jasmus1 posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I have a MY 1999 996 C4 that I had to have towed because of a coolant leak. I saw smoke coming form the engine area so I pulled over, saw the leak and thought it best to get a tow. I initially thought it may be a hose leaking, but found that when I squeezed a hose, it looked like coolant was leaking from the lowermost flywheel (where the serpentine belt goes). Is this possible or could it be leaking from somewhere that I cannot see? About 1000 miles ago I had a new clutch, IMS and RMS bearings installed. Could any of these repairs be related to the coolant leak? I want to try to fix this myself before having the car towed for repairs if possible. Thanks in advance for your help!
The lowest point on my '99 996 Tip is the radiator hose to the hose. I found this out the hard way. If you bottom out your Porsche, the hose gets scuffed and can cause a leak. After a good person warned me I was spewing something bad, I pulled over and saw the problem. Here's is what to do: If there is an auto parts store really nearby, race to it. Otherwise shut it down. Hopefully, your are in the city and can get the the auto parts store. If not, tow it. Buy a section of 1 inch radiator hose, straight, and two 1 1/2 inch hose clamps. Cut the hose about an inch longer than the tear. Slit open the hose. Wrap the new hose around the tear and secure using the two clamps. My tear was next to the engine inlet, so I had to remove the old clamp. If so, make sure you place the new clamp around the inlet. Note: if the leak stops spewing before you can fix it, you lost about three gallons of coolant. Allow the engine to cool. Then fill with coolant, 50/50 pre-mix. There will be trapped air. Note: even though the temp gage says its cool, the coolant may still boil over. If so, wait more. Check for leaks in the patch. Now drive the car a short way, keep an eye on the temp gage, aim towards a car wash. If the temperature climbs towards overheating, stop and allow to cool. Check for leaks. At the car wash, was car of all coolant and cool down the engine. The fill with coolant. There may still be air trapped, but you shouldn't have to wait for the engine to cool before filling the coolant tank. Now drive car cautiously. Look for the coolant level warning light. It is next to the over heat light on the temp gage. If it goes off, stop and fill with coolant. The patch should hold until you get a new hose. I am going to leave the patch on the new hose in order to protect it.
New to this Board and looking for some immediate guidance on a specific problem with my coolant reservoir (leak). If anyone can answer this, it would be greatly appreciated. I have an 2001 S with 65,000 miles. I noticed the aforementioned coolant leak. I've ordered the #01 new style cap (wish Porsche had bothered to tell me about that one!) and am waiting for it. in the meantime I am either trying to seal the leak with some plastic weld that another user had success with - OR - I will try and replace the tank itself if need be. HERE'S THE QUESTION THOUGH: In every posting I see it refers to just how difficult this DIY job is because "you have to remove the hoses from inside the engine compartment on the other side of the firewall", and "almost need drop the tranny to get to the c-clips". BUT MINE SURE DOESN'T LOOK LIKE THAT! (See attached photo) All I'm seeing are three rubber coolant hoses with c-clamps on both ends, and the oil fill tube, and the oil dipstick line. That's it! So I am left wondering if my build got a newer style coolant reservoir that is easier to remove - OR am I just that stupid and asking for big-trouble in trying to do this? Anyone know if I remove those three hoses can I A) either move the tank around enough to get to the underside and REALLY seal the leak? OR 2) remove the tank entirely and replace it myself? Oh, man thank you if you know the answer!
sullivas posted a topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)Anyone know if the Prestone bulb & arrow type coolant tester works accurately with our pink Porsche coolant? Thanks
1999 Boxster S Tiptronic 57K miles. Spent good part of the afternoon trying to get to the bottom of coolant loss from the expansion tank. Wife went to use the car yesterday and the red light started flashing, checked the expansion tank - empty. Took about 3 litres to refill. Today I went through a 'bleed' procedure. Pulled up a spring loaded clip on top of tank, slowly filled tank, remove a fuse B1 to effect some sort of valve - apparently only needed for tiptronic system bleeds, run engine up to 90 - used cooking thermometer into expansion tank, reving engine every few minuets. There was a visible flow. The tank spilled over when it hit about 90(when the stat opened?) then settled down fine.This process took about 40mins. Reset spring clip, refitted fuse(which stopped the instruments working whilst removed), closed tank lid and took car for a spin. After about 6 miles steady driving pulled over and checked tank level - all good. Did another 6 miles with a blast up to about 6K revs in 3rd. Got back home and pulled over. all good. Ticked over for a few mins fine. Did one more lap of the block and pulled over; a large gush of water came out of the top of the tank -about 2.5Ltrs on to the road. Back to square one. Is there something I'm doing wrong?
