Thread: A/C not working in traffic/extreme heat!

I honestly don't think the heat in the engine bay has much if anything to do with your system's ability to blow cold. It can effect the system slightly, but that's why there's a condenser fan, in addition to a radiator fan. The condenser fan isn't to cool the coolant in your radiator, but to assist in cooling the condenser coil.

If you look in SOME auto manufacturer's cars, the condenser coil has it's own dedicated fan, that isn't shared with the radiator.

A lot of times I see people say that when you recharge the system, you should check with an I/R thermometer for around 35~40 degrees (F) of output. This should only be assumed at 80 degrees (F) (with low relative humidity) outside temperatures. If it's 100 degrees (F) and roughly 50% humidity, you should only expect output temperatures at idle to be around 60~70 degrees (F) when checked with an I/R thermometer.

I'm no guru with A/C though, so I could be completely off. This is just what I have learned over the years when repairing my own A/C systems in cars.

Well I made arrangements for the above to be done today, hoping its done whilst the sun is hot so I can give you all an update.


Thanks for the awesome advice and inputs... Much props my sr20-forum

Hope it works out for you!

this is false

incorrect

give this man a cigar....this is true

^My thread.

^Here is my parts list. I did not take one shortcut.

what usually causes the traffic heat is the idle when the car is not moving need to be at 900 rpm nand thats the least...1k works for me. u need to install another fan for the condenser as the two may not be efficient enough for the car now.... must ppl forget that the condenser should be washed as well as the fins in the cond. and radiator may be bent thus stop proper heat exchange. a clean evap is key but as u have in ur list that u got a new one so i would assume u serviced the filters and reinstalled them.

Oh, really? How so?



First of all, please use punctuation. It was difficult to read (not picking on you, only asking). Secondly, your statement with regards to the 900rpm base idle is for what vehicle?

Last I had checked, any vehicle with manufacturer's specs does not idle above 900rpm, warm; yet their A/C systems seem to work fine when properly serviced...
