I have a Chevy Suburban that I'm going to replace the rear heater core
(leaks) but I have to disconnect the heater hose quick connects to it to
remove it. I've tried to purchase a tool to separate the quick connects but
no auto part stores in the greater Los Angeles metropolitan area have it and
most don't know what I'm talking about. My GM service manual says I need a
special tool (J 38723) but none of the 5 GM dealers that I contacted carry
tools to sell. Any recommendations would be greatly appreciated.
Get rid of this quick-disconnect set-up all together. Almost everyone
I know that has this type of QD set-up at the intake manifold has had
problems with either leakage or breakage of the fitting with the hose
into it or the soft metal fitting breaking at the intake eventually.
If your heater hose connects to the rear of the manifold and it breaks
you will be cussing at GM at what it takes to repair it if the fitting
breaks off flush into the manifold.
Just go to the hardware store and get a brass adapter and hose
fitting to install the heater hose to it. Works great and last long
My 2 cents for what it's worth.
Yep, can hardly wait to take the one off my '99 Suburban's intake manifold.
I postponed it this fall as it just crusts over a little, but will probably
have to face the inevitable this Spring. Why, oh why couldn't it be in the
water pump, an inexpensive pump at that as was on my '95 Yukon 5.7 L TBI
engine, and not some outrageously expensive pump like on the Vortec!!! It
broke in that pump and I simply replaced the pump and fitting with hardly
any time/effort and everything was good as new at 75K miles. No more
