Insulated-shielded hose on driver's side exhaust manifold
On a 1998 Chevy S10 V6 4.3l engine what is the insulated-shielded hose running to the driver's side exhaust manifold and is it necessary for the engine to function properly? There isn't one on the passenger side exhaust manifold. I know where the O2 sensor is and it isn't it. A 3/4 inch wrench fits it so I assume it is a 19mm.

You can use a spark tester (on Amazon for $6)A timing light on each wire at a time or measure resistance of each wire.
You can also run a well insulated grounded screw driver along the running vehicles ignition wires and look for any sparks.Otherwise,if the wires are over 10 years old,replace them.On a cold vehicle that has a steady miss,start it and take the temperature of each exhaust port on the exhaust manifold with a lazer temp reader.When you find a cold exhaust port that's the cyl not doing any work.
its on the back of the motor above the transmission its in a very hard spot to see just follow the intake manifold all the way back run your hand down behind the engine and you should feel a wire running down to the switch its twards the driver side of the block it should screw straight down from the top alot of times you can lay ontop of the engine and look back behind the intake and see it
1998 Ford Truck Windstar 3.8L
SFI 6cyl, there are 4 oxygen sensors on the Windstars They are divided into 2
banks of 2. Bank 1 is the for the rear 3 cylinders of the engine - Bank 2
is for the front 3 cylinders.
Bank 1 / Sensor 1 (upstream) is located just below, in the pipe,
the exhaust manifold on the back of the engine.
REMOVE TIP: you may have to bend part of
the transmission heat shield out of the way - be sure to put it back
when done. Bank 1 Sensor 2 (downstream) is located just past the drivers
side catalytic converter. Bank 2 Sensor 1 (upstream) is located just below the exhaust
manifold, in the pipe, at the front of the van - access is from the top. Bank 2 Sensor 2 (downstream) sensor is located just past the
passenger side catalytic converter.
* Use lots of penetrating oil - allow to soak - to make
removal easier and avoid damaging the exhaust pipe
Hope this help; TY for using Fixya (remember rated and comment this).
I think its insulated to keep the heat from the exhaust off of it. It does not need any loop. Its kind of hard the imagine what this looks like.
But, if it was mine I would cut off the old wire and make a new wire and connection. Use the same size wire as Chevy used and run the new wire with no loops. Just make sure you keep the wire (Any Wires) away from the exhaust pipe.
I hope this helps you and your 62.
hi im wes
it il located under the water outlet follow your radiator hose to the water outlet it has the radiator hose and 2 smaller hoses on it remove the two bolts holding the housing on remove and replace the thermastat paying attention to what way it faces make sure to replace the rubber oring retighten bolts and refill with fluid run for a few refill fluids hope this helps thanks wes
ps please rate me
Just changed a starter in a 94 S10 4x4. The only way to remove the starter was to take the passenger side exhaust manifold off and bring the starter out that way. Installation the same in reverse. Hope this helps. Don
