Getting to Know Your Jeep
A lot of the questions on this board are generated because someone thinks something is wrong with their jeep....with one of the common ones being how hot is too hot.
I'm a firm believer in getting under the jeep and looking at things...taking pictures..etc. When I did my SBC swap, it took plenty of pics of the jeep as I tore it apart...those came in handy as I started putting it back together.
Now that the swap is done and I'm driving it, I need to figure out my baseline...in other words, what is ok and what is not. I changed a lot of things and I want to make sure that I'm not running borderline on something.
Take this morning...I hooked up my OBDI scanner and monitored my engine temp while I drove to work. I did both fwy and city streets and I did not turn on my electric fan. I realized real quick that the engine has the wrong t-stat in it...on the fwy it never got over 184. I can tell when the t-stat opens because I get a warm blast of up up through the big hole where the tranny is. This 186 might explain why I think my MPG is not where I thought it should be. It was also good to see that I never got over 200 deg on the street while sitting at lights and the fan not running...it also means that my stock CJ temp gauge is basically about right.
I am also carrying around a 2 gal jug of gas...and letting my tank run dry...I want to see where my gas gauge really reads when I run out of gas....and I want to see how well that electric fuel pump mounted on the frame rail will operate at these low fuel levels...including re-priming the fuel system when I run out.
All part of getting to know my jeep......
