Heater hose ?

Well changed the core today, got it down to 3:45 minutes start to finish. Hopefully wont need to do another one for awhile as now all here are done. The hose that runs from the metal tube to the core needed replaced so I got one but my question is this. In the old hose was a small insert that I have pictured. What is it and what is its purpose. I didnt put it back in as I see no value to it but let me know if I should.

jcassity: from what you asked me before to check I did. I checked out the case with the glovebox out and if someone was able to change a core by making a opening in the side of the case then sliding it out I would love to see it done. I would say that myth is busted. There just isnt enough room to get it out if you did happen to hack the case apart in somewhat the right area.

PUT THE INSERT BACK IN THE FEED LINE TO THE HEATER CORE!!!!!

It reduces pressure of the fluid entering the core.  Without that, you're simply cutting the cores life expectancy.  I've seen enough fox body cores blow in no time when guys don't run those restrictors to know that I would never run without one.

It's a restrictor, and yes it should be in there. If it was at the core end of the hose, it should be relocated to the end nearest to the engine.

Wasn't the move a TSB for gurgling noises?

ok I will reinstall it, when I changed the core in my kids 83 I changed hoses also and it didnt have one, I see the restrictor part# is E7 for 87 but should I try and round one up for his car also?

Also I see in the diagram that it is clamped in place, this one was just stuffed about 2" in the hose, which is best?

I stuck mine back in the factory spot after the heater core replacement. No gurgling noises and it seems to be ok.

Calm down man, my reply was only meant as informative not meant to be argumentative. You asked me to check when I did the job and report and I did. If Crystal did that fine, I dont see it as being possible due to a severe lack of space for a normal size person. I have gotten plenty of usefull tips/hints/suggestions from you and apologize if you took my reply differently:bowdown:

Crystal IS like 4'8" or something like that....
FWIW -- I currently use a 13 mm 1/4" drive socket as a restrictor.  I put it against the firewall with no clamp.  That was 3 years ago.  I've had ZERO issues...
