I was tearing around the engine and came upon few things I couldn't solve on my own trough the FSM.


Here is a picture of the two secondary injector harness, what I need to know is what is this third wire set that is insulated the same way as the injector harness. The third set has two wires and does not have any connectors.


This picture shows the top of the center section, this looks like it leads to the water jackets. I wonder what its purpose was?


This picture shows again the top of center section near the oil cap, this one shows a coolant hose coming of the center section, its currently blocked off, where is it supposed to go to?

 

2nd picture - EGR VALVE
3rd Picture - That is for the PCV system. Should go to your hard lines on the firewall which lead to the evap canister.

 

Thanks.

 

If I see that 3rd picture right, you have a coolant hose dumping coolant into your crankcase.

 

good call!
If that hose is coming from the Heater core on the firewall,then it should NOT be connected to the Oil Filler tube.
It connects on the side of the engine(I believe).The coolant pipe should be Drivers side engine.

 

I said in the description of pic 3 that currently that the hose you are seeing is blocked. Its blocked with a screw and a clamp (ghetto rigged)

 

I see a fram filter......

 

Heck yes......changed the oil last night.

 

The third set of wires near the two injector plugs........is probably the water thermo sensor wires. One will be green/white if so. See manual.

 

The color of one of the two wires is green/white. For some time I've been puzzled as to why it would be tied to one of the injector wires appearing identical. Thanks for the tip I will look into it.

 

Edit: I cant seem to find the location of the thermo sensor.... Its confusing, the car has 3 sensors to read coolant tmep. There is one located at the bottom of the radiator, one on the upper radiator return line (fan switch). But no sign of the thermo switch, would it be tapped into the housing block?

 

It's on top and behind the water pump.
