Anyway she fired right up and sounded fine. It's a chevy tall deck 427. It was cool today so I let it warm up for 10 minutes or so. Well after 10 minutes the guage read 240 and water was coming out of the rad. Why would it over heat so fast?<hr size="1"/><b>Re: Over heating</b><br/>Post by gimpyrobb on Oct 29, 2006, 8:12pm<br/><br/>Water pump?<hr size="1"/><b>Re: Over heating</b><br/>Post by Barrman on Oct 30, 2006, 9:57am<br/><br/>Water pump or stuck closed thermostat as a second guess. Of course, how much water was in it from the start?<hr size="1"/><b>Re: Over heating</b><br/>Post by porkchop on Oct 30, 2006, 10:22am<br/><br/>I would say stuck thermostat, since you have ran it in awhile.<hr size="1"/><b>Re: Over heating</b><br/>Post by jeepcj on Oct 30, 2006, 2:58pm<br/><br/>The rad was full right to the top<hr size="1"/><b>Re: Over heating</b><br/>Post by Swampthang on Nov 2, 2006, 1:21am<br/><br/>427's actually have two thermostats side by side. If one is open while the other is stuck, it might allow enough coolant to circulate so that it appears to be flowing back to the radiator and yet not be moving enough water to cool the engine.<hr size="1"/>
