Re: Toyota Hilux

When you lose cooling, are the aux fans working? Is the compressor clutch engaged?

Re: CONDENSER question.....different sizes

Let's remember the purpose of a condenser is to reject the heat in the refrigerant. Some condensers are micro tubed, some are parallel flow, some are tube and fin. It not only is the size, it is the type that separated one from the other. Older systems contained more refrigerant than newer systems h...

Re: 2006 Saturn Vue low on freon but can't put much in

Recover the charge and recharge with proper amount. That way you can eliminate refrigerant charge as a problem. Most AC problems are low refrigerant problems. You could have a stuck control valve in the compressor. Easier to eliminate charge as a troubleshooting step.

Re: Recovery vs. reading the gauges?

The short answer is...yes and no. An experienced tech can usually get it close but the BEST thing to do is recover and recharge by weight. That way, one can rule out the refrigerant charge as a problem. The most common problem is refrigerant charge. If you had a cycling clutch system that used an ac...

Re: Ac accumulator/drier replacement

Is it leaking or low on refrigerant now? You want the system to be leak proof before adding a new drier. If it does not leak now, recover the charge and change the drier. Vacuum the system down and add your refrigerant.

Re: NOISES AFTER REPLACING AIR CONDITIONING SYSTEM

Can you state what parts were replaced? Back then, Fords had bad cycling switches, compressors, and I think they had blend door problems. The noise you hear may be the system equalizing. If possible, check and see if the center hub of the compressor is turning when it is blowing hot air.

Re: Evaporator size

Are you planning to use 2 evaporators? You will then need a separate metering device like they do for rear evaporators in a vehicle. It might help if you describe your vehicle as in make, model, and year. Also, what compressor are you using? do you plan to use a different condenser? A compressor can...
