Model: Previa
Engine Size: 2.4
Refrigerant Type: R134A

Hi , i worked on a UK Toyota 2.4 Previa with single AC system yesterday and found the minor leaks at last . The first leaks are from the two short metal pipes from the TXV to the main feed pipes / mounting bracket. The other leak is from the HP Compressor discharge hose to condenser. The first part of the hose is aluminium and has some minor pin holes in them.

I was looking for a exploaded view to enable me to find part numbers etc so i can confirm what parts i need before i call the dealer. I expect that these are main dealer parts only ?


It looks like these have corroded from the outside in and wonder if this is a common fault with toyotas and also other makes. I had to put dye in the system and then with a UV lamp was able to find the very small green dots where the leaks are.

Thank you for your help in advance.

OE exploded view and part number information is available for a fee from the OE, Mitchell, Alldata, etc. It violates copyrights to freely share said info. Some will offer a very minimal fee for one day access to get the info you need.
