Coolant Leak Diagnosis: Cracked Reservoir?

Recommended Posts

I noticed a nice puddle of coolant under the left side of the car after pulling into my garage. There was a fair amount of coolant on the floor... I have lost about 1 cm in the height of my reservoir.

Coolant leak pics

Anyhow, I jacked her up and took some pics. Initially, it looked as if the coolant was dribbling down the left side of the motor onto the driver's side header (first pic).

Getting up under the car, it looked as if the dribble was originating higher up (see arrow in second pic).

After leveling the car, the dribbles moved. <_< Now, they were dripping from the left exhaust tip. As far as I could see, the leak was probably coming from the coolant reservoir tank. No coolant around the cap. Coolant valve was closed. No other signs of coolant in the engine compartment that were easily visible.

The third and fourth pics show the hose just up under the coolant reservoir. It appeared as if coolant was dripping down on top of the hose, probably from the tank but I could not clearly identify the leak source.

So, I think I have a cracked coolant tank. What do you guys think? I plan on calling the dealer in the AM and will probably end up driving her in, unless the level falls precipitously during the night.

Thanks for your help! :)
