93 camry evaporator

Drake57 on Tue September 08, 2009 2:16 PM User is offline

Year: 1993
Make: Toy
Model: Camry
Engine Size: 2.2l
Refrigerant Type: r134a
Pressure Low: 50
Pressure High: 200
Country of Origin: United States

flushed condenser, could not force any flush through evap (though expansion block), charged w r134a, original compressor developed pressure, but no cooling whatsoever. I'm thinking flush the entire system including evaporator, replace compressor and exp block. Is the evap and expansion block a PITA to remove on this one? Has anyone r and r'd evap/exp block on this car and if so, what is the 50,000 foot rundown of it?

Thanks, Drake.

Do not flush through expansion devices unless you have a closed loop flushing system like the HECAT H1000. This evap is not that hard to pull out.

Yes you must have left a bunch of flush behind in the evaporator, now you will need to flush everything again to remove it.

If it's a block type TXV on the firewall, just remove it, then you can flush the evaporator in place.

If TXV is under the dash it should be like most Japanese cars of that era: disconnect lines under the hood, remove glove compartment, then working through the glove compartment opening, remove evaporator box (as a unit) from the car. Undo the clips and open up the box, now have access to evaporator and TXV.

Removing the blower motor housing makes the evap removal much easier.

The evap would not take any flush, or 100 psi nitrogen, I think exp block is fouled. I did not pry too far, but it looks like the evap is in the center console, seemed buried. I did remove glove compartment, saw blower housing just above glove box, I saw what I thought was high and low pressure lines bundled in some foam, dressing from the bulkhead at firewall to within the center console.

Thanks for the assistance.

Thanks very much guys. Is the evap mounted above the blower housing, more or less above the glove compartment, or is it mounted within the center, more or less below the radio?

Should be between the blower housing and the heater intake. As mentioned the evap comes out as an assembly, then the core or exp is removed.
