does anybody know the I.D. for the heater hose? going to get a valve and some hose barbs thanks

 

why? whats the mod?

 

to cut the hot water for the heater core so the air is colder coming into the cab.

 

cut the hot water from cert through the heater core.

 

5/8"

A couple pictures that i have collected.
Mine is the first one. Yellow handle.

Others that have posted from FTE that i collected. I forget to whom to give credit.

 

Mine is automatic (vacuum operated valve) using the DieselSite.com kit. Nice bit of kit....

 

Just go to Napa and grab a valve for a 98' Ranger I believe.

 

Here's a LINK to my Photobucket "Colder AC" album. I got the Ranger valve at the dealership cheaper then AutoZone or O'Riellys, but I only paid wholesale.

 

X2 I used Robins Link and it worked great.

 

Damn, that's nice to hear. Thanks Eddie.

 

don't get the flip switch, get the ranger part...i think i have a pic still in my gallery...lemme go get that and post it for you...



there you go...you can see the part number, i got everything at Advance Auto...

do a search for the "Maxx A/C" thread...


EDIT: search for the thread..."Wow...REAL Air Conditioning"...post #6 by the OP gives you a parts list...this really works great...absolutely zero problems to date, installed last summer just after RRE2009...



EDIT:...direct quote from the aforementioned thread...

"You cut both the supply and return lines to the heater core just in front of the firewall. Then install Autozone part # 74809 (it fits a Ford Ranger) heater control valve (the valve works no matter which way it is installed). The valve, when actuated by vacuum cuts the flow of hot water to the heater core and sends it back to the engine. Coonect a vacuum line to the valve and run it through the firewall (there is a plug near the floor which you can get it through without drilling). Pull the rubber bumpers on the glove box inward and the glove box will hang down. Look at the left and you will see a vacuum valve with a bunch of vacuum lines coming to it. Cut the RED hose, put in a vacuum t-fitting and connect the hose from the heater control valve you just installed. Now, any time you move the control on the dash to VENT, AC, or MAX AC the hot water won't flow to the heater core. This will make the AC much colder (some have reported 10-15 degrees colder). I can see many times when I use to have to run AC, I will be able to just run the vent and when I do have to run AC, I can set the thermostat much higher (warmer) and yet be cooler...this mod will pay for itself! Total time for mod: 30-45 minutes...

Parts you will need:

1 - Autozone #74809 heater valve

5' of 3/16" vacuumline

4 - 7/8 or 1" screw clamps

1 - vacuum T-fitting"

 

thanks for the responce guys. the weather here in lake havasu az is like a light switch yesterday was 60 today is going to be 89 only to get hotter. mid summer it does not get lower than 95 at night.

 

You ain't kidding

 

i like the idea of the ranger valve, i have not done it because i did not know how blocking the water would do, but this fixes that.

 

who ever came up with the ranger valve thanks.
