Done locally (Ann Arbor), just picked it up yesterday.

 

what do you use for anti-corrosion? I've read water wetter doesn't provide
adequate protection.

 

If u check redline's website it satisfies the stringent corrosion tests ASTM D2570 and D1384 that is used to check glycol based coolants on the market. Who knows but rather have a rust bucket then injure people if it could be prevented. Mike

 

Very OT Mike, but gotta say Megan is one beautiful 6-3! Are those fiberglass doors? What's she weigh in at?

Back on Topic. Yes, much better to hazard some rust than risk somebody's safety!

 

Getty fg doors and thanks : ). With fluids and half tank it currently weighs 2750 wo driver. Still more weight to lose like 150 lbs more : (. Work in progress. Mike

 

1. Megan ROCKS!

2. Halloween is over, but this topic is still mother frickin' SCARY.

Thank you, PAG, for owning up to this... NOT.

Remember what they say about an ounce of prevention. My fittings are done. It's not 'just' the adhesive junctions. It could be the clamps or the rubber hoses.

My adhesive joints were still fine, but one of my hoses was aneurysmal and about to bust. All junctions are now welded and hoses are new and tight.

I've seen 3 GT1s vomit coolant at the circuit, and I could no longer sit on the time bomb. Granted, the ones I've witnessed were all hose issues... but the epoxy issue made me nervous as stink.

Ridiculous!

 

"Although this test method provides improved discrimination, it cannot conclusively predict satisfactory corrosion inhibition and service life. If greater assurance of satisfactory performance is desired, it should be obtained from full-scale engine tests (Test Method D2758) and from field testing in actual service (Practice D2847)."

Better than nothing though. I had my top fittings welded. Will have the rest welded next year as well as switching to water + water wetter.

 

Mine did go at mid Ohio a couple months back but thankfully no damage to anyone when mine went. I was gutted sitting there hoping nothing bad was happening behind me when it happened, I can only imagine what it would feel like if damage would have happened.

 

I wonder if this will be a problem on the new engine in the 991

 

Maybe 3 years ago in a NASA event at TH a 996 dumped oil from
midway of t9 to t10 all the way to t14(caught on fire thereafter) I was one of the 1st cars( 2 cars in front of me) hitting the oily patch going into t10 and car tank slapped to outside then back on asphalt and finally rested on inside part of track. Then 8 other cars behind me proceeded to spin as well and sitting watching and waiting for car(s) possibly slamming into me-man u are helpless. Thanks to the trackgods looking over us -no one got hit. Its wasn't a coolant leak but same slippery goo. The driver of the 996 was an instructor and car's rear end was on fire at exit of the esses so he made a good judgment- he drove his car offline to the closest flag station with a fire extinguisher which is by t14. If he parked it on the grass it woulda started a grass fire(very hot and dry grass day) and car woulda been fully toasted. Mike

 

If you're sitting on the fence about doing something about this problem, please watch my video from Mosport 2010 when a fitting let go on my 997 GT3:
The car stopped 6ft away from a concrete wall and had it been a lap earlier, without traffic, the outcome would have been catastrophic to my wallet and potentially my well being. If you want to see what it's like from the car behind, watch this video and scroll to ~3:30:
Because I'm still under warranty, I run water and water wetter in the summer and coolant in the winter since Porsche won't warranty a car with welded fittings. Please at least do that if you track your car. The cars behind me weren't as lucky with one going into the tire wall on my coolant

 

OVR had a DE at Mid Ohio and a members did let go. One total,one good hit,one spun off in his wake and I believe he knew he had a problem in advance? Was not there but saw the pics of the cars wrecked.

 

H.S.!!! thanks for posting those. Sorry to hear about what happened behind you.

 

Another option to water wetter, is Pencool 2000 (used to called Nalcool) which I have much experience with, though not in Porsches. I would not be afraid to try it.

Porsche should just fix this for all gt1 block cars (gt3's and turbos). Penny wise pound foolish.

Has it ever caused a street incident?
