You are watching: 1999 chevy suburban expansion valve location
Where is it located? normally in the trucks w/o front/rear a/c that in the condenser, however I have heard they room in the line close to firewall top top Subs with front/rear air. Anyone know for sure?Im wanting to change it v a vov type.
It"s situated in the Y that is atatched come the passenger next inner fenderwell, yet don"t waste her time as your A/C will certainly SUCK afterwards if you placed one in. Ns tried this and also it do teh A/C work an excellent at one idle, however it blew just mediocre at speed as the variable orifice will certainly not function properly v the rear expansion valve, and also they even tell you to no run them in a dual system v a rear expansion valve. I finished up placing an electric fan on mine condenser to do teh A/C work an excellent at one idle.
Thanks for the heads up. Thats all I should hear then. If you did"int choose the results then i won"t waste the moment repeting the same thing.Whats wierd despite is the male at the a/c shop stated it would work better at idle and also the same as prior to at speed and that the evap valve and vov would compliment each other.My a/c male has been in the service over 35 years and also is an extremely knowlegable.My old 94 truck with single cab air and vov would certainly freeze you the end of over there in July. It was so nice!
They work an excellent in a single app, or also with a behind orifice. Ading the electrical fan come the condenser made much more of a differrence 보다 teh VOV go anyways, plus currently it is COLD going down the road.
I was going to add a pan also. Hooked to "run" strength so there is no delay in a/c cooling at idle or in traffic on warm days.Since the engine oil cooler went away with the Isuzu swap (Isuzu is a water to oil cooler in the block) that gives me a perfect clues to add the fan. ~ above the 454 gassers you can get a manufacturing facility pusher fan its a bolt in deal. Ns ran 2 of castle on a Cummins conversion.
There is a "severe duty" orifice tube easily accessible that we usage in every our conversions. Any good a/c shop should understand what I"m talk about. That is a change orifice tube for low rpm/extremely warm climate situations. Expensive, however is the finest I found.works in the vans w/rear air. Never ever tried in a suburban tho, so ns can"t vouch because that that.

I simply went v what ns had. Choose up aux cooling fan today. It does not seem to blow together cold together before. Press on gauges never got to the readings I typically see. How plenty of ounces or 134 does the double air burb take? follow to AZ that 63oz so thats what I put in. The high side only acquired to 170 and low stayed up roughly 70. Ya"ll think i need much more 134?
What compressor space you using? sounds to me from your press readings that it"s not moving the volume necessary for a twin air unit. One of two people you have actually an orifice the is ruptured and bypassing, or the development valve because that the rear is hung open. Through the high next being low, and the low side being high is a dead indicator of this. And the fee is right roughly 4 pounds, therefore 63 ounces is fine.
