bazmlb Posted November 16, 2014 Share Posted November 16, 2014 Well after the AC not working and the Mechanic giving a quote of 5,000 baht for a second hand compressor after trying to charge the car with Gas without it running. A brand new Sanden SD 507 can be sourced for around 2,500 baht, so They were making a heap on their quote. All the hoses were shot as well after I pulled it apart, outer shell perished from heat and age, the inner then goes and they start to leak gas, which can create a wet spot on the hose from the lubrication oil from the system leaking with the gas. The Condensor and evaportator are in Good condition. The Receiver dryer looks a million years old, yet a 134a model, so will chage it as well, Local mechanics fail to regularily do this, its like a car engines oil filter and removes impurities and moisture from the system and is a serviceable item, not to be left for ever. The TX valve is an unknown in the car, was never very cold, so a new TX will be going in while its all in pieces as well as its getting converted to 134a from R12. The Receiver dryer High Pressure hose to the Evaportator The Suction hose to the Compressor from Evaporator The Sanden SD 507 that will be replaced with larger SD 508 TX Valve Internal housing with Fan, TX Valve and Evaportor, as you can see there is a lot of dust built up on the Evaporator, this can lead to mould growth and smell from the AC unit, it also reduces cooiling, same with the fan, the blades like a pedestal fan build up with dust and reduce in efficiency, cleaning of the unit at least every 5 years is reccomended for health and performance. More to come as it goes back together. Link to comment Share on other sites More sharing options...
alanrchase Posted November 17, 2014 Share Posted November 17, 2014 I could not believe there is no filter on my Toyota Tiger A/C, gets clogged up every 5 years or so. Link to comment Share on other sites More sharing options...
uwe_rayong Posted November 17, 2014 Share Posted November 17, 2014 TA by screen do you mean the cabin air filter below the glove department? Link to comment Share on other sites More sharing options...
CapeThai Posted November 17, 2014 Share Posted November 17, 2014 Best to have the system properly service ( vacuumed and new compressor oil with the correct amount of gas - not over gassed ) with a Piccola Evo machine or similar after all O-Rings is replaced with the green one's and everything is put back together. Just adding gas " top-up " to a vehicles aircon system is asking for problems which will cost you dearly at the end I will be expanding my business ( Automotive Aircon Servicing & Automotive Electronic Engineering ) to Thailand in mid 2015 should anyone need assistance.

uwe_rayong Posted November 17, 2014 Share Posted November 17, 2014 (edited) Yes TA I also clean that from time to time, as it gets quite dusty. But I never changed the dryer filter which Bazmlb mentioned, I googled that and it is indeed recommended to exchange it after x? years. It keeps the system dry and clean and prevent damage of the AC from the inside. My AC is still running cold after 7 years, never refilled or cleaned it, but if it is very wet outside i.e. strong rain - sometimes I have some foggy air from AC for a few seconds. So maybe I should change : ? How much is the "receiver dryer" on a Toyota Vigo? Edited November 17, 2014 by uwe_rayong Link to comment Share on other sites More sharing options...

The Vacuuming removes any moisture left in the system and is a must for a good performing system, the HNBR nitrile orings (green ones) are used for HFC134a gas as the black ones do not cope with the gas or its higher pressures. The system should also be flushed if changing from R12 to HFC134a if an old car, receiver dryer changed, compressor rebuilt with new seals and the rubber hoses replaced as hfc134a does have a higher head pressure, now you may not know what gas was in the car it could have even been LPG as it has similar characteristics as R12, although can cause car fires on a leak.

bazmlb Posted November 17, 2014 Author Share Posted November 17, 2014 How much is the "receiver dryer" on a Toyota Vigo? Normally around 400 baht, pls vacuum the system, plus gas The results pf not changing them could possibly be a blocked TX valve, which could blow the compressor from lack of lubricant flow or a blown compressor from contaminents both a lot more expensive than option 1 I gather the later models dont put one to save money as car life expectancies get shorter Link to comment Share on other sites More sharing options...
bazmlb Posted November 17, 2014 Author Share Posted November 17, 2014 I could not believe there is no filter on my Toyota Tiger A/C, gets clogged up every 5 years or so. The next generation does, the Vigo, can't really call it a filter though, more a screen. I believe the Triton doesn't, unless they now fit one on later models. Don't get the evaporator air inlet pre screen mixed up with the receiver dryer, ones cleans the air we breath in the car, the later clean the gas in the AC system Link to comment Share on other sites More sharing options...
janpharma Posted November 17, 2014 Share Posted November 17, 2014 When I took my Pajero for a service the shop (Mitsubishi Dealer) asked me if they could "clean" the aircon...this was in Klaeng. They would charge 2000 THB for the cleaning only + the cost for changing the filter....!!!! Link to comment Share on other sites More sharing options...

And they probably just changed the Air Filter for the in car air, most people in Thailand use Recirc, so they dont get that dirty. The process when ac is on fresh air supply The filter that cleans up the air (not so easy to change on some cars like an E36 BMW Link to comment Share on other sites More sharing options...
bazmlb Posted November 17, 2014 Author Share Posted November 17, 2014 Here is what the receiver dryer does, it also acts as a suction accumulator where gas turns back into liquid in the compressor off cycle so it doesnt build up in the compressor suction port and hyfrallic the compressor to death, the first 50 seconds of on cycle turn the liquid back to gas and this is why little cooling takes place in this time.

Hi Transam I got steamy windows the other evening, the night of the heavy rainstorm, it seemed the air was not cold and therefore not dry. Yesterday it was working.....but I thought Be Prepared. I generally use ProAuto for stuff now and very pleased, but should I use a specialist for air checkup/fill? Could be the pressure only enough to intermittently engage the switch for the compressor clutch......could be anything of course. I've read your BQuik down past Hang Dong charge 500 baht for a refill on a small car.....seems cheap to me if they check the hi and lo side pressure etc......and guaranteed you say?.......can I consider them a specialist?
