I don't know---does it? Get literate!
Have the heater core flushed. It might be plugged up with corrosion and dirt.
Perhaps heat shield on catalytic converter?
Pull the gauge cluster out and use a low volt solder iron, and re-solder the points where it plugs in to the cluster, just heat it until the solder starts to melt.
Every vehicle gets hot to the touch, it doesnt mean that your over heating or anything... a Plymouth Voyager gets 195 Degrees. the heat is actually better for the invironment then when the engine is cold because the heat helps burn all gases and keeps it from the air.
On my 94 voyager with the 3.0L the cylinder numbers are stamped into the heat shield located under the spark plug boots - you won't see these numbers with the wires on, since it obscures the stamping. On my van sequence from Left to right is: Front 2-4-6, Rear 1-3-5.
it works by electricity and heat
check your water...
Voyager 1 uses radioisotope thermolectric batteries, powered by the heat generated from the decay of a radioactive substance. In this case, plutonium oxide.
