Ed, I agree it's more than likely the pump, but I figured for 30 bucks or so, I'd hope against hope and see if it was the hose.
Leading evidence: 'hose' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'hose' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace own pump, or have it done' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

More than likely the issue is the water pump, but it doesn't appear that any coolant is leaking down onto it, the issue appears that the hose itself is leaking, and it looks slightly bulged.

Shark, did you replace your own pump, or have it done?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

This hose is leaking coolant. From what I can see, there are two of them, one on either side of the engine. The one that is leaking is the driver side. I'm looking for a part number if anyone knows it. This picture is not from my car, but it's an image of the hose that is leaking I found on the interwebs. Any help would be appreciated. More than likely the issue is the water pump, but it doesn't appear that any coolant is leaking down onto it, the issue appears that the hose itself is leaking, and it looks slightly bulged.
As always, thanks!
be careful - if the water pump is leaking it can look like its the hose - water pumps leak out of the center of the pulley
remove the belt and see if it wiggles
Thanks for the info, that's what I was thinking but wanted some confirmation. Ed, I agree it's more than likely the pump, but I figured for 30 bucks or so, I'd hope against hope and see if it was the hose. As well, the hose does look bulged, so replacing it probably isn't a bad idea anyway.
There are two versions of that hose coming out of the pump.
The new one requires a new hard pipe attached to it as well.
The old one (if you can still buy it) should be a direct replacement for whats on your MY 99 car.
No sorry I don't know when but I do know the superseded part (replacement for the orig) is different from the orig (which is NLA from Porsche).
It could be just very early 99 models with the old hose style, but all of the 99's I've seen have the old hose style.
It is possible your car already received the "updated hose and hard pipe" at some point during it's service history.
It's easy to see, the difference between the hard pipes. The new one has a nearly 180 degree hook/turn before it goes into the water pump hose. The old one just turns about 90 degrees (or less IIRC).
Won't know for sure until tomorrow, as shipping didn't go out when Suncoast thought it would, so instead of Friday, will get it on Monday.
Shark, did you replace your own pump, or have it done?
you can remove the belt from the pulley's and check for "wobble" in the WP in about 5 minutes - would save you waiting twice for the mailperson (PC for mailman)
Kyle changed his own - search his epic thread "going in alone" - he's an Upfixen guru
No kidding! Just read the post, nothing like doing your IMS on your garage floor, fantastic! Ed, what am I looking for with the wobble? Any lateral movement at all, or more than a few mm's? How much if any movement and I looking for?
Thanks,
DS
Update: Took off serp belt (replaced it while it was off, and it definitely needed it). Anyway, it's the pump, as I initially suspected. I've read the write-ups, watched the DIY's, and pretty sure I'm going to tackle it myself. Anything I need to be aware of that isn't overly aware in the write ups? Finally, I'm assuming about 3-4 hours to get it off, and put the new one on, with a few beers inbetween...does that sound about right, or am I way over or under?
Thanks,
DS
Yeah, no wiggle on mine, but I could see by turning the pulley on the WP it was seeping coolant at the corner. So, going to order a new one and pull out the old one, and put in the new one.
