Heres a How to video that Trey made.

 

That is the one I was referring to...with four port for cutting and redirecting both hoses.

 

trey spooner has a nice youtube video of the heater core block off believe he uses a ford ranger valve ....check it out believe its called the max ac mod

 

In my video I use a two hose valve to continue flow. This is a valve from a ranger. from the factory ford used a different valve, that only uses one hose.

The heater core is not apart of the necessary route of coolant for the engine, just an accessory pathway, from the block, to the heater core, and back to the system through the water pump. Cutting off one hose, simply stops the flow to the core and will accomplish the same thing as the two hose. I just prefer the dual hose valve for science reasons that I could make up if I had any facts behind them

Thanks for plugging my video guys!

 

I think both part numbers I gave you were for four hose connections to redirect the water back. I know the Ford one is for sure, that's the one I bought. Payton has a good how to install with pictures, look it up, very easy. He also tells you what vacuum line to tie-into for what you want.

 

Okay Folks Air conditioning is much colder, Thanks for all the suggestions. I changed the Fan, relay and blend door actuator plus added the valve to stop the water going into heater core, but I still dont think I am getting enough velocity from the fan passing through vents. If I shut one vent then of course it improves. Any other suggestions?

Is there a different fan motor that would be better? or fan blade change to force more air?

 

This may sound dumb but make sure you don't have anything blocking the intake. I remember my dad complaining for weeks of the same thing with an old silverado and it turned out to just be plastic grocery bag stuck in the intake.

 

Note: According to my Hanes manual (FWIW) Place a thermometer in the center vent, place fan on max, have a/c on but not on max. Rev engine to 1200 RPMs and hold. If you are seeing 30* below ambient or better a/c side of things is working great. < 30* ambient you have an a/c issue. On a 90* day I am getting 50* out of the vent, going down the road it gets a little cooler upper 40's.

 

not dumb, but that is one of the first things I did was to clean and check intake, previous owner had a dog. lots of dog hair in vehicle

 

I posted in the cabin air filter thread where to look for a cabin air filter. It would explain low fan output.

 

Definitely will be looking into installing the valve. Our truck has and odd habit, when cruising down the road with A/C on normal or Max it is cool but not super cold, but if you slow down like pulling into our neighborhood it gets real cold fast. All I can contribute it to would be less flow of coolant through the heater core when idling down. Thanks for the above info. Matt

 

Following post

 

Did you pull the fan motor or the fan motor resistor, to see if the evaporator has any blockage? All the air for the system has to flow thru there. I hope not, but if there was a lot of dog hair it might deeper in the hvac system.

 

Problem solved. AC evaporator full of dog hair. runs like a new one now.

 

WOW!!!


good to hear you got it taken care of!
