WHAT COULD THIS BE?? Cooling issue...

**** guys, lets stay on topic here. The pcm is the least of my worries....
the truck runs fine,
drives until it hits operating temp then suddenly the heater stops working, truck goes to overheat. I turn it off and go to the radiator, take the cap off and it lets a whole ****load of air out....the reservoir outside is full so i fill all of that into the radiator. Put the cap back on and keep driving and it works great. after a little while its the identical thing again...it pushes all of the water into the reservoir and then overheats. put the water back and its fine....what the hell could it be.

neattouch, i have the same exact problem with my dakota. it would be great if you posted the results. i compression tested last night and all seems to be fine. i have random overheating and random missfire in cylinder number two. i thnking that may the truck wasnt hot enough to open what ever crack or leak there is..

I gotta say something, OK first off Augie man seriously theres not a damn thing that river running and mudding or tugging will to do hurt a truck. Thats why we spend the money on these trucks. why would you spend 3 grand on a 5 - 7 inch lift kit and never take it offroad or in the swamps or mud. if you dont you're simply a poser and need to take your ball an run home to mommy cause the big boys are out to play.
I have had my truck buried and i mean BURIED up to the windows in mud, and yes i stalled out. i knew i would but i also knew i could get pulled out an hosed down. once i got out it fired right up, ran like crap for about an hour untill i washed the engine down an the destrib dried out..
Long story short.. it's a truck, it's ment to take the abuse. if you dont want to take a chance of getting stuck or brused up your better off buying a kia..

I offroad however I also understand my truck wasnt designed to run through creeks and rivers.. if it was the pcm would be waterproofed as well as electrical connections and it would likely have a snorkle to keep the water out of the engine (yes they are not just for looks).... driving through deep water without it or at high speeds is a good way to hydrolock the motor and trash it...do a search and you see a thread where one person did it just driving through a deep puddle in the road from a backed up storm drain...its not likely in that case but possible.
I had a jeep wrangler and did my fair share of offroading it it...I also messed a lot of things up with mud and water like my alarm system my fuel gauge and I even dropped my engine right out onto the sand dunes at the beach.... all of this was my fault due to me "thinking they were designed for it"
