Coolant Bleeder Screw

troyer · 05-03-2008, 06:17 PM

I thought today would finally be the day that I got my car on the road, for the first time ever, but I snapped the head off of the coolant bleeder screw while tightening it, and coolant is squirting everywhere.

I looked it up on 944online.com. At $6.95, it's not that too bad, but considering the $12.95 for shipping, and the days it will take to get here, I'd really like to find an alternative.

I'm thinking that I could probably find some generic bleeder screws at the local parts store, but I have no idea what the thread size and pitch is. Does anybody know? Also, if I can't find a bleeder screw that's the right size, is there really any good reason why I couldn't just use a normal screw, and just completely remove it in order to bleed to cooling system?

Post a WTB in the calssified section. There are a few guys in OH that are parting cars out.

I used a replacement from the hardware store but eventually replaced it with a new bleeder. The original has a hole drilled thru the stem to assist air bleeding out and a o ring....iirc. But a normal bolt of like size is doable. M8x1 iirc is the size you need. It will be messier if you use a aftermarket bolt when bleeeding as the bolt basically has to come out completely where as the OE bleeder can remain partially threaded and release air.
12 NM torque on the OE bleeder.

M8 x 1.0 x 12mm long. I have looked in all the usual hardware-type stores and couldn't find that size anywhere.

Maybe just order some oil filters or hoses, general maintenance items that you will need eventually anyway, to help justify the shipping costs?

I've not checked out the classified section yet, but I'll have to do so. By the way, I got the relay... worked great... thanks.

M8 x 1.0 was a bit hard to find. M8 x 1.0 x 12 was not available. I ended up with a normal M8 x 1.0 x 16. The extra length was not a problem, other than being annoying to tighten.

I got the car out for the first time ever... The brakes barely work, and the steering is hard, so I'm sure I'll be buying more parts. If I don't find a used bolt, I can combine shipping at some point.

I believed older Honda CRXs, Civics, and Accords used same style bleeding
screws. I am not sure what size. but you can find one at the wrecking yard.

$ 12.95 shipping for the size of this screw is a bit funny.

Sometimes, one must look for more than one Porsche parts supplier and compare the price. Have you checked the Porsche dealer , or Porsche wrecking yard?

I can get thousands of them, why you have trouble is a mystery though! Well it maybe just a tad long, use a washer.. But do not over tighten, this is what snapped it in the first place. The material is like "pot metal or Peuter...sp?......Pays to use the torque wrench in inch lbs if possible.

just use a normal ace hardware bolt for short term until u find a replacement. it'll work just fine. but it'll be kinda slow to bleed since it's just the gaps in the threads that's bleeding the air. but totally safe

Exactly^^^...Remember the hardware one is steel and will rip the housing up if you tighten too much so just make it snug and go until you can get the OE replacement. Helps to use a cork washer or o ring to take up length and seal better.
