Does anyone know how to remove the heater core?

Also to remove the gas tank on a 1987 924s do you really ave to remove the transaxle and rear window(as stated by the haynes manual) to get it out?

Thanks

heater core is sandwiched inside the blower box, you want to follow the manual, but heres some cliff notes.. disconnect heater hoses at back of the head in the engine compartment (dont break the valve) , remove blower motor cover. pull dash, console, etc.. remover blower box(four screws under where the blower motor screen was in the engine area), separate, r&r heater core.. assembly is the reverse of installation..

schedule at least two days.. take allot pictures, mark all wires and cables before starting, dont force anything.

as for the gas tank, yes you have to pull the transaxle...i dont see a reason to pull the glass hatch, but thats the easy part....

I have gotten off the hosing and blower motor and can see the core itself. I tried to take apart the dash but got stuck by what appears to almost be rivets? How do i remove these, are they actually rivets or just something that snaps in?

Thanks

mounting tabs are riveted in, follow them and youll find screws...

If you bought the Porsche 944 Factory Service Manual like I advised you to weeks ago, you would not be asking these questions.

I warned you that the Haynes Manuals were useless.

Why would you destroy the dashboard and heater box to remove the heater core? You certainly aren't going to save much weight or get much money for the heater core after you remove it.

Or, is this like your idea of stripping the engine block (removing the waterpump from the engine block) and selling parts separately (the result of an inexperienced and uneducated mind)?

ok first off thank you for your uselessness.

Yeah right weight...thats why i would remove a heater. Your an idiot.

In order to heat an electric car you either need to pump something though the existing heater core OR remove it and replace it with one that runs on electricity.

i would have never said remove the water pump had i realized it was much more built into the engine than just run of the typical serpintine belt and since it was i was never going to either.

now if you have any help that would be great if not, go away and stop pretending like your know everything the only thing it helps is make you look like an ass.

Beware the wrath of Gohim!

He speaks the truth. You asked for advice, he gave you good advice, and you refused to follow it. How does that make him useless??? Frankly, it makes YOU look like the idiot.

Anyway, if you have a Haynes manual (errors notwithstanding), it VERY CLEARLY indicates how to remove the dashboard. You do not have to remove any rivets to get it out.

Are you keeping the AC system in the car? If not, you can remove the heater core without having to remove the dash by first removing the AC plenum and assembly under the passenger foot well. I've actually removed and replaced the heater core without removing the dash or the AC, but that was before I knew better. I wouldn't advise it. The dash is not difficult at all to remove, and once it's out, it gives you great opportunity to address all of the electrics while it's out of the way.

Sorry, forgot the second part of your question.

There is no need to remove the hatch in order to remove the fuel tank. I can't begin to imagine why Haynes would indicate it as necessary. However, it is very easy to do.

To remove the fuel tank, you MUST remove the transaxle and halfshafts, as well as the exhaust (from the cat back).

The waterpump on MANY MORE MODERN ENGINE DESIGNS is driven by the timing belt (including VWs, and Toyotas). Knowledgable, and experienced mechanics do not attempt to teardown engines, with getting the manual and studying it to avoid damaging components and to AVOID INJURY.

The Haynes Manual 944 says to remove the left rear window (NOT THE REAR HATCH GLASS), before removing the trim panel. The reason is because the top edge of the trim panel is wrapped over the 1/4 window bottom weatherstrip flange.

But that's a mistake ! ! ! The RIGHT SIDE 1/4" trim panel needs to be removed to access the gas and vapor lines (fittings are welded to the inside of the 1/4 panel to support different vapor recovery hose schemes from year to year, and the 1/4 panels themselves are different from year to year). The Haynes Manual says to REMOVE THE LEFT TRIM PANEL (wrong side).

This is a typical Haynes Manual Mistake.

AGAIN, get the Porsche Factory Workshop Manual and avoid this type of mistake.

I think the easiest way to remove the heater core if you dont need it again is to just take a hole saw to it and then pull out all the pieces.

And if your not gonna need the gas tank again, you might want to use an acetylene torch to just cut it into a few pieces to pull out quicker.

Sounds like a back-handed nomination for the Darwin awards!

How do you spell Kablooie? Is it with a "y" or "ie"?
