general problems of the 2002 Porsche 911 Turbo

The car was being driven under normal circumstances. I had catastrophic coolant failure. A hose on my coolant system popped off while driving causing all of the coolant to gush out of the bottom of the car, the car did slip a bit I was able to regain control and pull to the side of the road. It sounds like this issue happens to 911 Turbo's often due to the fact that 8 hoses were attached only with a glue that can give out at any time. My local Porsche shop wants $3000 to drop the motor and repair/fix the 8 hoses. From my reading online this issue happens often to this motor in cars from 2001-2013.

Coolant line became separated and dumped coolant all over the highway causing very slick road conditions. This was on a long highway road trip with the engine very warmed up and working. Failing coolant lines that dump are very dangerous to those behind the vehicle, especially at highway speeds.

Catastrophic loss of coolant due to coolant fittings popping out. Low speed, straight line driving at the time so there was no excursion, however rear tires were seriously wetted and if I had been in different circumstances it could have caused vehicle/property damage and/or personal injury.

Discovered numerous Porsche cars with gt1 block engine pre 2010 that are water cooled have coolant fittings that are known to fail due to a glue that is not holding up. As such, driving can suddenly release coolant on the ground causing the car and those cars following it to crash without any warning. This affects 996 and 997 turbos and gt3 variants. The topic is described on rennlist. Com, renntrack. Com, and a vendor actually advertises a fix (sharkwerks. Com). One group of Porsche driving club users will not let cars without this being mitigated to participate in group events due to safety concerns based on a big crash in 2012 at the midohio track (may be 2011). Non track, street crashes and incidents are documents on the internet. This group of cars is a huge risk to all others on the road in addition to themselves. Someone is going to get killed and it seems to be accelerating in frequency. . Read more...

Glued in coolant hoses came out dumping all the coolant from the car in a very short period of time. Since this is a rear engined car, it sprayed the rear tires causing a dangerous situation as loss of traction could have caused a serious accident/fatality if going into a curve or other conditions. This is a known condition with Porsche and they have refused to address this serious safety issue.

On two separate occasions, the coolant fittings which mount in the cylinder head popped out. The fittings attach to the coolant hoses. In both cases the epoxy that held the fittings in had failed. Each time I was driving and coolant spewed all over the inside of the engine bay and then subsequently onto the road as I was driving. The first incident I was driving about 50 mph (10/19/11 - 52230 miles on the odometer). When this first fitting popped out, since it was behind the alternator, damaged it requiring replacement of the alternator. I had to pay for the alternator and epoxied that fitting out. The second fitting failed on June 14, 2012 with 56384 miles on the odometer. This time it was in a location that required removal of the engine. The circumstances were similar to the first, around 50 mph and coolant dumping over all over the ground. Since this happened a second time, the shop I took the car to removed all 8 of the coolant fittings in the engine, removed the epoxy, and then welded them into place. After two of the fittings popped out, I was not going to take any chances of another fitting popping out and being left stranded yet again.
