Re: Lincoln Cooling Fan
That makes sense & is the easiest fix. I'll start with the thermostat this weekend. Thanks Lee!

Re: Lincoln Cooling Fan
I think it said on the Holley site that the water neck could be clocked. It might be as simples as the actual thermostat vent hole being at the bottom so there is a bubble in the housing and is no water flow around the thermostat body to heat it up in time

Re: Lincoln Cooling Fan
Crossed the thermostat off the list, it works fine. Tested it this weekend.

Re: Lincoln Cooling Fan
the LS engine coolant flows through the rad and butts against the closed thermostat (until it opens) at the engine coolant intake of the water pump then, when the engine heats up, coolant flows. you wouldn't see flow in the rad until this point. the old small block way was flow through the thermostat from the engine outlet side, not the intake side.
either way, no flow through rad until thermostat opens. flow through heater hose all the time. check out this link for an in depth look at cooling system, steam lines etc. LS specific http://www.billavista.com/tech/Artic...ble/index.html |

Re: Lincoln Cooling Fan

Re: Lincoln Cooling Fan
yup, it is a good read for somebody who is building and is unfamiliar with how the LS system works.
hopefully it will help somebody |

Re: Lincoln Cooling Fan
Pull the thermostat. out leave it out
Put the lower hose back on and stick a garden hose in the fill of radiator. Take off the top fill hose and leave over top of radiator. (tie it off so does not fall into mechanicals) Fire it up let it run and see how much flow your actually getting thru the system. it should hardly get up to operating temp with the constant flow of cold water in system. That will tell you a lot. you can even measure gallons per minute in a five gallon bucket. |
