Dual Coolant Control Valve

Dual Coolant Control Valve
My girlfriends 2005 4.2L s-type is having a problem were the driver side blows only hot air, but the passenger side works correctly. after searching on this forum it seems most likely to be the DCCV, and seems to be a fairly common problem. I saw people making references to another car that has this valve, but noone ever seemed to know what car it is. I called up jaguar today and they wanted close to $350 for the part so i am trying to find another place to buy this valve as i doubt i can find another s-type in a junkyard around here. Here is the information i found so far, it seems that either a 2002 ford thunderbird or a 2000-2002 lincoln ls. ill let you guys know if i find one that works and the cost.
Here is the test procedure for the thunderbird to see if the dccv is functioning properly

Before you go replacing parts it would be wise to read previous posts on this and other forums. Failure of the wiring loom results in the valve(s) defaulting to open (hot) due to a lack of a control voltage to close the valve(s).
The dodgy wiring loom is a common fault, usually in the area of the front bumper.
You will need to check what voltages you are getting down at the DCCV.

So far i have found that jaguar wants $337 lincoln wants $250, and ford wants $267
Ill look into the threads on testing the voltage. So far the only thread on faulty wiring to the dccv had a test that did not involve testing voltage, it just had a procedure, and since the passenger side temp goes up and down i did not think that was the problem.

im not "sure" that the ford/lincoln one is the same as the jaguar one. i am sure the lincoln and ford ones are the same as they have the same part number. I have heard people make refrences to using the valve out out of the lincoln. ill call jaguar and get the part number off of their valve and we can compare it.

here is a picture of the valve, judging by all the orange stuff on mine i think its not working.
you cannot really see it from the engine bay, its way under the car you have to take the skidplate off to get to it, but if you are wondering were it is, its basically directly under the brake block. here

on a side note, is this the most complicated coolant system you have ever seen?

As long as you run long-life red/orange coolant that meets M97B44-D standards, you'll be safe. As has been pointed out before in a previous thread, look for the M97B44-D specifications on the label before you buy your coolant. Most decent long-life red/orange coolant being manufactured today meets those specifications. But check the label to ensure you're buying the right stuff.
Problems (usually gumming or gelling) occur when you mix old-style green coolant with vehicles that require red/orange coolant. Their formulas are not compatible.
