So taking a suggestion from Jerry to use a 6 point socket or box wrench to remove the oil hose connectors.... I ordered 2 sockets from Amazon....assuming they were metric....I ordered a 28mm and and
29mm 6 point sockets....finally got them this AM....(first set got lost).... Now this may be common knowledge too many.......the 28mm is too small and the 29mm fits....but not 100% snug fit.....tried the 29mm and just didn't feel right....sprayed down the connectors with PB Blast and then used a 1 1/8" 12 point socket and a 12 point 1 1/8" box wrench (I don't have 6 points in that size)....they both fit perfect and 100% snug....no movement.... So with my trusty hammer....broke both loose and removed... Again....may be common knowledge...but for those attempting this for the first time....hope this helps... The following pics show the tools used and I tried to take close ups of how the connector fits in both sockets... First pic....what I used... Second pic....the 29mm 6 pt socket... Third pic....the 11/8" 12 pt socket....Attachment 10368Attachment 10369Attachment 10370 Sent from my SM-G965U using ZR-1 Net Registry mobile app |
Re: TB removal and then some!!!
A word to the wise regarding installation of the new fittings; If you use teflon tape, that's OK, BUT teflon significantly reduces the friction of the interference fit of tapered pipe threads. Do not overtighten as it WILL crack the Oil Filter Housing. I have used it for decades and will continue, but you have to know when to quit tightening, especially when screwing large fittings into aluminum castings.
Loctite 565, recommended, is a paste sealant that works well. It is much like a good plumbers thread dope which can also be used. Not quite as slippery as teflon so maybe a bit safer to work with. |

More progress today....radiator drained....coolant crossover pipe removed....accumulator and main AC hose set also removed. ..
Stand corrected somewhat on the coolant hose replacements that I have....did a trial fit and they will fit over the pipes....but still appear to be a tad shorter....may just go to the store and see if they can match 2 90* hoses and then I'll cut them to fit.... Also may be common knowledge....but we all know what it's like to remove hoses from the pipes....I spread the hose a little to shoot some PB Blaster inside and work it around.....hose slides off without cutting....

Amount of Pag oil from my accumulator.....so looks like the evaporator may also be somewhat dry...since the new compressor has 4.1 oz from the factory...and our system requires 8 oz give or take a
.10 .....looks like I'll be adding about 3.8 oz to the new accumulator during the rebuild...which will give me 7.9 oz in the system....[emoji16]Attachment 10381 Sent from my SM-G965U using ZR-1 Net Registry mobile app |

Call around to a few hydraulic hose companies today and even went to see one....apparently no one does automotive lines....as they don't have the ability to crimp the hoses to the tubing....I have one other company to check out....otherwise I will just reuse what I have....my concern was with this one crimp that was worn down from resting again the pipe...blew compressed air through....although not pressurized....and no leaks that can be determined....they are Goodyear USA made hoses and even with the one spot that is worn....still look to be in decent shape...just did a slight cleanup....and will do a respray...and they should do the job...Attachment 10382Attachment 10383

Not trying to spend your money, but.... Now’s the time to install an all aluminum radiator. Do you really trust the 25 year old plastic tanks on the original??? Even if it passes a leak test? |

Fans went from looking like this in pic #1 to like this in pic #2....pic #3 shows one of the radiator rubber supports...it appears that this system was removed before....as the front of both rubber supports where the condenser sits....was reformed during installation...as the time wasn't taken to make sure the parts sat correctly in the support....pic #4 shows a first cleaning of the supports...plus you can see how the rubber was deformed...tried in pic #5 to reform the support....but then thought it might work out better as shown in pic #5...#6...& #7.....just taped to the condenser itself....we shall see...will probably go with the poly version...sine the OEM rubber versions are not available...
Also getting the AC Compressor manifold hose assembly repaired...should be completed in a few days...interesting on how they are doing the repair....[emoji16][emoji16]Attachment 10428Attachment 10429Attachment 10432Attachment 10433Attachment 10434Attachment 10435 Sent from my SM-G965U using ZR-1 Net Registry mobile app |

Just picked up my AC manifold hose assembly from being repaired @Kenco Hydraulics in Hatfied PA.
Did a search in my area and they were the only ones to take on the repair. They did an excellent job and made some improvements at the same time. You will notice that the accumulator rubber hose is now shorter and there is a slight bend in the metal tube...where there wasn't before. Also JIC fittings are now implemented into the assembly....making it much easier to clock the connections during reassembly on the car. Even though the accumulator rubber hose is shorter....measurements were taken beforehand to make sure that the actual length of that part of the assembly were indeed correct. I think the main concern when reattaching on the car is to make sure that the hose does not rest against the crossover coolant pipe as it did on my engine....causing the wear problem that resulted in repairs. Again extremely happy with the work that they did. They are also open to doing the same for anyone who needs this type of repair....just let me know and I will give you the info... As you can see the repaired assembly in the first 3 pics with the replacement hose and the JIC connections....the next 3 pics show the old hose that was cut off and what the end looked like from resting against the coolant crossover pipe for 25 years....Attachment 10480Attachment 10481Attachment 10482Attachment 10483Attachment 10484Attachment 10485 Sent from my SM-G965U using ZR-1 Net Registry mobile app |
Re: TB removal and then some!!!

What are JIC connections? |
Re: TB removal and then some!!!
JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved.

All I know it is going to make it a breeze for install....it was recommended to hook up the compressor then the accumulator then tighten the JIC connection closest to the accumulator and then tighten the JIC connection closest to the compressor....no sealant of any type is required or recommended....:) |

Figured I run by Ace Hardware to look for 2 bolts for the cooling fan to attach to the fan shroud....I was missing one and those small 7mm head bolts used for the upper and lower radiator shroud attacement....Ace was a bust...went over to Lowes which has a better Hillman Automotive selection than HD....IMO and found exactly what needed...
Also received my shipment of rosebud clips for the fan conduit harness connection to the fan shroud....success...[emoji16] Pic #1 is the bolt used for attaching the fans to the fan shroud....10mm head bolt as shown in pic #2...replacement bolt is on left side in both pics...although slightly shorter @25mm length instead of a 30mm length (stock size)...should work just fine... Pics #3 & 4 show the small 7mm head bold (which both a 7mm and 9/32 socket will fit) that is used for the radiator shrouds and also attaching the oil cooler to the condenser....replacement bolt is also on the left in both pics....should be a 15mm length (stock size)...but this is a 20mm length...which should also work just fine...

Pic #1....these are to my knowledge the original LS & RS Upper radiator supports... Pic #2...another view... Pic #3...support on the left is from the 94....support on the right is a purchased part....the configuration is opposite....

Pic #6...another view... exactly the same.... Pic #7...now here is the bottom support...unit on the left is from the 94....unit on the right was purchased... the orientation although on the same side...is also off to where this may not properly fit... Pic #8...you can also notice the difference in the orientation from the bottom side....only thing I can think of..... is that...this is from an earlier C4 and being sold as a 90-96 part....Attachment 10551Attachment 10552Attachment 10553Attachment 10554 Sent from my SM-G965U using ZR-1 Net Registry mobile app |
