Hello, Had to replace my hose manifold for a leaking hi side port. replaced orifice ( blue). service with just over to cans. Calls for 1lb 9oz per label on truck.
doors open on max hi, 1500 rpm no fan or water on condenser, get 35/275 pressures and 50 at vents. With doors and windows closed get 30/250 48 at vents.
At idle max mode doors closed pressures drop to 20-30/225, cycles very minute or so and same vent temps, 95 ambient. Does this sound correct.
Also when driving 60 mph 50 at vents in max but slowing to 45 mph vents 45. seems to work better on hi recirc than on med recirc when rolling.
Last thing is when in normal vent temps rise around 5 degrees or so. Both inlet and outlet of evap seem about the same to touch.
Think I can get it better? Thanks Craig
Pressures look OK. Consider the possibility of reheating from the heater. You did evacuate before charging of course.
Thanks for the response. Yes I pumped it down for 30 minutes. Just curious about cycling at idle in max mode at 95 ambient and why it cools a little better at say 45 mph vs 60 mph, thinking pressures too low at faster speeds on the low side. Gets colder when on max hi vs max med when rolling, thinking more air flow raising low pressure or am i reading into this too much. Reheating you mean adding some heat? Pressures and vent temps are like a mystery to me with all the variables, just trying to get it straight in my head.
