Hi all. Im working on a 2000 996 that is overheating because of no coolant circulation. The left and right hoses coming from the engine gets really hot so I know the thermostat is opening but when I went under the car and touched the large hoses underneath that delivers the coolant to the radiators, these hoses and pipes are really cold. So I thought the water pump is defective (although not leaking) and maybe the plastic impellers are broken. I took the pump off and after inspection, it seems the pump is in good working order. No broken fins, bearing is tight and doesn't wobble. Is it possible the pump is defective even though it looks like in perfect working order upon inspection? Basically, the water is not being circulated and not reaching the radiators. Any suggestions? Thanks. ***EDIT: Nevermind, waterpump is good, just had to give the engine a few hard revs to get the coolant circulating.

Lost Radio Code - post your request here

Hi Loren, I'd like to request a radio code: CDR-220 Type 4362 Serial X5018260 Thanks. -
Car stops running after heats up.

Bump, still waiting for an update. -
I spoke to a tech and advised me that whatever is causing the car to shutoff after warm up is not related to emission components such as the charcoal canister. He mentioned that it is definitely heat related and that the car is not able to restart until the components affected completely cools down. Anyone?

996 Engine Picture Request
cosorio replied to cosorio's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
Thank you. :) -
Hi all. Could someone with a 2000-up 996 with E-Gas post a picture of their engine? I need a shot specifically on the throttle body. Thanks.
-
99% and you should hope that it is an RMS leak because another possibility is a case leak which is infinitely worse as you would have to split the case just to reseal. An RMS isn't too bad of a job: drop the tranny, remove the clutch and flywheel and you're right there.

I am leaning towards concluding that code 0446 is not the cause of the engine shutting down after it has warmed up. I just replaced the carbon canister and used a friend's shutoff valve and purge valve and the car still shuts down each and every time it has warmed up. Again, the parameters are: engine shuts down after warm up, usually a few minutes after startup, and will not start again until after several hours have passed. This is usually overnight. There are no other codes present. Now Im thinking either fuel pump or relay. Is the ECU the unit that shuts off the engine and prevents it from restarting until after a number of hours? The car is a 2000 996 manual with e-gas. Thanks.

Have you resolved the problem? Please post how you fixed it as I am having the same exact issue. Thanks. -
Time for an update. I replaced the carbon canister with a new one and the car still shuts off so we can eliminate that as the problem. Next thing is the shutoff valve. I located the carbon canister vent valve housing which houses the both the carbon control valve and the shutoff valve. If the shutoff valve is at fault, would I be able to test it by simply disconnecting the shutoff valve and the car will start again? When the car shuts off, I no longer get the fault code with Durametric.
-
I think one of the actual values in durametic is a reading about how saturated the charcola filter is - you might want to take a look at that value. I think I know which one you are referring to, and the reading is -6.
-
Well i checked the 2 lines in the engine bay and neither seems blocked. I started the engine again and ran the durametric and no codes showed, but the car still shutoff as usual. I guess I'll have to locate the charcoal canister. Im assuming the canister and shutoff valve are located under the car next to the tank?
-
Thanks Loren. I will post my findings when I diagnose the problem.
-
Thanks Loren. Which is the purge air line that I need to check for blockage? Is it the top port of the canister? Would you have a link to a diagram? Would this actually cause the engine to shutoff? Thanks.

Hi everyone. I need help in figuring out the cause of the car shutting down after reaching normal operating temp. The car is a 2000 996 with E-Gas and it is coming up with codes P0446 - Shutoff valve activated-charcoal filter (function) and P1674 - Final stage engine compartment purge fan. I have read a lot on past posts regarding P0446 and the charcoal canister but I do not believe I have read an occation when the engine actually cuts out. After shutting down, the car would not start again until the following day, or after numerous hours have passed. Does anyone know if the charcoal canister just need to be replaced or is something else involved for the car to shut down. Also, where is the shutoff valve located? Thanks.
