Got my car back together yesterday, and drove it some today and when i get on it hard, the temperature hand pegs pretty much.... I replaced the sender to make sure that wasn't the problem because its amazing how fast it gets hot... The motor at idle is pumping water out of the top hose... The engine stays cool as long under regular driving... But when its run hard just in first gear, the temp hand will go from the n in normal to the r and then it just continues to peg within 20 seconds.... I got out and looked under the hood and both radiator hoses were collapsed... It was spilling coolant out of the resevoir.... Anyone have any idea what it is...New water pump on it also...

hmmm not sure, but when I installed my radiator hoses, I took some thick, but bendable wire and made some coils that fit inside the hose to keep them from collapsing

sounds like a grounding issue... the sensors i mean.


add a ground wire from your chasis to your block, that problem should go away!

Well there wasn't any water in the water outlet on the intake...The thermostat was wide open and no water... If it was the sensors, there still should be some water right? The block is g rounded, but i can run another one on it... All the sensors are working cuz it idles and everything, but who knows....****ty feeling cuz i finally got it back together and seems to run pretty good, but as soon as i get on it hard, it goes to red... Also, there is no water going into the bypass for the heater core, the engine was red hot, the bottom hose hot, top hose cold, and the heater hoses cold... But the thermostat was open...
