Overheat

[STR864]

ok...that is what I checked...I thought the water pump was new b/c when I bought the older motor the guy told me he had just put it on...I only put probably 800 miles on that motor before I bought this crate....now I ran the car without the radiator cap on it and it just sitting there and there was nooo circulation....in matter of fact it started to overflow a little bit.....someone also told me it could be because this year motor it needed a overflow tank so it could push out and take back in what it didn't need...so I also have one of those.....there is also no thermostat in it....I don't have air in my car so I figured a complete flow of water would do the motor just fine....
