Title: Tranny cooler lines
Post by: R. Dave Carr on May 24, 2008, 03:50:34 PM
Well, I've somehow developed a leak in one of the tranny cooler lines that run to the radiator.  Didn't leak before I pulled the radiator, but it sure does now.  Any one have any spares, or reccomendations as to what else I can replace the line or lines with?  I have a cruise in 3 weeks, would be nice if the car could go..........(http://www.moparfins.com/forum/smileys/smiley22.gif)

You can use compression fittings and make a new piece.
 
Where is it leaking?
Title: Tranny cooler lines
Post by: R. Dave Carr on May 24, 2008, 07:44:33 PM
Looks like just behind the crossmember.  One of the lines appears to have been spliced twice already.

Youcan get new lines from any company like Fine lines...But it's not easy to install hard lines when the motor is in the hole....I had to do this on the wagon and it SUCKED!!!!(http://www.moparfins.com/forum/smileys/smiley5.gif)

Well maybe third times the charm for a repair...(http://www.moparfins.com/forum/smileys/smiley17.gif)

Some copper tubing, a proper flare-tool and perhaps a tubing bender for nicer bends will get you a long way.

Put in new lines a few weeks ago.
If I can do it, you can do it (But don't use copper.  Too soft!)
Title: Tranny cooler lines
Post by: Steve on May 25, 2008, 05:47:07 AM
Yes   Copper is too soft and will deteriorate in time from metal fatigue.  Use the steel
 
Then I suggest you cut out the piece that has been repaird several times and install a new piece with the compression fittings.
 
I am assuming you don't have a double flair tool, otherwise I woud say make a new one.  Two pieces of 5/16. a coupler and a bending tool with the flair tool is all you need.  And allot of patience.

Herm  Is that a 62?  I can tell from the trans mount is has to be a 62, 63, 64.  Well a US version.

'64. (http://www.moparfins.com/forum/smileys/smiley2.gif)

Of course as with all copper-lines, make well sure it's mounted vibration-free to prevent metal-fatigue.

The only place we ( in the resto shop) use copper line is from the radiator neck as a drain tube, oil pressure lines to gauges, and as vacuum lines to wiper motors. Steel or stainless steel is used for everything else. It's just the way I have been taught over the years....I know racers use aluminum for the main fuel lines, but I want the sturdiness and safety of double flared steel in my car.

Title: Tranny cooler lines
Post by: Snotty on May 26, 2008, 10:12:59 AM
I'll be the contrarion here.  You can use a good, heavy fuel line instead of the metal ones.  They're easier to install, won't crimp if you bend them the wrong direction, and are far cheaper.
 
People poo-poo this idea saying they will leak and are not factory original.  I used fuel line on my van with no leaks for 100,000 miles.  One of my two lines on the Newport are such, with no leaks, and I installed it in 2004.

There's nothing wrong with decent copper lines. They are also used for the pressurized propane on cars over here, and the pressure is 10-30 times higher than the transmission fluid pressure. Safe and durable.

I agree with the Snotster here, I fixed Mobby's trans line by using
fuel line and its hasent leaked since. It was far more cheaper and
hasent given us a problem since I it on.

Well, tranny lines are run.  Hands are quite raw after shoving that tranny cooler hose onto the push-lok fittings.  No leaks that I can see either.  So, what do you reccomend for cleaning "Lake Dexron" off my garage floor?
Title: Tranny cooler lines
Post by: Steve on May 28, 2008, 09:39:39 AM
Kitty litter (Unused is best)  then some Gunk engine cleaner and a hose.  Spray it down good with the cleaner and wash it good.  Then hit it with some Dawn dish detergent and a broom.  Wash again.  Stain all gone!
 
I hope those push locks aren't plastic and the seals are oil impervious.  I would still suggest compression fittings.  More reliable.  But I'm old fashoned.

Make sure your hose clamps are nice and tight and there should be no porblem.
 
Sorry I didn't get those pictures to you.  (http://www.moparfins.com/forum/smileys/smiley11.gif)
 
Every time I work on a transmission my arms look like they are bleeding!  That stuff is a mess!
Title: Tranny cooler lines
Post by: R. Dave Carr on May 28, 2008, 10:14:51 AM
Parts store didn't think those type needed clamping, but I can do that when I get the car on a lift here shortly.  Gotta watch how closely they are to the engine fan.  Found out the easy way when I installed the new to me clutch fan last night.  Truned the fan by hand, and felt some rubbing.......(http://www.moparfins.com/forum/smileys/smiley17.gif)

5/16x1"  The rubbing was the fan blades on the new trans cooler line.

I went all rubber with those fittings screwed into the radiator and trans.  Hoses are pushed on tightly past the second barb.  I have the raw hands to prove it today.

Rubber or not, they should not be any closer to the fan than the originals were.  They should be below the arc of the blades.  Are you using the correct fan?  Or, did you route the hoses kin a different place from the originals.?  You should have routed them through the same place the originals were in.
 
I just went and looked at mine.   They are well below the fan shroud and routed next to the oil filter.  The fan should be no where near.

My passenger side hose is right next to the tank as it runs across.  That was the one rubbing.

Doesn't you car have a fan shroud?  It should run below the shroud.
 
In any case, remember what I said about using nylon ties.  Can you route the passenger side one under the shroud, and hold it there with ties?  Then, run the rest of its length parallel with the driver's side.  It's OK if one hose is longer than the other.  Once they fill with fluid the pressure will be the same on each side.

First of all I disagree with running all rubber.  Long term it will be a problem.
 
No matter how far you have it from the exhaust the heat will deteriate the rubber quickly.  I strongly urge you go back to steel.  You can splice it together witht he rubber in the front, but the back is where all the heat is.
 
I know I know.  I'm just telling you from experience.
Title: Tranny cooler lines
Post by: R. Dave Carr on May 29, 2008, 10:05:55 AM
Well, the steel lines that came from under there are dead.  All I can do now is live with the rubber until I can et a set of steel lones in, and then fight to get them installed.  As long as the rubber gets me through a month or two I should be fine.
Title: Tranny cooler lines
Post by: Steve on May 29, 2008, 10:11:02 AM
A month or 2 will be OK.  I am concerned about the rubber.  Suckers could leave you stranded.
 
If you need the tools to do the job, I can loan them to you.  Benders and flairing tools.  Just pay the shipping back and forth.  When you are ready shoot up a flare.  You can use your originals as a template.  They really aren't that hard.
 
I have several of each BTW

I truly appreciate the offer Steve.  I figure what I will probably order a set of the reproduction lines for 50 bucks and install those.

It took long enough for someone to say this, and I'm sad it was tou, Steve.   But, Horse-puckey!  A month or 2???  Did you read what I wrote earlier?  I had rubber on my van for 100,000 miles, and I drove it to every state in this country - in the summers!  I have it on my Newport.  When I put it on Mike at Olidale Auto Parts said it would leak in six months - that was in 2003!
 
Come on; say you don't like it (as you did), say you wouldn't use it, say you'd rather drive a Ford, but don't toss out a supposition that has no merit.
 
Do your non-pressure power steering lines go out in two months?  What about your fuel line?  Heck, it's right next to the motor and full of fuel to boot!
 
Or, perhaps my expierience is just not as valid as yours.
 
Sorry my Friend, but that comment was too much.

I just installed replacement transmission cooler lines that I bought from Inline Tube.  It wasn't that difficult to route the pressure line since my car is up on a lift.  I am not pleased with the fit, since it isn't an exact replacement, but the bends were close enough that I was able to get it hooked to the transmission after doing some pushing and bending.  I have yet to get it connected to the radiator, since it is about an inch too short.  I will need to straighten some of the curve out of the front of the line to make up this 1".  I compared it to the one that I removed, and at the front end, it was exact.  At the back end, it was almost totally different.  I didn't see the "shortage" issue until I had the line installed and at that point, I wasn't taking it out.  I will send them my original for a pattern if they will send me back a replacement.  Inline Tube uses a steel line that has a copper coating on the inside.  www.inlinetube.com
I see no problem with using rubber for lines, except for the issue of the rubber tube possibly rubbing and getting a  hole in it.

Are you sure they weren't for a B Body and they say they will fit in a C?  Actually the configuration along the engine and trans would be the same.  If it were for a B Body, it would be short.  Maybe you can pull out what you need from the bends.  Did the fittings line up at the rad?  They should have. . . .
Title: Tranny cooler lines
Post by: Paul on June 10, 2008, 06:59:38 AM
Inline Tube said that they were for a 1963 Chrysler C body, just as I had ordered.  There information indicated that it was two lines without an inline filter.  I said that I need the 3 line kit since mine has the inline filter, so I have to assume that they sent one that was for a 1960 - 1962, since that is what they list for 3 line kits.  They claim that Chrysler used more than one supplier for this part, and that the supplier might have made it differently.  I know that  this isn't correct, since all suppliers work with the same engineering drawings, and have to produce the item to that standard.  The auto manufacturers don't allow suppliers to deviate from the drawings.   I haven't gotten to putting the fittings on the radiator end, but it appears that they will line up.  I work very slowly when it is hot, so this is a drawn out project.  (http://www.moparfins.com/forum/smileys/smiley4.gif)

Post by: Steve on June 10, 2008, 09:04:37 AM
They all had inline filters up to 1965 as I recall.  But you can't get the filters anymore.  You CAN install a 727 filter in the trans pan though.
 
You are right.  Someone handed you some BS.  You probably could have used a 2 line kit for a 65 and accomplish the same thing is you eliminated the filter. . . .

   If you wanted, you could use this filter for the tranny fluid. 5/16" lines and all...

   That filter is designed for tranny and hydraulic fluid. It is actually listed as direct fit for early 80's honda's. (Oops!, bad word)

I ran a trail repair very similarly...was not for 100K but it was for ~20K and it showed no signs of any deterioration.  *shrugs*  Later I spent the time and put steel ones in.
