by the picture it looks like 996 106 501 74

 

This hose tends to hit on the engine mount under heavy acceleration and overtime will fracture like this, I've had it happen on the drag strip, not a fun experience Use a pressure bleeder to pressurize the coolant system and allow you to add more coolant.

The part number should be on the hose itself, if you can snap a picture of which 1 of the 2 hoses it is in the engine bay I can get you the correct part number.

 

mr. swed and one love, thanks for reply. Mine aren't busted, just want to do preventative maintenance while the engine's out. The photo is from the OP of this thread.

Are both problematic or just one side? Suppose I should just replace both for good measure but it's good info to keep mind of and inspect from time to time.Guessing more solid than OEM engine mounts may help.

thank you

 

I would go ahead and replace both. The one closest to the motor mount is usually the culprit, but the o-rings can also be a problem when these hoses are removed and reinstalled. I would replace both hoses and the o-rings on the couplers at the same time.

 

awesome, much appreciated.

 

I/C to Y pipe has a flange both ends.

 

Just checked pelican for the coolant hoses. The old part numbers given above have been superseded by 996-106-501-76-M100 & SS 99710650200
