Once I get the old one off, I'm gonna change out the housing out also. Then I'm going to take and make a cad drawing of if, and check, and see how long it would take me to make one. I have Bridgeports,lathes, and almost every machine shop tool known to man. It wouldn't. be worth having it cast. So I'll take a aluminum block and make one. If I can do it cheap enough, I'll let everyone know. After i make the first one and try it, I'll let everyone know. Cut out of a block will not be cheap.

 

If you could make a housing out of aluminum that's plug and play and free of leaks I'd be VERY interested and I'm sure a lot of other people would be too.

 

Just replaced my tstat for that exact reason. no more light and car has great heat again.

 

Well thanks everyone that gave me the guidance and insight as to what needed to be done. I changed the housing(top,& Bottom), thermostat, temp. sensor, & small bypass hoses. Took my OBDII and reset the check engine light. AND ALL IS RIGHT NOW. Car heats up a WHOLE lot better now.
Next I mentioned that I was going to check on the possibility of making the housings out of aluminum. I've the equipment to make them, BUT, I worked it out, and it would be to cost prohibitive to make these. I'm going to make one in my spare time, and I figure it will still take a ton of hours to build. Someone needs to set a casting of these to parts, and then just do the machining, and polishing of the critical areas. I don't have that kind of time.
THANKS TO EVERYONE THAT HELPED ME.
