Engine Cooling problem
1998 Chevy Lumina 6 cyl Front Wheel Drive Automatic
----------------------------------------------------------------



my car started overheating today. I had just replaced the upper intake manifold(pretty proud of that) and i was driving back from a trip when it started overheating. It looked like it was coming from underneath the "pully"(purple arrow) and it was really gushing. when i replaced the uper intake manifold it was clogged with a bunch of orange junk where the coolant was suposed to go threw. this was some pretty thinck junk. after letting it cool down i tryed to drive it home that "pully siezed" and caused my serpintine belt to come off.

my questions are: what is the "pully" could it have caused my car to overheat?

can i drive my car a short distance home without the serpintine belt?

Sounds like the water pump went byebye

tha twas it i fixed it last night. my car still doesnt blow heat I've replaced the thermostat,coolant, water pump, up intake manifold, what else could it be? could that gunk have clogged my whole system?

Heater hoses and heater core could be clogged-up
