hopefully its not that, im gona try the other stuff first, head gasket check and so on.....

to cold out to be f-n with this car
glad its not my daily

boostman101

well, i did the radiator cap test....no little bubbles.
also no mixture with oil.
also drove the car for about 40 minutes, let her warm up for about 20minutes.
she drove fine the needle went up a lil but not near the Hot mark.
it went up a lil then went back down, didnt go back up.
got home check the over flow tank and it was filled again.
but i also notice that the top rad. hose was HOT, while the bottom hose was COLD, also the top portion of the radiator was hot and the bottom portion of the radiator was cool. dont get me wrong but i dont think thats right, that explains why it boils over into the over flow tank, could it be clugged or a sticking thermostat

i had overheating problems, i flushed the radiator, new thermostat, new radiator fan switch, a big mess and it still overheated after i got on it hard a few times. i fixed it by stripping the radiator fan switch cables(it's the sensor that's on top of the thermostat)it has 2 cables. i stripped them without cutting, just pulling the plastic insulator on both cables back with a cutter and twisteing the cables together so the wires make contact with each other and then covering them with tape. this makes your radiator fan turn on constantly without stopping as soon as the ignition is turned on. this solved my overheating problem. i tried this without a thermostat and the car operated way to cold so i put the thermostat back in and now it's ok.

Well the car doesn’t really over heat it just goes to the normal spot (between Cold and Hot) then once the over flow tank fills it will go up a little like ¾’s but then go back to the normal spot.
Plus like I said the top hose gets baking hot while the bottom hose is cold, and I mean cold.

also thanks for all the help folks.

im gona give the easiest thing a try first, which is change the thermostat, it my be broken (last one fell apart in the housing, spring and everything was hanging off)
Cause the car drives fine, I mean its been doing this for like 2 weeks, and the oil pressure and every things great, car drives the same way, no power lost, no hard starts no cutting off or anything. Did the head gasket tests, seems fine, thermostat test is a negative tho….dont kno about the sleeves, guess the last thing ill check. Can also try that thermo sensor, I had to replace that because the one before cracked, so I wired up another one, might have came loose, but ill see, its just cold as hell outside and I don’t feel like banging my hands and dealing with cold tools…lol

i had the same thing happen to me on a all-motor D-series. I changed the radiator cap and it didnt help but changing the headgasket fixed it. Mine would over heat when too much coolant ran out of the overflow tank

in order to check the head gasket you need to take the head off too

i had the same problem in the summer when i wasnt boosting, my fan wasnt coming on and my car would overheat, anyways i fixed the fan, the overheating stopped and my coolant tank stopped over flowing, shrug!

Your water pump could be bad. That's what fixed mine. Temp needle would go up and down and up and down and the overflow was literally overflowing... Replaced the rad. cap and thermostat as well. Burped all the air out too and it runs like a champ.

well i found another issue....

while checking my thermostat and just messing around with things.
i notice (i start the car, had the cap off) that the radiator, right where the plastci top part (black section) connects to the fin section, there was a leak, it was small but....wasnt like ur regular leak.
i was more like a domino affect. one section would filled or leak coolant, then the next section would follow, then so on. so i change the radiator, thru in a 160 degree thermostat and now im wating for my 1.3bar cap, so we'll see what this does, if nuffin, then im just gona change the headgasket....anyone of u done or hear about double-n up on the head gasket

ok heres just a few thoughts.... if u say the top of the rad. is hot, but the bottom is cold(is ur bottom hose pressurized,what about the top one, is it pressurized?), then u might have a clogged radiattor. id try doing a compression test, try finding a different radiator or a new cap(i think u said u did or where going to try that). befor i took the motor apart.
