Question about 1989 Jeep Wrangler

1 Answer

I need a drawing of hoses (pcv solenoids on top of engine)

I recently rebuilt a 1987 Jeep Wrangler. I need a drawing ..preferably in color of the hoses which go to small solenoid switches on top of the rocker cover..(upstream ..downstream is what the catolog says but I cant dtermine where they go. The hoses go to various places on the engine like the carburator ..exhaust , egr valve etc .. there are some places I have not connected to because I am not sure where they go..

Do you a drawing like this ? Thanks

SOURCE: How many upstream and downstream

Hello;
Depending on the engine, there will usually be four o2 sensors. They are easy to identify when you get under the car. Follow the exhaust tube from the exhaust manifold down the pipes. You will see a sensor with leads on it screwed into the pipe.
Thanks;

SOURCE: replace oxygen sensors

these engines have 1 upstream o2 sensor and 1 downstream o2 sensor..the 1 in the rear exhaust manifold is the upstream and the 1 after the converter is the downstream..make sure you replaced the right one

1/1 is upstream sensor on the number 1 cylinder side, 1/2 is the downstream of the number 1 cylinder side, 2/1 is the upstream of the number 2 cylinder side, 2/2 is the downstream of the number 2 cylinder side. Hope this helps.

89 jeep wrangler only blws air out of the defrost vents no matter what position the switch is on


there is a small vacuum hose that goes into the passenger side firewall under the hood into the passenger compartment side-check to see if that is hooked up, it starts on the top of the engine and ends up at your climate controller. You can also drop your glover box down to see behind it to see the hose's route to the climate controller.

Gas is not getting from gas tank to Carburator .. 1987/88 Wrangler 42. engine was recently rebuilt .. gas tank sending unit was removed and repaired .. fuel line was blown out with air compressor. fuel...


Make sure you have the lines attached correctly on the sending unit and make sure there no small holes in the line. The pump pulls fuel and will draw in air. To make sure the pump is good, attach the tank side to a container of fuel and see if the engine starts. (keep the container below the pump or it can start a siphon and appear to be OK when it's not)
If the repair to the sender involved soldering up a line leak, make sure the line is not still leaking and that the line has not filled with solder.
It's a really simple system...there are no "trick" items there. If everything is intact and the pump is good, it has to work!!!

The front axle connects 4wd by vacuum. check the vacuum hoses that run to the actuator. Pay close attention to the vacuum hoses running underneath the battery as battery acid can eat thru those hose easily. Good Luck.

The tube that comes out of the top of the valve cover is your pcv.
The grommet that it goes into gets blocked.
