Items mounted in front of car near battery

[myslateblue911]

I think my battery in my 1983 SC 911 finally gave up the ghost. When I got in there to take it out in the frunk it was a very tight spot. There were two items to the left of the battery that I had to remove to get the battery out. One almost looks like a fan or a horn. And the other is like small little plastic container with translucent tubes that go into it. Not sure what either one of these items are. Any help on identifying them would be much appreciated. Thank you.

Windshield fluid pump.

i think the ac condenser fan is there just in front and left of the battery but you shouldn't have to remove it or anything else factory installed to remove the battery.

But please, with whipped cream and a cherry on top, post a picture of what the heck you are referring to.

Yea, it sounds like the AC condenser fan. On my 85 it is a super tight fit for get that big ol battery in or out. Removing the fan is pretty easy with four screws and the electrical connector. It is an excellent time to double check that there is a fuse on that fan as the factory did not fuse it, and it burned down a few cars.

I usually pull the fan and the R&R the battery. Depending on your last battery installation, it may well have a drain tube for battery acid connected as well.

I recently replaced mine with the AGM (glass mat) battery that is identical to what I put in my wife's 2017 Macan. On the Macan I had to program the serial number and part number, and amperage into the car's computer. The 911 of course needs no computer to program it.

@myslateblue911 -- consider replacing your current (H8/Group49?) battery with a H6/Group 48 AGM-type battery. It's slightly shorter than stock, which makes it easier to fit into position (I didn't need to touch AC fan or washer motor) and our cars came from the factory with a second mounting point on the battery box to snug down this battery size. I'm on my 2d H6 AGM battery (first lasted over 8 years) and have no issues starting car in cold/running AC, etc.

Yep - a/c condenser fan and windshield washer pump. I place a towel between battery and gas tank when removing/installing the battery. Otherwise, you can scratch off the tank’s coating given the size and weight of the battery and the tight fit.

Because you asked with whipped cream and a cherry on top

917's just having some fun at your expense

I'm darn sure Porsche designed the battery to be removed with the other parts in situ. Lift and tilt. And clean out that rust while you are it !

It's been said on other threads so let me say it again here: The 911's up through about 1989 don't need nearly as big a battery as they came with. I've jumped my car from a motorcycle. I would look for a much smaller battery to put back in, both to reduce weight, and to improve serviceability. In my 1973, I have only one battery in the right front battery box, and it's a small battery so that it fits in that box. I'm cranking a 3.2 motor, and it will crank for many seconds before it starts to slow down.

I know, it's all good. I did actually look through the service manual for some kind of diagram identifying everything in the "frunk" but could not find anything. So I headed on over to this wonderful brain trust of Porsche air cooled knowledge.

Thanks for this. Do you know if there is a diagram of everything in the "frunk"? If so, what page?

Now, that would be way too useful to be produced by Porsche. Instead, they organized the PET by major and sub groups, which is also useful, but not necessarily easily searched through. Ctrl F is your best friend here, but with the caveat that you need to be able to speak Porsche; what you think it is is not necessarily what Porsche called it! Yikes.

It would be nice if there was a pic of the trunk with details of what is what, but the best I can do for the specific items you listed is to note that they are located here:

Front condenser fan assy: MG 8: SG 13: Illustration 813-45 (p. 431)

Windscreen washer system: MG 9: SG 04: Illustration 904-10 (p.465)

The most important bit to the PET is not so much identifying the common name for these items, but how they were referred to by Porsche, which is not always intuitive (already covered, but I wrote this bit first), and by part number, which is far more likely to score a google hit than the odd name Porsche lists the part.

BTW, it is possible to remove the Group 49 batt. but it definitely is a challenge.

FYI, I removed the fan duct from the front bulkhead once and it was a major PITA to get it back in. All sorts of soap and swear words were used will little luck. I eventually got it back in, but it was a major fight.

If you remove the washer pump from the rubber mounts, dont pull the rubber nubs out or you'll have to take the front bumper off to pull them back through. That's what I had to do, but I was rehabing all that stuff in there anyway, so it worked out.

That Bentley looks way too nice.
