Description of a design, removal and installation of lines and hoses of cooling of transmission

Description

Hoses and lines of cooling of transmission are joined by means of sockets of a bystry joint. Flanges of cooling lines are used as sealing surfaces. Together with flanges collars of wire type are applied to fastening of lines on the union. The collar is established behind a flange and serves for fixing of the line.

The typical nipple connections used for joining of the cooling line with transmission (at the top of) and for a line joint with a hose (below).

Depending on a year of release of model, in cooling lines three types of nipple connections (sockets) can be applied:

a. On sockets of the First type access to a fixing clip (collar) is open.

First type of the nipple socket of bystry joining (all models 1993 and part of models of 1994 of the issue).

b. On sockets of the Second type the clip and the case of the union are wrapped up by the taking seat material.

Second type of the nipple socket of bystry joining (some of models 1994 and models of 1995 of the issue).

c. On sockets of the Third type the clip is closed outside of the metal coupling tense on the union case.

Third type of the nipple socket of bystry joining (some of models of 1994 of the issue).

d. The nipple connections of new type used on models of 1995 of the issue. Are equipped with the built-in lock uvulas.

Undocking of the majority of types of nipple connections of a bystry joint requires the special tool:

  • On models of 1993 of the issue undocking of sockets of the First type requires the tool No. 7555 or its equivalent.
  • On models of 1994 of the issue the tool for undocking of sockets of the Second and third types is put on directly tubes of lines. The tool provides expansion of a clip that allows to disconnect the line from the union. The same tool can be used also for undocking of sockets of the First type which are still used on models of 1994 of the issue.
  • Sockets of the Second type are used as well on early models of 1995 of the issue. Their partition is made just as is described in point b).

The sockets of new type used on models since 1995 by the issue do not demand application for the undocking of any special tool. They are equipped with the built-in lock uvulas.

Sockets of new type (model since 1995 of the issue).

Tubes, hoses and nipple connections of lines of cooling of transmission are not subject to repair. The damaged components have to be replaced (assembled).

Removal and installation

If unions, hoses or tubes of cooling lines are covered with dirt, lubricant or dust, clear before undocking about use of degreaser. The plastic tool for undocking of components will not enter the socket if the last is filled with foreign particles.

All sockets, except for sockets of new type

 PERFORMANCE ORDER

  1. Enter the plastic tool for undocking of nipple connection in the socket against the stop into a line flange, then press the tool, at the same time turning it for an otpuskaniye of a fixing clip (collar) and, having pulled, remove the line from the union.
  1. Enter the plastic tool for undocking of nipple connection in the socket against the stop it into a line flange, then press the tool and turn it, releasing a fixing clip, and, having pulled for the line, remove it from the union (the socket of the Second type is shown).

Sockets of new type (only for models since 1995 of the issue)

 PERFORMANCE ORDER

  1. For undocking of sockets of new type just fingers squeeze together lock uvulas. Pay attention that the union insert after a partition of the socket remains on the line.
  1. For undocking of sockets of new type just fingers squeeze together lock uvulas (pay attention that after a socket partition the insert of the union remains on the line).
  1. If the insert of the union is not damaged to remove it from the line optional. In case of need replacements of an insert just move apart lock uvulas of the socket and remove an insert from the line.
  1. If the insert of the union of the socket of new type is damaged, remove it from the cooling line, having parted for this purpose lock uvulas of the socket and replace new.

All sockets

 PERFORMANCE ORDER

  1. Zakuporte the open ends of cooling lines in order to avoid hit in dirt transmission.
  2. Examine unions. If the union or a fixing clip of the line are damaged, all socket has to is replaced with uniform assembly (in replacement of the metal line if it as need is not present). Before installation of the new union do not forget to grease its carving part with Mopar Lock N sealant’ Seal, Locktite 242 or their equivalent. If the fixing clip (collar) jammed on a hose is damaged, the hose and a clip have to be replaced assembled.
  3. Wipe the union and the hose/line with pure dry rags.
  4. Insert the line into the socket and press it before click of a clip.
  5. For check of reliability of joining try to disconnect a hose (line), having pulled for it.

In all sockets the clips of wire type serving for fastening of the cooling line in the socket are applied. If the clip is bent or in any other manner deformed, normal pressure in the line is capable to force out the line, having caused leak of liquid and, as a result, failure of transmission. SURELY in the most thorough way check reliability of fastening of cooling lines of transmission in the docking sockets.

  1. Fill in in transmission liquid of the required grade (The head Nastroyki and routine maintenance).
  2. Make trial runs of the car and check on existence of signs of leakages of cooling lines of transmission.
