Default Help!!!! cooling probs

Well the camaro has been overheating lately and i couldnt figure it out so i took it to a shop and they said its not circulating coolant at all and heats up quick!!! What the hell could have happened? Could something have broken off causing the pump to not turn? BTW A new pump wasd put on 1 week before this garbage started happening

help guys

Check your thermostat. Your pump is driven off the cam by a drive gear. There is a coupler that goes in between the drive gear that protrudes out of the timing cover and the gear in the back of the water pump. If you forget that coupler, no water will circulate. Same goes with a thermostat that is stuck closed.

See #39 here:

was the air bled from your cooling system after the new WP was installed? If not, you'll get crazy-fast overheating when you come across an air pocket. I'm pretty sure shoebox's website has detailed instructions on how to bleed the system of air.

+1 on check the coupler. It can get stripped inside. Also the tit coming off the waterpump drive gear going into the coupler can break. EWP is a good mod.
