[S10SNODOG]

OK Hello all I have a 2003 S-10 V-6 vortec truck and out of no where this leak that I noticed has occured, It seem's to be leaking from the bottom of the radiator area but when I looked I could not see where it came from and then stopped......... I filled the resevoir and topped off the rediator now it stopped weired I thought it may be coming from the overflow tube from the resevoir so I took off the tube on the overflow and here I am with a gallon of mixed orange antifreeze ready for tomorrows travel to work at 6:00 am thats only 15 min. from home I also noiced that on a trip last night at 65-70 MPH on the parkway out of no were the BATT light came on for 10 sec. and I have a VOLT meter and I belive that was ok at 14 volts but the light went OFF and the today this happend WEIRD STUFF I checked the bottom radiator hose and its ok any help would be greatly appriceatted also the same time I noiticed the leak I opened the drivers door and it made a loud bang/crack and when I looked at the hinge area the top hinge spring I was able to remove it and now theres no spring in the door hinge

Pressure test the coolant system cold and warm and hot.

Watch rad core and tanks and drain plug for leaks.
