You may have torx head screws there, like on a '95 cherokee: size t-30 for the radiator bracket, and oddly enough, the hood latch piece there was also torx head, but sized t-27.

you have a faulty thermostat in your jeep. the thermostat is on the engine where the top cooling hose attaches to the motor. it will look like a small valve type thing with a spring that holds the brass part against the steel. if you are replacing this yourself than you will want a 195 thermostat.

Bypass is simple. Remove both hoses at the firewall where they connect to the heater core. Install a four inch piece of half inch copper pipe between the hoses and use screw type clamps to tighten it up.
If you don't let the hoses drop down while you are working you won't loose much coolant (probably about a cup or so) but check level anyhow after running it for a few minutes.

You can use either the grees stuff or Dexcool (red)-50/50 mix.

elizabeth700:

Most likely a small evaporative leak will be from the gas cap. Replace the cap, then leave your battery unhooked for about a half hour to clear the code.

I find I have to replace my cap every couple of years.

A high oil pressure reading is a good thing, low oil pressure is something to worry about. Normally with a cold start, your oil pressure will remain high until the engine has reached operating temperature, then drop a bit, but again, high oil pressure readings are a good sign of a healthy engine. One other factor to consider is the viscosity of your oil, if your engine uses 5w30 and you switch it to a higher viscosity such as 10w40, you may also see higher oil pressure readings, so be sure you are using the correct oil for your vehicle. I hope this has helped you! :)
