removing A/C evaporator

Postby qikteg » July 8th, 2013, 1:02 am

I've removed all the AC gear from the firewall forward (compressor, plumbing, core etc) and have sealed off the two pipes that feed through the firewall into the evaporator.

In an attempt to entirely remove the AC system, i'm thinking about removing the evaporator from under the dash entirely.

Question: will removing the evaporator entirely affect the heating/fresh air/fan systems at all? in looking at the service manual, it would appear that the evaporator is directly connected to the blower motor, but i can't tell whether it only draws out of that space when the AC is on?

relatively, I know there's no gains to be had by removing the evaporator, but i just figure that if i can remove it without affecting any other systems, i should.

Cheers

Leave it in place if you intend to use the heat. If you remove it you will need to connect a conduit between the blower and heater core if you want to have heat.
If removing for weight you only save about three pounds.

Curious to know if the blower motor is still located on the right side of the teg as the glove box would have to be on the left in your case. Regardless, we can grab the plastic crossover tube for you if you go that route.

I think it's on the left side behind the glove box... At least that's where the high and low pressure pipes stick out from in the engine bay.

I'll have a look over the weekend to see whether it's worth it. Because I need to get the car re registered, I'm concerned about how anal the inspection might be ie. If it is seen that it has an evaporator, then where is the rest of the aircon system? where's if I remove all traces of there ever being ac, they may assume that's how it was from factory...?

Oh wow! They really swapped the dash around then. Need to take better pics of the underhood valances. Since our blower is on the right side, that piece of plastic is blank. All the inlets are on the passenger side (left) for USDM. Be pretty cool to get reverse valances EDM/ADM for the engine bay and have air drop straight into the blower. 8-) Your inspectors are pretty anal sometimes. Wouldn't bother anyone here to remove the AC. :D

i'll take some pictures over the weekend so you can see how it differs. if it all lines up, i wouldn't mind trying to get the USDM blanking plate that you guys have to clean up the engine bay - i'm sure that i could find a rubber bung or rig something up, but nothing beats factory fitment. I figure though that i could potentially use the existing holes to feed through some low gauge cabling when i do the stereo - eventually.

haha yeah, the level of scrutiny can be pretty intense... obviously it all comes down to the inspector as to how lenient or observant they are, but i know of a few people who have had nothing but headaches when it comes to getting a car back onto the system. maybe i'm just being paranoid.

but hey, 3 pounds worth of evporator means that i don't need to lose 3 pounds to get the same power to weight gains... nice...!

The blower motor is on the right side of the dash, the AC equipped car will have a hole in the box that the evaporator lines went through, it will need to be sealed with something. I used that aluminum looking ducting tape used for HVAC. There is an option to replace that box with the vent tube from a non AC equpped car. Its a cleaner conversion but not necessary.
