vacuum pull....once I get everything together....and IIRC our system holds 8oz of compressor oil.....I think that I listed that somewhere in the thread....found it...post #446....also I bought from a company that deals directly with Denso....and I called Denso and spoke to the tech rep there... the replacement compressors come from the factory with 4.1oz of oil as mentioned in post #446....so be sure not to over or under fill the system... and depending on the year (as yours is a 90) make sure to use the correct oil for the type freon you have in your system....again...things you already know...good luck and keep us posted on how it works out...as I will be doing the same thing once I get the car back together....lol

Good thoughts Tom
It might have been just as easy to pull the plenum, but I did get to the AC compressor by removing the TB.


Now ... my issue is the replacement Denso compresssor has a different electrical connector on it, so I need to swap, but I also need to figure out which terminal should be + and which - [mine is a '90]



I an running R134a and I'll ensure it's PAG if I need to add any.

Some FYI....which already be common knowledge to some...if you need to replace the coolant reservoir hose that attaches to the heater core...I found that the AC Delco hose is reasonable and made in the USA...purchased from Rock Auto....I still need to decide which way I will replace and attach the coolant hoses going back into the thermostat housing from the firewall...maybe using a different configuration....
Also ran compressed air through the heater core and was happy to see a very small amount of coolant go into the container with absolutely no crud or anyother type of obstructions in the core...I will need to get the remaining refrigerant out of the AC Evaporator....that way I can add the proper amount of refrigerant oil to the dryer to give me a total of 8oz of oil after the vacuum pull is completed....20210511_122025.jpg

Glad you got it installed Gary....here is the PAG 46 oil I will be using... ended up buying two containers at two different times...lol...now I'll have a backup...."and then some"..lol.....since I'll only have to add 3.9oz once I empty the evaporator for a total of 8oz.....20210511_124139.jpg

Had a chance to get the tensioner prepped and painted today....here are the end results with the last pic showing prepped and ready for paint...20210602_164319.jpg20210602_164106.jpg20210602_164043.jpg20210602_162237.jpg

The following pics are the inners of the original LT5 tensioner and the the Dayco "replacement" tensioner... which some parts are used in the original...
Pic #1...original parts on the left... replacement parts on the right...
Pic #2...may cleanup the left part and reuse...or use the newer plastic piece on the right...
Pic #3...although these two parts look identical...they have different part #'s and the collar orientation are opposite of each other...
Pic #4...original pulley on the far left...correct Dayco replacement in the middle...and the steel replacement referred to on the right as mentioned in a thread here in the Forum...
Pic #5...new spring on the left... original spring on the right...notice how the original is slightly expanded more than the replacement... I am assuming that this is due to normal wear over the years....I am also assuming that either spring will work just fine....but I will use the new spring....20210603_171554.jpg20210603_171104.jpg20210603_170807.jpg20210603_170632.jpg20210603_170507.jpg

Although I have no desire to build another one...this was a learning experience and now know a few more things....ended up doing a resand and repaint...and worth the time...now that it's done....ready for install....whenever that will be..
