Vintage Air install
 

Good morning.

On the 72 K10 im building i am at the point of installing the Vintage Air system i just purchased. I have a few questions im hoping someone can clear something up for me.

1. - Can i keep the same setup for the vintage air in regards to the fan clutch (new one) and the radiator shroud or do i have to purchase an electric fan kit?

2. if i need to purchase a new radiator and electric fan, what brand(s) did you use? (Radiator brand, and electric fan brand) i see some have used flex a lite fans.

some of this stuff can get pretty pricey and im not opposed to that but dont want to waste $$ either.

No need to replace anything. The system will work just fine without electric fans.

Same here. I installed mine last year and did not touch the cooling system. no issues at all. The only thing I would recommend is to install some sort of "idle kicker" to bump up the revs when the compressor engages. Mine keeps blowing cold at idle even without the kicker.

If the truck runs cool now I wouldn't worry about it. If it can sit in hot traffic and stay cool you should be fine. If it doesn't then you may need the extra cooling fan.
There are 2 things to remember about cooling.
#1 is the water temp needs to stay cool.
#2 the ac freon pressures have to stay low so the tempature does to!
Most clutch fans will do the job of both but if you have a thick 4 core radiator and a massive condenser then the clutch fan may not do the job. It has to pull enough air through them to keep them both cool to work properly.
The more you seal off around the radiator support and force the air through the radiator and condenser the better the cooling.
Another suggestion make sure the hot water valve is in place and working. It will drop the cab tempature by 5-10 degrees. :chevy:

Error I made. The solenoid valve that controls the heat is directional. I called VA because my heat would sometimes work for a short while and then just stop - fan runs but no heat. Va said I had valve in backwards - changed and no more problems.

THANK YOU EVERYONE FOR YOUR ADVISE. i just see such exravagant cooling setups and i thought i would have to do so as well. So i dont have to worry about the binary / trinary switch hook up? I assumed that was for the electric fan set up only?

Re: Vintage Air install
 

That switch is a combo switch to turn the electric fan are fans on if needed to keep the pressure down inside the AC system. It also shuts the compressor off if it gets to high.:chevy:
