99 Cooling message, A/C drain clog, and a Diff leak

[Big Beer]

My first year of owning a 99 C-5 Convertible

When I bought the car (used @ 29,000) miles the owner had it serviced (Oil Changed, fluids topped off and put new brakes on it). I noticed a drop or two of oil on the cement in the garage under the Diff. Cleaned it up (but kept an eye on it, a drip or two after each outting); after a couple weeks of driving it seemed to stop leaking.

First big problem was the Passenger side carpet soaked from a clogged A/C drain.

Next problem was Low coolant message two days after having been serviced for its first oil change (wife see's this I have not).

Fixes...
Well the A/C issue I (ok the wife) had the dealer fix, cost was $60, and they said it was in fact clogged and they were able to remove the debris...That was reasonable in my opinion...hope the problem does not return any time soon (next A/C Season).

Diff leak the dealer confirmed and said it needs a side cover gasket replaced...estimate $425. My thoughts on this is it seems to leak just after being serviced...would I be off base to think topping off the fluids there is just a tad much, as it leaks it gets to its working level and thus stops leaking (talking just a couple of drops per outting for a couple weeks). I Found some other post on this board concerning diff leaks also.

The coolant alarm seems to be related to my wife parking on an incline, I have not looked at it yet, but I am assuming the sensor, may be out of the coolant when on a incline? This seem realistic?

Still happy with the car

HI there,
The diff leak could be simply because it was slightly over filled.
I would clean off the area, and then allow 2 weeks, and reevaluate. The diff vent is on that side.
As for the coolant issue, you are exactly right, if your surge tank is not positioned correctly, this could happen when you are NOT on flat ground.
I would NOT be worried about the coolant unless it appears when on level ground.
Please keep us posted, c4c5

Drove the car through about 3 tanks of gas...no more diff leak.
I am convinced it is being overfilled (what the dealer thinks is full when it is serviced), and coming out of the vent til it reaches its sweet spot.


Thanks c4c5specialist
