i have opened all 5 doors and fan was also on full swing while charging gas and measuring vent out temp , the head pressure was looking quite normal , 35 and 155 psi on 1500 RPM and the amient temp was 28 DC ,,,,,,,,,,but there is a problem in it ,,,,,,,,, acording to the ambient temp (28 DC) the low and high side pressure must be around 40-50 and 175-210 psi ,,,,,,,,,,i guess i have low charge the system , there was no refregrant weight tag on any place on the system and on the under side of car bonnet ,,,,,,,,,,,,but i have seen a tag on my 07 cultus which is fitted with sanden system from paksuzuki and also with multiflow condencer , that system is still running with original gas which is filled by paksuzuki ,,,,,,,,,,,acording to that i have to fill 450gm refregrant,,,,,,,,,,the refregrant cans which i buy was of i guess original japanese KELA 250 gm,,,,,,,,,so it means i need atleast 2 of those cans ,,,,,,,,,,,,,,but in real i have charges 3 cans ,,,,,,,,,,,,but still i wont get the desired reading on low and high side,,,,,,,,,,,,,,,i dont see any fault in comp ,,,,,,,,,,,because it has suck all the refregrant out from the last cane,,,,,,,,,,,,at that time system is working very perfectelly ,,,,,today my brother has used that at day time and he was said its chilling ,,,,,,,,,,i never experence such performace from any suzuki car (as per his knowlede),,,,,,,,,,also the comp wont put any load on engine , , that amazing ,,,,,,,,,,,
i see 2 reasons of that,,,,,,,,,,,first of all the 450gm quantity was of sanden/multi flow conderncer system,,,,,,,,may be the old style ND system need more weight,,,,,,,,,,,second thing,,,,,,,,,,,,the cans was not of full weight ,,,,,,,,,,,,,,almost half,,,,,,,,,,,i can feel that the cans are almost half as you know the gas in them is in liquid form , also its weight wont seems 250gm,,,,,,,,,,,,as you know gas escapes from the cans and i have experenced this thing in another cane which is stored in my home store for last atleast 2 years ,,,,,,,,,,,there was hardelly 50 gm left in it out of 500 gm ,,,,,,,,,,,,,,,,any how i will gave a second test that system ,,,,,,,,,,my 07 cultus is also running with low refregrant so i have to add some refregrant in it as well ,,,,,,,,,,,,,,will add some more refregrant in this car while adding in 07 cultus ,,,,,,,,,,,,,,,as per my knowledge its common that new and untouched cars lose some refregrant with the passage of time ,,,,,,,,,,so 07 to 12 ,,,,,,means its the 5th year of that car and i am sure almost half of the refregrant is lost in all that time,,,,,,,,,,,,,,and i guess its not any fault,,,,,,,,what you say about that ?
