I have a 91 taurus wagon. Recently I had some work done on the
engine. Lately, I noticed a noise. I looked around and found that a
5/8" heater hose had burned through. The hose connects a short
upright pipe coming up from what looks like a manifold to a longish
horizontal pipe that goes right to left at the rear of the engine.
The hose was about 6 inches long. The location of this assembly is the
left rear of the engine compartment when facing the engine from the
I went to the auto supply and got a length of heater hose and
connected it with the two hose clamps. I started the car and the
noise seemed to disappear. Great. I went for a short trip and when I
was returning home, I heard the noise again. When I got home, I
popped the hood and sure enough, the new hose had a hole burned in it.
So my question is, is it normal for that kind of heat to be present at
that location and do I need a special kind of hose that will contain
Any help is really appreciated. Thanks, bill
Just wondering something,did you get the work done by a reputable
Its sounds as though a heat riser has been modofied. This riser may be
used to acctuate the choke mechanism if this model is carbed.
You may also want to check,if this hose is part of the heating system if
you have a blockage in the heater core.

Well, the noise sounds like a tapping that could very well be exhaust
noise. And, remember, after the hose I put on was connected, and
before the new one I put on burned through, it had silenced the noise.
So. I would think it was perhaps exhaust rather than engine.
What is the EGR system? (I am obviously not a mechanic.)
If so, what is the likely solution? Do I need a special, "non-rubber"
hose, or something?
What is the EGR system, anyway? (I am obviously not a mechanic.)
Exhaust gas recirculation, emissions lowering (and necessary).
Call or shop around.. suggest NAPA.. for a suitable replacement.
If you find it, take it back to that shop, insist they install it for
free. WHILE YOU WATCH. Or just do it yourself then go have a talk with
the shop manager
It really sounds like the steel tube from the exhaust manifold to the EGR
been patched with rubber or silicone hose. The entire tube should be replaced.
used to be silicone hose repair kits for AIR tubes but they won't stand up to
of hot exhaust gas flowing through thr EGR tube.
that tube is a air injection system for the catalytic converter most
likely... was a there an air pump on car ? you may have a problem with
the control valve on the air pump.... some cars had a one way check
valve on this pipe ...... if this has one and its stuck open exhaust
will back up he pipe and burn the hose.
