Ok my car over heated again today and blew all the coolant out of the hose that connects the resevoir to the radiator cap.

3 days ago i removed the thermostat and it ran fine for a few days.. Then on my way home it over heats while going down the highway.

Luckily i had a spare jug of water with me just incase so i filled it back up and drove it home (15 miles) without the temp going above normal.

Ive never heard of a water pump going out like this... stops working... starts working.. stops... starts...

Unless its the radiator for some reason..

Fans work fine (it overheated on the highway)
No coolant is leaking out (overheating/blowing out)
Am i missing something?

Recommendation on low priced seller for a water pump. And possibly someone to install it. How many hours do u think it takes to install it? I thinking 2.
