Ahhh, that's better :SOMBRERO:

ambient temperature 12*C
25 minutes to warm up with occasional fast idle between 1.5k and 2k.

Card board was left blocking the radiator but I don't think it was needed. I didn't feel any warmth in the upper rad hose until I neared the proper operating temperature.

Papaindigo - probably from a Kia then. I am going to keep the truck a long time so I may need to know this one day.

It is a 98 kia sephia I believe. There is a year range that it covers and specific engine size (1.8L i think) that it goes to. I am at work again so do not have access to my parts list right now, but I am pretty sure that is accurate. May go a coupple years up or down on the application for the same part. I'll check that when I get home again.

*EDIT* I was correct: Water outlet - 97/98 Kia Sephia 1.8L

Thats exactly where the OEM thermostat I put in 2 weeks ago is running :SOMBRERO:

According to my VAG-COM the coolant temperature is 176*f. That's a far cry better then the 157*f on a 90 plus degree day with the old one. I aimed my laser pointing infrared thermomentor right at the head where the thermostat housing bolts to the head and obtained the same reading :BANANA:

I installed the 192*F thermostat for this reading. I haven't checked it with the scanner but I did do a boil test. These dash gages are probably not too accurate but I did come close to the picture on the first page of this thread.

If/When the modified thermostat housings become available put me down for one.

PM Mark to get on the list.

My CRD will never reach operating temp at idle. My other modern diesel (98 NB TDI) wouldn't either. I just sold a '78 Rabbit IDI diesel that would warm quickly at idle. Never really sure why, except that the compression ratio on the Rabbit was much higher. . . 23.5:1. Then again, maybe the pre-chamber distributed heat more readily?

MY CRD will lose engine temp coasting down a long downhill. Make that a descent of several thousand feet. As soon as normal power is applied, it rises quickly back to normal temps.

Most likely your mileage will not vary.

New CRD owner here.

I read this thread yesterday having no idea that there was any issue. After driving around yesterday it is obvious that my thermostat is also having issues. The guage never goes above abot 1/4 of the travel. I seem to be getting pretty good fuel economy, but it would sure be great to do better.

So sign me up. I will send a PM to reserve a spot in line. Thanks for all your efforts in this! :BANANA:

My stock CRD is at the second line to the left of the 1200 line, is that a good or bad thing? once it warms up it never moves.

The factory thermostat normally sits 1 line lower than the middle mark. The 192 sits about 1/2 a mark from the top. As the temp approaches the top of the gauge the temp doesn't change the needle position much. If your sitting below the first mark to the left, your thermostat is probably starting to go. Most people sit where the drawn in orange needle is when it has gone out completely. See diagram:

Hey, our Jeep Grand Cherokee has been keeping me busy fixing lots of little stuff thats broken/neeeding adjustment. The lift had a couple improperly installed things and needed some TLC. Everything there is good now, but still have alot to fix on the GC. I will get back to the thermostat project as soon as I get the Grand Cherokee up to par for daily driving and coming winter.

You know, Mark: It's not too late to get back into a CRD to get rid of all those pesky maintenance problems :wink:

OldSkull · **Posted:** Wed Oct 27, 2010 7:06 pm

Or better....Change the gaser for a 07 or 08 GC CRD :mrgreen:

The problem is finding one for cheap or find a way to sold your thermostat design in Europe and get rich! :roll:

I suggest you get a patent for it Mark before they copy your design, It's maybe just a hobby for you but you overlook the potential of your work...If thing goes well you can order specific part to be fabricate in china and just assemble a kit for international market! This design can be adapted to any 2.8L VM motori engine not just Liberty CRD....

Come on Mark THINK BIG! :mrgreen:

Problem with the new GC's is they are just as low to the ground and also independent front suspension just like the liberty. I wanted the GC for the solid axle which means I can lift it higher. I currently have a 6.5" long arm lift and 33" tires.

I have full confidence in the pushrod 4.7L HO V8 also. It is simple and reliable power, it has forged crank, STRONG V8.

In the long run i think it will be simpler and cheaper to maintain. It has a timing chain that is good for 2-300k miles, $20 thermostat, easy to access parts, cheap parts, no VH, no alternator coupling, no sooty MAP sensor, etc. Like I said, i miss the torque (I might add i miss the GDE hot tune torque) but I have much more HP (265), adequite torque (325), 6500lb towing capacity, and 0-60 is 6.9 sec flat.

Still a very fun daily driver. Towing may be not quite as effortless as with a turbo diesel, but everything else is a great package. A few interior pieces broken that don't change engine reliability doesn't bother me to fix once in awhile.

You have to do what you have to do, that is all.
Good luck to you, you have been fun to read and have contributed greatly..
My diesel weasel has been running so good I was thinking of buying another.

Mine is now reading just above the 1/4 mark like the pic with the Orange line. It's been lower and not rising as much since the GDE tune. I doubt that has everything to do with it so I guess I need a new t stat put me on the waiting list
