I just found coolant leaking from the passenger side of my LS V8 04. I popped the trunk and the it looks like it's coming the DCCV. It looks wet and like some mold is on top of it. It's leaking pretty bad. Could it be one of the hoses? Has anybody had this problem?
 
I have looked at that post a few times and been thinking about doing it a few pieces at a time. Expensive job and I can't do it myself so I would have to pay a mechanic. I guess I'm going to have to take it in today to see where this leak is coming from. It looks like it's coming from DCCV.

You have access to the DCCV via the trunk? That's Fn AWESOME!!!!

Wish mine was that easy to get too ... like others, I had to get all cut up on the inside of my arm due to the tight fit messing around near the radiator shroud, which is kept under the hood of most LS'es.
 
Yup, I'd start with under the hood also, trunk is only needed for water leaks and battery disconnects. <fix transmission>
 
An low cost or no cost solution to find it is look up a real radiator shop. Now I see your in NYC and its a hard nosed and high price city to fix a car. But look up under radiators NYC or maybe N.J.ersey and let them do a preasure test which can show up the leak. In Ohio a est would be 20.0 -25.00 or sometimes if its not needed to be on a rack its free. WHAT IS A DCCV
 
Pressure test is unlikely to help. The DCCV on my 06 failed this way (external leak), and it went from no leak to big leak very quickly. I bought an aftermarket DCCV, as I had to fix it that day and keep it on the road. The aftermarket only lasted about a month, but that was long enough for me to order and get the Motorcraft DCCV.

As for not having the money to replace all the plastic cooling system parts at once, it will cost you more (maybe way more) to do them a few at a time...

PICS: Dual Coolant Control Valve


These so called solenoid valves can become stuck in either the open or shut position, most cases only one side jams up.

During A/C use when the passenger side blows hot air yet the drivers side provides cooled air, it's a sure sign the DCCV needs replacement.


different P/N's on the DCCV for either GEN

1st GEN = 5 in/outlet tubes.
2nd GEN = 3


The Dual Automatic Temperature Control (DATC) commands the Dual Coolant Control Valve (DCCV) to allow for more or less hot heated coolant to enter the heater core.

#5 is the Dual Coolant Control Valve P/N 18495

I did up an article some time ago, there is more info there ... GEN I - Understanding Climate Control System - No Heat Information



EDIT - - - and it's found under the hood not in the trunk :p
 
Well the verdict is in I had a leak in the upper radiator hose, crack on thermostats housing and leak on the DCCV.

Surely, you must realize that everything else is cracked too (or will crack as soon as the others are fixed and the system can pressurize again). Do it all, now.
 
So after replacing the parts I just mentioned what else do you recommend replacing on the list?
 
This is what happens to these aging LS'es, the entire cooling system plastics needs replacing and as pointed out several times over by many on here, it's best to do the entire system all at once if you want to be able to obtain an air tight system so it can be bled properly. If only piece by piece is replaced, it strengthens it in one area and will only continue to be a problem in another area.

All the way from the Degas bottle, in and outlet pipes, thermostat housing to the DCCV and a times new radiators are needed. The Plastics that make up 90% of these cooling systems deteriorate over time and become weak and brittle.

same old, same old. Open wallet and grab yourselves a cart.

Very doable for even the modest DIY'er, all the info needed is available on this wonderful forum.

Thanks guys for your help. I love this car but damn it's expensive to maintain. I was planning on putting in my new brakes from rotor pros but that going to have wait.
 
It really isn't though. If you pay someone else to do it, yea sure labor is expensive - but that doesn't depend on the car so much.

I replaced all of the cooling pieces in just one night, and that included cutting the elbow piece bolts and wrestling with the oil cooler hose clamps for WAY too long.

Shop rockauto and ebay for the cheapest parts, just follow the part numbers and get everything Motorcraft.
 
I'm not that mechanic savy with cars. I could a couple of things. And I also live in Manhattan NYC. No drive ways and just trying to find parking is crazy so trying to do all this stuff in the street would be difficult.

Thanks for the info in this post, mine is leaking now (a/c stopped working last fall before parking for the winter(

I finally changed mine, the a/c stopped working awhile ago then the dccv finally started to leak slowly then very progressively. At first I thought maybe it was one of the hoses but after an inspection and reading a few of these posts I quickly realized the DCCV was NFG... I picked up an OEM part for $220CAD and swapped it out fairly quickly. I could've found one cheaper on ebay, but by the time I pay to get it across the border(Canada) and pay exchange/duty plus waiting a week and burning the deisel in my dodge..the costs worked out.

Thanks for the good info here Fella's

P.S. I found my DCCV under the hood as well
 
Yes. I had a cousin in Long Island NY . Flat rate labor is 70 an Hour in Ohio. New York City shops charge more .
