Empty Engine Compartment ?

Andras Nagy · 06-02-2003, 03:55 AM

Thinking about lightening the engine compartment by removing the heater hoses, heater blower, A.C. radiator grill, etc. The car is a 1983 911SC.

Is there any reason not to remove the heater blower motor, the hoses, and all the A.C. equipment in the rear compartment? Any resultant damage or other bad thing likely to occur? The AC compresor is already out. I know I'll not have AC and heat, but at the moment they are not necessary, and it would seem that a nice "open" engine compartmet would make things easier to work on and to keep clean.

What should I do about the air coming off of the fan (once the hoses and the blower motor are gone), at the left of the fan, which goes into the heater blower? Should I blank that off, or allow it to blow into the compartment? Does that normally cool down the heat exchangers?

TIA...................Andras

Andras,

Do a search on "heater back date", this should tell you what you need to know.

Cheers

The heater blower doesn't make a difference, just extra weight. The opening on the left side of your cooling shroud needs to be closed, it's meant to provide airflow through the heat exchangers when on throttle so that you don't need the heater blower, but that's it. If you don't close it, it'll provide an unrestricted path to flow potential cooling air. As far as the AC, if it's going to totally come out, then the radiator looking thing mounted on the engine lid should come out, as well as the hoses and condesor (not totally sure what the one in the front is called) should come out.

Andras! Good to hear from you! I missed you and your gorgeous Rauschquartz Metallic beauty.

Since we last chatted here, I have removed my AC and backdated the heating. It's a great upgrade. Try to get the turbo left side air take-off, since your distributor is too fat for the plain, early take-off. Used parts can be had.

Yes, if you're not going to need AC, then remove it all. The hoses just pull out, no cutting needed. The radiator thing over the engine, and the one under the nose of the car, should also be removed. the stuff in the smugglers' box, too.

Again, nice to hear from you.

Brian and Superman,

Hi guys. Nice of you to remember me.

Much water has flowed under the bridge since last I was on the Board, but I still have the "rauchquartz metallic" 1983 SC, and she's still a beauty. It's like driving inside a Hershey's chocolate kiss - metallic chocolate on the outside, luxurious dark brown leather on the inside (including the headliner). Paule won't even hear of selling her; been a member of the family since she and I got her from Stuttgart (the 911, not Paule) in October 82.

At the moment, trying to simplify the car, and since I don't use the AC nor the heat very much, will be pulling all those things. And since my
theory of modifications is that one should still be able to revert to the original specs, I may keep the plumbing in place, and just pull the heavy stuff. They shoud be easy to replace, and don't have to rent a small storage room for the "long" stuff, like the piping, etc.

Anyway, all these posts have steered me in the right direction, and I will be pulling thinmgs off this coming weekend. With all the heating stuff gone, the engine compartment sure does look clean and "cool".

Cheers...........Andras

Wish I had a digital camera. It's fun to watch the faces of the tech inspec guys at AX when they open my hood. At first they don't say anything, they just stare. You're doing the right thing, Andras, although Fall may be a better time for an A/C-ectomy. It's going to be 90 degrees later this week and in Seattle, that's uncomfortably hot.

Your AC hoses are porous. This and their age makes them useless except the ends. The ends can be salvaged and placed on new (non-porous) hose. And the hose comes out surprizingly easy. So, there is little reason not to just remove it all. Like you, I wanted to have reinstall capability (not sure why), and I have that, even though all the parts are in boxes. The hoses are soft, so they can go into an ordinary (decent sized) box.

I know what you mean about the water under the bridge. I keep hoping for life to get simpler. Still hoping. Hoping.... Waiting......
