Complete a/c heater delete?

Does anyone have a detailed diy on how to delete the entire a/c and heating system? (For track use)
Thanks.

I wouldn't mind hearing about how you did it, any gotchas, etc. Will it throw any codes?

thanks!

Well I already had the dash and everything else stripped out which made it easy to follow all the lines etc but I checked up on real oem to get an idea of where everything connected to the system. I got an a/c guy to come out and de-gas the a/c and then I pulled the belts and started undoing everything associated with it, it was quite simple now that I've actually done it, car will hopefully be started today so I'll let you know it throws codes etc

Did you disconnect the heater hoses and heater pipe that connect to the engine under the intake?

Yeah I done the heater side first while I was waiting to get a A/C guy out, I flushed the coolant and cut the hose coming from the back of the block with just enough hose left to put a plug in it with a hose clamp and I done the same for the hose running into the bottom of the expansion tank.

Are you leaving the dash out? It's really nice to have a simple blower for air on a hot track day I bet. Full helmet, and other gear depending on class.

Cheaper then a cool shirt.

Ah I see haha
Nah I'm not as worried about the heat, aslong as I have good ventilation! It's also a drift project so it won't see any street driving at all and on the track it will be in short intervals anyway. Worst case scenario I'll buy a mini fan and mount it somewhere

And nah BKMrsteel I'm sticking with the dash and also the front door cards haha, I'm trying to keep the interior as clean as possible even though she's gutted

Btw just an update: I managed to finish off my wiring so I could finally start the car back up! Everything is a-ok and no codes were thrown whatso ever!

Nope, that's not it. That's why I wanted YOU to take a stab at this....

My Ride: needs more HP
So Rob... I know exactly why your saying don't remove the blower fan, but on the E46 it comes out as one big housing with the heater core, evaporator and flaps, etc, and it's NOT light. I'd have to take a look and see if there is a practical way to remove and remount it, or gut & cut the housing... but may not be worth the hassle. Considering making weight is a factor for some, defroster strips might be easier.... Or just use Rain-X Anti-Fog?

Bingo Bingo, winner winner chicken dinner !

***********************************

Having the ability to defrost the front windshield is paramount in certain situations. I can't & won't speak to all the continents of our world, but here in the USA there are many weather situations where a working widow defroster comes in very handy at removing condensation. For me it's a must have item.

Ah I see haha, yeah that came across my mind but I'll just keep the windows down when I chuck it on the trailer, it's basically hot all year round in aus so I'm not really worried at all.
If it becomes a problem I can address it once it happens
