I've successfully converted two vehicles from R1234yf to R134a. A 2015 Ram 1500 and a 2021 Honda Accord which are both working fine. I purchased R1234yf quick couplers that allowed me to use my R134a manifold gauge set, vacuum pump and other tools that I already had. It's very important to completely evacuate the system of all R1234yf, you do not want to mix them.
Simple Question: the cap on expansion tank goes on by pushing down, then a quarter turn will secure it in place but it wiggles a bit on top, then push down and another quarter turn locks it down. It stays on both ways. It doesn't just screw on like a threaded part. So which one is correct? One quarter turn with a jiggle or two turns and no jiggle? Thanks
Boa noite sr engenheiro tive um problema estava com a maquina a fazer coding e nao reparei a minha filha puxou o cabo logo ao princípio quando estava a fazer coding com autel entao me gerou uns codigos de erros seguites 27A800,CD8486,CED400,E71442 tornei a fazer o coding desde o princípio novamente depois analisei os erros sairam todos so que estou a ter um comportamento estranho no carro quando acelero e largo acelerador torno acelarar ele parece que falha a potencia ou ate parece que trava durante 1 segundo podera ter causado algo tanto andei que acabei por programar e codificar e atualizacao software levei a centralina para o programador meter a reprogramacao mas o carro continua a fazer o mesmo e nao me da codigos de erros sera que foi algo no modulo FEM ?
In my situation, the fix was to spray the electrical connector with electrical cleaner. Be sure to disconnect the battery negative terminal before spraying and wait for it to dry before you reconnect.
Holy shit. I've replaced the radiator, the thermostat, the water pump, cleaned out my heater core and all I needed was this damn overlooked radcap. Thank you sir
The modern engineers way of thinking ... We will make it more difficult , complex , and most important , More expensive .. Yeah , i can just see them high 5ing each other ..happy they figured another way to fuck the consumer .. Big bonus in there pay this year for coming up with this one . Makes me sick ..

Any harmful ,damages to the AC system if we retrofit system from R1234YF to 134a !!! If it does what parts and why it got damaged !??? Good question Right !???
If the signal voltage is high,the fuel rail pressure is high What's the solution??? If the signal voltage is low ,the fuel rail pressure is low What's the solution??
No. Valvoline is mediocre in the viscosity I use. In the viscosity for your vehicle in synthetic it's great. But in the base it's ok for maybe 3000 miles but I wouldn't run it longer. I do not need someone's advice that doesn't know what I know.
