Going Through a Beater XJ 4.0.

Used my old smog machine of 30 years, to check for head gasket leaks into the cooling system. This machine is super sensitive to exhaust emissions. Although I had to do a lot of repair work to the machine first. Now it runs great.

The MT2500 Scanner made it obvious that the O2 sensor was bad. I'll double check the sensor wiring too make sure.

The XJ overheats easily. Engine compartment is coated in rust. I'll probably rod out the radiator.

Here is the video I shot of sniffing the overflow tank, and shooting temps of the radiator tanks.
