I ordered this coolant over flow tank today from summit racing, My dart being that its a brand new 318 having a new radiator new cooling flex fan it still after being ran for a 15 mile drive on an average nice day after i shut it off i have coolant coming from the spout under the cap its really starting annoy me. so i bought this help solve the problem.
what do you guys think can be causing this over spill problem?

 

try a 180* thermostate and see if that helps

 

coolant overflowing is common
it will always happen

 

Thanks for the input guys but im a dumby and did some research and after i had a the radiator put in. It had a 14 PSI cap on and i read they need a 16 lb cap and it stopped the little overflow but im putting in the overflow tank anyways, i have a couple dogs and they might lick the coolant on the ground so im taking the proper percautions.

 

my -

Glad you got it figured out. Now a question: does that "puke can" have the radiator inlet in the top or bottom and if the bottom, does it have a fill cap on top?

Thanks

Hey Archer,
the inlet line is on the top with no cap, with a petcock drain on the bottom.

 

Get rid of that flex fan.
