Howdy, Howdy, Howdy...
I'm replacing the Heater Core on a 1992 Chevy Lumina. Pretty easy but
there are two problems...that I'd appreciate a little advice on.
How does one grab and release the spring clamp on the Heater core
inlet and outlet hoses. I can't seem to reach them with anything (a longer
arm would help) and the clamp ends are so close to each other that I can't
grab them with a vise grip or hose clamp pliers. Do you techs use a special
tool or a very long handled needle nose?
#2 ... one hose has a quick disconnect fitting on the end, connecting onto
an engine pipe. Is there a special tool or method for removing this ??
Thanking you in advance....
Yep, I use a special tool that is designed to hook onto those spring
clamps. In really tight quarters, there is another tool that basically is
the same as the one I have, but it has long flexible cables. You can
hook it onto the spring clamp and then release the tension on the
clamp from a more comfortable position. I used to use regular
pliers, but they don't work well, and you can also damage the
spring clamp so that it does not have the correct tension when
Here is a picture of what these tools look like:
Usually...you can just press the two plastic tangs toward the pipe
and remove the quick connect. If you look closely at the connection,
you can figure out how it works.
Thanks for providing the information Ian...... it helps alot....
I appreciate that you the time to help out an amateur, I find
that working on cars (as a hobby) is fun, but it sometimes gets
so frustrating when one doesn't have the information or the
hints and tips that make the job go smoothly.
Thanks again for taking the time to share your knowledge !!

No problem.....I understand completely..I'm always amazed
that amateur techs can get so much done. If I had to work
with less then good conditions and tools, I'd probably rather
not. Of course, I'm quite lazy by nature...(grin)
This is an APV (mini van) ..... the clamps are way down on the fireware between
tower and the engine. Not a lot of clearance, plus the original spring clamps
oriented so that the arms are blocking acess . Can't access them from
down under either. Ian suggested the best tool for the job where the access
extremely limited. (working smarter not harder ).
I'm replacing both inlet and outlet hoses as they probably are original and
years old. Time for replacement. This means disconnecting the
quick disconnect coupling without creating additional problems for myself. (or
Thanks.... ( I don't have the heater core out yet.... but it's probably brass.
is pretty good for a heater core.). Hope the plastic replacement lasts as
if it doesn't, the next time I do this will be easier, thanks to the lessons
this time around !!!
I doubt like hell your heater core is brass.
Plastic tanks and aluminum core is more like it. Very common to break
the pipes off the tanks trying to remove hoses in tight spaces that are
welded on after twelve years..
Best Of Luck
