When I took my car to Eurocharged to get the pulley and tune, they showed me a coolant leak I have. It seems to be right under the throttle body. What is this? The thermostat? or water pump?

 

that's the water pump. thermostat is not shown in pic.
also, there is another hose that connects at bottom of throttle body (from rear crossover) that could be the culprit.

 

Not a hard DIY

Just take your time.

 

does the water pump sound like a bad bearing when it goes bad? like in my video below? i also see the pulley wiggling

 

LOL, on a 10 to 1 count down to failure, your WP is at 2. Just know if you overheat a Jag AJ133SC due to a failed WP, you'll need head gaskets too.

 

Lol yes, get that pump changed out now.

 

so SC has to come off to change the plastic tube? can the water pump be changed with out that being replaced? how many hour job would you say?
I actually have the extended warranty but that's a $250 deductible, if I can do it my self for less, then I'm all for it.

 

No the SC does not have to come off to do anything in changing the WP or plastic tube, I had my SC off to facilitate the replacement of the plastic crossover tube on the BACK of the engine.
You want to change the plastic tube and WP at the same time. If a $250 deductible is all that's holding you, back pay it and get it fixed now.

 

Don't know what engine you have, but if it is the 5.0, be sure to replace the plastic crossover pipe if you replace the water pump.

 

got the pump and the little plastic snout that goes on the back of it, but not the whole plastic crossover. Going to do the replacement my self today. It wasn't the $250 that was holding me back, more the fact of the dealer said they would need the car for 2-3 days to fix it... when I can do it my self in a few hours. I don't want to be with out my car for that long, lol.
From what I see, the swap is pretty basic, like doing an alternator on a normal car, since this is belt driven vs timing chain driven.

 

yup! looks a little bad i would say... lol
