Evans WATERLESS Coolant

[Excaliber]

My system holds 4 gallons and it expands a bunch all right! An overflow tank is a must have (and I do have one) for this conversion. So far, at this point with mild weather, I can't see any substantial difference between Evans and water (as far as cooling capacity goes). This time of year I would normally have drained the water and re-filled with antifreeze anyway.

Glad to hear things went well.

Ernie, get a radiator cap for a farm tractor. They're typically 4~7 psi.

Here's a 7psi: http://cgi.ebay.com/ford-tractor-rad...item5194ca84a0

Here's a 4psi: http://cgi.ebay.com/Radiator-Cap-Int...item58873ffa97

Although if your not seeing any issues, I'd keep it at zero pressure.
