Fired up my car after grabbing Starbucks on my way to work this week and the red low coolant indicator comes on. Stop by local auto parts store and take a look - sure enough, it's a bit below the fill line, so I bought a gallon of orange and topped it up.

About 10 minutes later while sitting at a red light, I can smell the sweet sweet scent of boiling coolant and start to see steam coming from the engine bay. Pulled a u-turn and headed straight to the dealer.

Sure enough, water pump is the culprit once again. Car has 45k on it and I believe it was last done at about 25k. They also replaced a number of bleed hoses and the crossover pipe. Luckily, I still have 24 days left on my CPO warranty, otherwise I imagine it would have been north of $1k to fix considering the S/C has to be removed.

This has me thinking about what to do with the car once the CPO is up in a few weeks...

 

Ahh, the Supercharger does not need to come off on neither the v6 or v8 to change the water pump, the whole wp job can be done in about an hour. I wouldn't trust my Jag to where you've been going, especially if you are going to be out of warranty soon.

 

you gotta admit...pulling the S/C make the job, much much easier. But the only real reason to pull it is if the y pipe is leaking or the the rear heater crossover...lol...gotta love plastic....by that I mean the C/C kind...not the crap that the y pipe is made out of...hahaha

 

 

New doesn't mean it isn't leaking. I would be on the phone with my dealer right now telling them they didn't fix.

 

Light came back on today, although the coolant wasn't low. Sensor issue or air in the system?

 

Potentially either. I'd run it and let it get up to operating temperature, make sure the cooling fan kicks in etc. Keep an eye on the level as well as letting the engine get hot enough that you might see steam or coolant from a leak.

To be honest though, it may be easier to just take it back to the dealership and let them deal with it.
