<p>Hello everyone. So I was thinking about changing out my Dual Climate Control Valve today after work. I have access to a lift. Will that make the job a lot easier?</p>

2003 Jaguar S-Type V8

 

I just did mine ('05 STR). Access will be crowded with hoses. You will want to access from the top down.

I have a lift and took a look from underneath while dumping the oil. Not really very good access that way. Front frame cross member is in the way.

There is 1 M6 bolt holding the unit in. Can't recall if 8mm or 10mm to remove.

I used the Ford valve to replace. $127 vs $436.

Good luck with your replacement.

Thanks STRCooper. I picked up the Ford part myself from a local auto parts store. Cost me $150. Now I read in another thread that if you change the DCCV you should flush your coolant and and and change your thermostat as well. Did you do all that as well?

 

I actually just replaced all of the coolant hoses and flushed system. Big job, but had a leaky hose and 90k on car. This is our primary family car, so I did all hoses.

Decided to skip thermostat as it is working and also easy to get to.

Replacing all the hoses is actually not a bad idea. I was looking at that aluminum aftermarket thermostat housing that comes with a new thermostat on welshnet. I think I will go that route with that.

Also is there a radiator hose replacement kit? I should go ahead abd replace the hoses. Do you have any recommendations on that?

 

The radiator/heater hoses are all sold individually.

I just went through EPC and pulled out diagrams/part#s for the individual hoses I thought I needed.

The parts guy at dealer reconfirmed and placed the order.

(Keep in mind the R has myriad of extra hoses for supercharger cooling compared to the V8)Joy...

In addition to main Rad. hoses you should consider the other hoses running off of the coolant resivoir.

There are LOTS of threads / discussions on this forum by people who've also done this repair. May I suggest you do a search for DCCV and read as many as you can. This will arm you with lots of knowledge so you don't repeat their mistakes. A little research goes a long way.

 

This is how i did my 2000 S-Type 3.0

Different DCCV

 

So I'm currently in the process of changing out my dccv. The hose at the bottom of the dccv seems to be welded on there. Any advice or special techniques you guys would like to share.

 

I always use a hose removal tool like this

 

Assuming you want to reuse the heater hose, I have found that the very careful use of a slim flat blade screwdriver inserted into the edge, then under the hose, will break the surface tension. You can loosen the easy to reach areas this way, then follow up by using slip joint pliers to grab the hose and rotate it. This will break the remaining surface tension.
Then twist/pull off the hose by hand.

For re-installation, use a little bit of pure silicone grease on the nipple of the heat valve. The grease is very sticky to the touch, but man do the hoses slide right on!
Available in the plumbing area of most hardware stores.

Glad the project is coming along.

...and what a project it is. I had to call it quits last night very frustrating. I will def finish it up once I have the proper tools.

 

Better pick up one of these, too!


(3 DCCV changes in 3 mo.)

 

Don't even attempt it unless you have the cable pliers shown above. They are required!! I did not even know about them until I did my DCCV and could not get several clamps off. They really help in the tight spots.

I leave the hoses on the DCCV and remove the other ends. The three heater hoses are a bit easier to get to and use the push lock type connections.

Tbird6: I only have 3 hoses on my DCCV. Went to Sears on my lunch break and picked up the remaining tools I needed. I love that place. My buddy and I are going to take a crack at it tonight.

aholbro1: 3 DCCV in 3 months. That is ridiculous. What happened to where you have to keep changing them so I won't make the same mistake. Lol

 

Hahaha, would've probably been 3 in 3 wks if school wasn't in-session!
You've already avoided my first mistake...by waiting until it fails to change it! Pre-emptive maintenance, in this particular instance, definitely not all it is cracked up to be:

Got that lil sucker out last night and now A/C is blowing like a champion. I thought I was going to have to take apart my climate control module and solder those connections back there. Since A/C is blowing like it should I guess there is no need.
Thanks guys for all your help. I really appreciate it.

 

Hey guys,

Thanks for this.... I have now bought the tools, ordered the valve and will give mine a go once the bits get here.

Actually feel confident....

I'll post how I went.


Cheers,

Doug
