Ok, I know there are alot of threads about cooling on here, but I couldn't find the answer....I think I know what the problem is, but I'm looking for conformation or other points of view.....so, here goes.
My jeep had been hacked from the previous owner, so the heater core was missing, so they bypassed it, and I thought my preasure bottle was cracked because it would heat up fast, as in, fire it up and not even get one mile from the driveway and she's hittin 240....the fluid in the preasure bottle would boil, so my thought is that my preasure botle is cracked or there is a leak in the system and not holding preasure, causeing it to boil at a lower temp.
So, since my system was hacked up and I thought I needed to replace the bottle, and I hate "burping" the system, I converted it to an "open" system this way: http://www.geocities.com/bigbadxj/Open_System_Switch/open_system_switch.html
I cut into my upper hose, and had no water in it at all! Installed everhting and filled up the system, it took about 3/4 of a gallon of distilled water...I fired it up and let it idle, in about 6 minutes of idleing the temp guage read 240 and still climbing, so I shut it off. While it was idleing I was watching, and even though the motor got hot, no water ever expanded into the overflow bottle (mine is white, unlike the one in the link). I checked the upper radiator hose, its got preasure on it, but its cold! I put my hand on the radiator and it also is cold! I crack the cap, the preasure is released into the overflow bottle, I remove the cap and the water inside is clear, so obviously it didnot mix with the other coolant (what was left in the preasure bottle and hoses was obviously green)....further inspection is that the water pump is brand new (installed my previous owner) So, my thought is that he put the wrong pump on and it is flowing backwards, so all the water I poured in, was preasurized against the thermostat, and water is being traped in the block and heating up fast.
Wow, I wrote alot.
Any opinions are welcome.
Thanks,
Justin
