? You have 3 threads going on this truck all at once is really confusing the suggestions possible. IDK, HT may be able to combine them or YOU can as I think the #1 problem at another is it's wetting 2 plugs you "think" is coolant and adding coolant.

If that's not solved not much else is going to matter or lead you to fixes that are NOT the source problem - burning or leaking coolant is #1 now forget the rest are likely the result of that,

I'm closing this one now and will be deleting it in the near future.

I already deleted one of the other responses that was turned into a whole new question. I left the one about the 0/2 sensors.

Please make all your responses to your original question/s.
