Engine Diagram - '91 4.0 HO


Recommended Posts

Hi all, I put this simple sketch together for the engine bay of my '91 4.0. It's very basic and it will be common knowledge to most people, but these sorts of diagrams really helped me out when I started working on my JK. If anything needs to be changed or should be added let me know :thumbsup: happy to do more if it helps out anyone. 

 

Edit: thanks @Minuit for the MAP Sensor, AC Expansion Valve and ECU suggestions

A few things you might add:

 

The ECU is the black box on the far right next to the air intake. (for HOs only, the Renix trucks have it inside)

The A/C expansion valve is the metal rectangle next to the heater core pipes.

The MAP sensor is on the firewall to the right of the "hump"

Will get this done -- sorry for the delay! The MAP sensor has the green plastic, correct? And the A/C expansion valve I imagine is the box covered in mud to the left of the firewall? haha
