You are watching: Jeep grand cherokee low pressure ac port


Hi all, i bought a coolant recharge deserve to to beef up mine AC this summer. I watched the video clip but my engine doesn"t have the AC harbor in the very same place. I found this harbor behind the engine, but I"m not sure if it"s the short or high port. If anyone has actually done this or can suggest me in the direction of an engine diagram, I"d be thankful. Have actually a great Sunday.

if its working dont do anything.adding refrigerant no "beef" something up.Also I believe your jeep bring away 1234-yf refrigerant.If its not working good (you can test with a thermometer in the vent)take it come a pro.

Rand said, take it come a pro shop. The modern systems can be very finicky come both too much and too small charges.

!00% agree v the others, AC has constantly been finicky and its gained worse/more touchy through the new type of refrigerant so without the proper collection of AC gauges and also the knowledge and also specs the whats claimed to be in the mechanism you basically have actually less than a 1 in 1000 possibility of including the correct amount through a walmart recharge can. Simply let a skilled do it. That might already be full, the brand-new 1234-yf ingredient doesn"t really work the greatest even when the cars room brand new.

Talking with someone that knows more than ns do around A/C a when back, I obtained that more recent refrigerants favor 1234-yf require greater system push to supply the very same performance together older (ozone great killer) formulas. Greater pressure method more difficult to handle, much less margin for error. Oh and an ext dangerous, especially on bigger systems.I would certainly not touch mine... If it"s no blowing cold air >> obtain a pro to work on it.

Certified A/C tech and body guy here. The port behind her engine is the low pressure port. The high press port is under the black color plastic cover the goes end the top of your radiator. The problem, as others have actually stated, is the your vehicle uses the new R-1234yf coolant, i m sorry is no compatible with the enlarge R-134A. So do not put a booster can of R-134A in it. Castle use different chemical compositions and also operating pressures, and can damage your compressor. And also as was also mentioned, the lot (and thus operating pressure) the coolant in a modern-day system is really precise. Too much or too little will dramatically impact system efficiency. Additionally, as brand-new as your auto is, if the system has actually lost enough coolant to call for a recharge, you have actually a leak that needs to it is in fixed. Contemporary cars carry out not naturally lose Freon fast sufficient to call for a top off ~ a couple years. In fact, most newer vehicles will certainly never require a recharge unless they build a leak.
