its a closed system, no cap. Add fluid to the plastic container. You can convert to an open system, but that's not cheap.

the 88 has a 'closed system'... you fill it through the overflow resevior....
Last I heard, there was no such thing as radiator sealant in a commanche. If you have a hole, you need a new radiator. Try tightning down all the hoses first, though.
THE timing on a 88 Comanche w/inline six cyl. is set at the factory and not adjustable.
i have an 88 Comanche and mine is on the driver side underneath the headlights, almost in the wheelwell
If a 1988 Jeep Comanche will not start even though there is spark and the timing seems to be correct and the fuel pressure is good, check the starter solenoid. Even though all the other factors are good, the starter solenoid might not be telling the starter to engage.
My problem on the 88 I was working on turned out to be the crank position sensor located on the driver side top of the bell housing.
The thermostat is quite easy to locate. It is at the top of the engine at the front. You will see a radiator hose attached to the engine at this location. The thermostat is in the housing it attaches to.
This sounds like an earth problem check battery to chassis & chassis to engine earth connections also check earth to alternator best wishes
If you mean the low coolant sensor, it is located on the radiator about 3-4 inches below the cap, it screws into the back side of the radiator. There is also a low washer fluid sensor located in the top of the winshield washer reservior.
yes it will most 70 model jeep thru 95 jeep parts interchange.
If it has the same gearing yes, but I believe all Wranglers (excluding Rubicons) have a rear Dana 35 which is not a desirable axle. I would suggest a '97-'01 Chrysler 8.25 29 spline from a Cherokee. Or if you can find one, they also came with Dana 44's in '87-'88.
Engine, yes. Transmission is different.
