Is this just tee's in the cooling and refrigeration systems?

 

Big Daddy, Do a search on this. I remember ready some good detailed forum post on this just a while back.

 

I'm watching a YouTube video on a guy installing an aftermarket A/C and heat unit. I'm not clear on what this option provides on the van. Just tees?

 

Uninstalled tees for the heater hoses and installed/capped tees for the A/C. If the guy in the video was doing that on a camper conversion, the real question is why? That only makes sense for uninsulated passenger shuttle vans that are running all the time. Insulated camper vans normally only need supplemental heat and cooling when parked with the engine off.

 

I'm just curious as to what the option provides. I understand it's only useful heat/cooling with engine running.

 

Yes. The "package" is a little plastic bag with 2 Tees and a few hose clamps.
Most people who use them, use them to run hoses to an engine coolant water heater.

 

That's it eh?? lol

I'm assuming the provision for the rear A/C is already there.

 

This is it.
(can't find one of the Tees at the moment).

 

Thanks

 

I've heard folks say there's Tees for the AC lines. I just looked and didn't see any in the engine bay. They must be somewhere under the van or not very accessible.
I won't be doing a rear aux AC and I'm tapping into the heater hoses for a small water heater fora shower.
I'll be insulated pretty well, have white reflective roof paint and a vent fan. I think the dash heat/AC will be good in my case.

 

IIRC from Havis pdf, the refrigerant tees are between the engine and the passenger side frame.
