So, I fired up my 944 for the first time this spring on Thursday and Friday. Tonight I took a quick look under the car and found a couple spots of coolant., probably not more then 5ml. They were located on the passenger side in front and inboard of the wheel. When i swiped my hand under the following hose I found it was wet.


You can also see coolant on one of the fins of the timing belt cover in this pic


I tightened up the hose clamp a bit but it seemed pretty tight already. Anything else to be done? Could it be coming from somewhere else then the hose in the picture? I never noticed a leak in the fall before I prepped it for storage. Since I'll be replacing the coolant here in the next month, should I order a new hose and clamps just to be safe?

Thanks!

 

Your best bet on finding leaks is to go to Autozone and borrow their radiator pressure testing pump. You don't need a lot of pressure ~10-15psi. Pump it up then look for the leaks. Common leaks in that area are; the small elbow hose that rests against the oil filter, gets chafed from removing oil filter with a cap tool. Also, could be coming from the oil cooler housing seal, as it was in mine.

 

Any other input? Does the hose look normal, or does it appear to be expanded compared to normal?

 

I had some leaks from the same spot recently (something kept dripping on my face while I was changing the motor mounts) I tightened the hose clamp a bit more and it's been fine since. Used a rented pressure tester from Autozone and it held pressure just fine. I've also had to tighten the smaller hose that is just below the primary one in your pic.

 

I've run it a couple more times since I first spotted the leak and have not found any more wet spots. Might just have been a bit of a loose hose after the car had sat in the garage all winter.
