Taking the plunge. My journey as an O/O.

Tractor Supply had freon on sale last month for 36$ a case. I bought 2 since my van needs a new Schrader valve and semi isn't blowing cold ..

Ive had gauges and vacuum pump along with a Hanes A\c technical manual for years.

 

Is that an ECM setting? Will the shop cover the charges if you stop and get it turned back on?

 

Never got it that cheap. My Schrader valves leaked out on mine, now. Got to fix that. The Valve tool is a larger type. Can’t find mine. Auto parts stores shows having them, in stock. For some reason, I had a hard time finding the one I have.( That I cant find)

 

I meant expansion valve on the van. Getting some abnormal high pressure reading on the low side when I tried to put a can in the other day with cheap recharge hose.

My gauges are up north.

I’ve yet to see what’s going on with the semi other than it’s not blowing cold .

Put some gauges on it and see what they say. Probably tear the system down and flush and reseal it , maybe new hoses while I’m at it.

Internationals have a funky heat and a/c system being everything for the front and rear heat and a/c is in a box under the passenger seat than runs through a plenum through the floor.

I found a shirt stuffed in the box for the rear heat, I’m guessing they were trying to route more heat to the windshield defrosters .

Can’t imagine the air is very warm after it runs along the cold floor to the defrosters. Same with a/c.

I am going to have to insulate under the floor outside to make it efficient

Soooo much stuff that needs doing on this truck to make it Right.

Yea I already regret not buying 2 more cases of Freon. Tough to beat $3 a can

 

The good thing about the IHOP, is it’s pretty handy, to work on. Though the systems are a little different. Someone here can definately help, if needed.

 

Any authorized Detroit shop can do it if it’s as simple as an ECM setting.
