First Major Problem

right at the 3K mile mark since i have got her runnin. Something goes wrong. Water. and Overheat. At first. A small leak at water inlet house. One night, go to freinds house. got out. and radiator hose was pulseing. found out i was just about out of water. But car did not overheat. Filled the radiator up. and resavor. Drove it 15 miles. I lost the full resavor. and half the radiator. I stayed up late that night siliconing the water inlet house. Next drive. This mornin. I was goin to work. Made it 14 miles when water light came on. **** load of steam came from under the hood. and she started to over heat. So i pull over. Coolant was everywhere. I refilled it(i carryed some with me) Tryed to start. and the batt was dead. Lucky, i stoped at top of a hill. Good push. put in 1st. droped clutch. she fired right up. Drove her home. a lil steam. but not much. She tryed to overheat. but then the temp would drop back down. then go back to normal. then try to overheat. then drop back down. then back to normal. I made it home with out overheating or looseing all my water. Today i replaced Both water inlet house gaskets. and thermo. Drove it. in 5 miles i lost a full resavor. and some steam. Before i drove it when i did new gaskets. i let it sit at idle for 15 mins to let it warm up. No drips. no water anywhere. The Coolant is going somewhere. But i can't find a leak. and the car don't smell, or smoke. so where is it going at that rapid of a rate?

you push start cars in second gear.... DUH!!!! but seriously you do its better.

its probably leaking out of the resicvour teh radiator its self or a lower hose... some where where its just going and hiting the ground so it isnt collecting in the engine bay.. check your rad... all the hoses... and maybe even your heater core....

is the water pump leaking? they can leak out, and you never know it, right out of the front seal. or check your rad tanks, those leak sometimes too.

Fub... it sounds like your water pump isn't working (spinning) correctly, or your thermostat is stuck shut. Getting it hot more than once is enough to kill your cylinder head too.

So...

-Is the water pump spinning freely when running?

-Did you install a new thermostat?

-If the battery had enough juice to start the car... then it overheated & the battery was toast... something might be going on w/ the belt (as the alternator & water pump use the same belt).

Pressure test the coolant system. You'll hear the bubbling or hissing wherever the leak is.
