Toyota Repair Problems? Ask a Mechanic for Answers ASAP
There are 2 fitting on the a/c system and they are different sizes. One is larger than the other and the tops of the caps are marked with a 'H' for the High pressure side and 'L' for the Low pressure side. You will want to recharge from the Low pressure side. The can you are using should also only fit the low side anyway.
I see the silver can with an H on the top valve, but there are no other valves that I can locate - so where is the low pressure side?
Here is the best pic the manual has..
It shows it along the passanger side fender area.
You can reach it from the top.
Have you read the instructions on the can yet?
Follow the metal line the is larger than the other one. It will run along the passanger side of the engine compartment and maybe in front of the radiator by the bumper.
No, it will look just like the high side. like these..
That pic does not look at all like the part I am looking at in my toyota sienna van engine. Am I correctly looking at a shiny can with one valve on top that has a grey cap marked H that I think must be the high pressure valve. But where is the low pressure valve - do you have any toyota pictures or drawings?
I have helped as much as I can without standing there with you. I will now opt out and see if another expert can help you find it.
As a note, if you are this inexperienced with auto repair, you may want to seek a professional repair shop as this type repair can lead to personal injury and damage the environment as well as violate EPA Laws.
Here is a great site to find a professional shop..
Genchi suggested that we find professional help, so we went to the neighborhood auto store and they helped us. I am afraid that Genchi gave us the wrong diagrams and photos for our car's air conditioning system, even though the book page looked as though it should be, but it was not. Therefore, we did not use the advice and it did not help us other than to go get help.
So we did not use the suggestions other than the one to seek elsewhere.
If the advice did not help us are we obligated to pay?
