P30 with 3.5 mm thickness.

The o-rings are for the trans cooler which resides within the side tank, Rog.

 

Tell me more, please.

 

Look up Dwayne's intake refresh post. You rebuild the trans lines the same way.

 

P30 ? Not sure what that means. O-rings are measured by inside diameter (I.D) and cross section (C.S.). Are you saying you used a 30mm I.D. o-ring. Here's a source for metric sizes:

This is what I came across there:

My leak is at the swage where the steel line attaches to the rubber hose.

OK, .... 29.7mm ID x 3.5mm CS.

The table in your link must be in error. The tolerances shown are too wide. They must mean 3.5mm +0.10, -0.00. Same for the I.D. .... 29.7mm +0.29,-0.00.

 

If that's where it's leaking, make sure you've got it tight. I replaced that small hose that attaches at the bottom of the cooler and it continued to leak. So I decided to try and tighten it some more. The leak stopped.

 

Randy if the adapters are leaking you try to tighten them a bit, But I would remove the leakers and add some pipe sealant then install them.
I would think given the age of the car the hose connections where the crimps are are ptobably the leak points.
With this info i would also suggest that you inspaect the lines that go to the trans , usually you will see weeping, if you do then you should replace these flexible lines as well so you dont get a cat fire

 

There is nothing to 'tighten'. It is a swaged connection.

Correct, as I've been indicating all along.

Can I cut the swage collar off and reinstall using a hose clamp as shown in the pic above?

 

What I was trying to say was that we do not use O rings when we replace the coolers into the plastic end tanks. We use the flat rubber washers that come with the plastic end tank from Behr.
No O rings were hurt in the installation of our plastic tanks and coolers.
AFAIK the original seals were rubber washers and not O rings.
Not saying that an O ring will not do the job. Did you not get washers with the plastic end tank?

Yes

 

Roger,

You should be able to look at the replacement end-tank to see if the cooler ports have been redesigned for flat gaskets.

O-rings are supposed to fit in an o-ring grove to prevent crushing, while flat gaskets are compressed between flat surfaces. From the photo, the cooler appears to have a flat surface, so the 0-ring groove should be on the old end-tank.

 

Dammit Randy why be so indvidualistic? Sheesh just tightn the bloody thing like we said ... lol I took mine to a local hose place and for 40 bux they re-did them with much better hose and brazed (braiised sp?) instead of the suaging ... suaging is for p4ssies

 

OEM is an o-ring, therefore replacement with a new o-ring is correct - not a rubber washer.

There is a groove on the cooler that the o-ring sits within - look closely at that picture.

You say tomahto, I say tomaytoh.
