Is there a special reason why the heater valve has to be in the side pod?
It seems to be making life really difficult if the valve fails or the pipes leak. I think it could be under the dash or in the engine bay.
Any thoughts.

You're absolutely right.

Yes there is a reason why it's not under the dash.
The pipes have a tee piece on the rear bulk head (Engine side) that stops anypressure build up in the heater system when the engine Thermostate is closed along with the heater valve, but there will still be a pressure build up of some kind. The posability of a heater pipe blowing off could cause major burn to passenger/driver, or even crash while driving. So any conections that could be took out of the cabin is best, even if it's in side pod.
Have fun..

Your comments reminded me of an aquaintance of mine from back in the mid 80's. He was a good guy and an excellent pilot to boot. While flying his North American P51 Mustang on approach the plane suddenly started to vascillate in pitch and roll and at about a half mile out pitched down an crashed violently killing him. The final accident report disclosed that the lines from the radiator to the engine(the Mustang has a belly scoop radiator) which run under the pilot had burst and he was scalded nearly to death before he lost control and crashed. Probably not the same as the heater lines.....but as for me......mines going in the side pod.

Mine will be in the engine compartment for the reasons stated above.

This topic is a great example of the beauty of this forum. It gives the readers and builders a chance to exchange ideas and reasons for the path in which we plan to direct our construction.
I have to admit, that when I located the heater valve where I did, I never thought about the problem of the valve coming apart, as a matter of fact, I was thinking just the opposite, how would I ever get the hoses off if I ever had to.
Brought the subject up this morning at the Saturday meeting of gearheads over coffee and donuts.
Our total years of working around autos totals over two centuries, and none of us could ever remember a heater hose coming off. We did however remember having to change a heater valve.
Had I put the valve in the luggage pod, I was sure of two things;
1. all the carpet and contents would get wet in case of a leaking valve,
2. and I would probably have to take the cill cover off in order to get the hoses off the valve.
Once again, this is the beauty of building our own cars and incorporating our ideas, and the way we think will work the best for us.
At this time, I'm sorry I can't post a picture of my setup with the safety features that are in place to secure the hoses, but we are working on a web site which should be up within the month.
As a follow up, I'd like to say that this is a setup that I'm comfortable with, and in no way am I trying to convince anyone that this is best for them.
Happy Building
Jack

Well said! I agree 100%. That's not only the great thing about the forum but also one of the best things about building an Ultima. We all have opinions and personal prefferences and are free to build as our heart desires. Beats the hell out of anything out of Detroit!
