Borrow a cooling system pressure testing kit from Advance Auto Parts or Autozone and use it to pressurize your cooling system to positively identify the source of your leak. Once you know exactly where the leak is, you can formulate your repair plans without any guessing. To "borrow" the kit, you put down a deposit on your credit card. When you bring the kit back (clean and intact), they apply a full credit to your card. Quite a few of us have done this over the years. It pinpointed the coolant outlet pipe leak in my wife's 2006 XK8 back in November 2014....

Be aware that the plastic coolant expansion tanks in these vehicles are always prime suspects for leaks. The plastic is not very robust and after baking in the engine bay for just a few years, they all eventually leak at the hose nozzles or seams (or both)....

I know many of us avoid draining the cooling system when working on it because the Radiator Drain Petcock is fragile. I have found a replacement.

If you google: Dorman 61138 you can find what looks like an exact match. It can be found at Rockauto, Advanced Auto, Autozone, and O'reilly. However, none of the local stores had it in stock, but they did have it available to order. Rockauto's price is the best at $3.55 plus shipping. Hopefully I'll have it here by the end of the week and can report back on the fit.

It also fits about a thousand different Ford models including the Mustang Cobra SVT from '04, the Ford Fiesta, the Focus, the Countour, among others.

You can also use a $5 siphon hand pump from Harbor Freight to pump out most of your coolant from above. No messing with the fragile drain petcock required....

Can you reliably get to the bottom of the radiator from the upper hose connection?

No, you would have to remove at least one of the lower hoses....

If some one needs a replacement tow hook for an 2003 XK8, (with the M20 x 2.5 RH thread arrangement), one for a 2007 Hyundai Accent works perfectly for the front and rear. Best of all it was only $3.25 at the local salvage yard.

The petcock arrived and I installed it. It's a two second affair, just pull out the old one, push in the new one and screw it in. For the price, I would rather deal with the petcock than with having to get the radiator hose out.

The new plastic feels far less brittle than the old petcock. I highly suggest that if you still have the original one, change it out for a new one the next time you need to drain the radiator fluid.

The old one was a goner. The rubber o-ring was torn when I removed it and the Philip's head was abraded.

For a rear parking assist sensor a YDB000121 will fit but orients the oval lined face the wrong way. Up and down instead of side to side because the locking tab is not oriented in the right spot. The locking tab can be cut off and reglued or epoxied into a correct position. It fit my 2003 XK8 once modified and now my parking assist works perfectly. About $10 on Amazon.

If you need one with the circle on the face of the sensor the C2C29376 should work perfectly per Zray. About $11.35 on Ebay.
