MG TD TF 1500 - TD Water pressure?

I did a search on the archives and couldn't find anything. Can anyone tell me the proper(?) water pressure in a TD? I'm looking for a 12v solenoid water valve and want to make sure it's big enough to handle the gpm rates and pressure created by the water pump.
Thanks in advance!

As far as I know there is no water pressure as the cooling system is an "open" system. The TF has a pressured system.

Geof,
CR is correct,,, a stock TD system is not pressurized,,,

You'll be doing yourself a favor by sticking with a cheap ball valve. You'd need a good sized solenoid valve so as not to restrict flow but you'll also tack on another parasitic draw onto your generator. You're electrical system doesn't need any unnecessary accessories.
The TD does not have a pressurized system.

There is no real measurable pressure to speak of produced by the water pump (a fraction of 1 psi), and the flow (obviously depending on rpm) is probably in the neighborhood of 1-10 gallons per minute.

Can't quite be that way, C.R. Those laws of physics still hold to move something, the old F=MA bit. I've never seen the figure, but it can't be very high. Bud

good enough; sounds like most any 12v valve should do.
Geoffrey M Baker

The pressure created by the pump depends on the restriction of the thermostat, which must not be taken out. If the thermostat is removed cavitation of the impeller blades will happen at high speeds.

Bud... Those pesky physics formulas. (Grin)

Thought you'd appreciate that one, C.R. Bud
