Anyway, some minor update.
Last CNY I experienced aircond feeling warm and the water temp increased slightly on my gauge, when sitting in a standstill traffic jam entering a parking lot for 15 minutes under the 1pm super hot sun, the temps fell immediately after I turned off the ac and then the traffic started moving and my aircond temperature started to improve, so from there I suspected I have an issue with my cooling fans. Went to install tints on my front windshield as I torn that out when I went to Puspakom, and still my aircond felt like it wasn't as cool as before.
After some looking around, this seems to be one of the possibilities, there is a large gap between the radiator and the body, where on the original radiator the gap is much smaller, I suspect the air might be recirculating, meaning instead of sucking in fresh cool air from outside, the radiator fan was pulling in hot air from the engine bay instead.
Did a quick mcgyver solution to fix that
And driving around these few days, my aircond seems to be cooler now when driving after parked under the hot sun and when in standstill traffic under the hot sun. Next step would be to replace my AVS pusher fan on the driver side to a SPAL fan and hope it solves my issue. Will also apply some foam surround between the radiator and condenser to make sure more air actually flows between the condenser/radiator instead of bypassing it through the sides. Will update again when i find the time to do those....
