I would be curious what the IR temp reading is on the top of the tstat housing, which should be close to block temp, but would agree that this information suggests a bad temp sending unit. PN 05066779AA I believe and should not cost much even on your side of the pond. The only hard part of replacing it would be releasing the wiring if, as was my case, the release tab happens to be on the bottom - on reinstall be sure tab winds up on top.


Sorry , what do mean by tstat housing ?
Thanks for the part nbr. I was looking for one this pm, and got lost in the numbers of PN.
I order most of my parts from the us, even with USPS costs, it is cheaper than here. Even got my Frankenlift from the mail.... :D

You are right, by trans oil cooler , I mean the by-pass cooler for the trans fluid that I have mounted myself. My stock cooler below the condensor died 2 years ago.
Could it be that the cooler is too small? I am thinking of mounting 2 Delare cooling fans on it....

I have replaced the CTS by a new one. No particular sigh of corrosion or dirt on the old one.
I will make some heating tests today and post back.

DOC



can you be more specific on the procedure to check the residual pressure after an overnight cooling down ?
i don't know what to do and to check... :oops:
thanks

Note:sorry to tbentzen for highjacking his thread, but i hope it s ok as we are having exactly the same problem on a same 2005 CRD


This is how I check mine, if there is pressure, you most likely have a head gasket leak.

Thanks Filman
I have made the test for leaking head gasket. Opened slowly the coolant tank with engine totally cold, absolutely no pressure or bubbles, no psheeet !
So I guess I am safe on this side.

I made a heating test on the same uphill road after having replaced the CTS , the needle was getting close the red at the end of the hill......

Next is the fan ( and next one is a brand new JK.... :wink: )
I have received a 11 blade fan in nylon, 52079654AE, and a Hayden 9205 should arrive today.
Still have to find a way to get a Schley 10800 tool shipped to me for cheaper than 50$....
Any Good Samaritan on your side of the pound ? :D

Topan, what exactly do you need? Shipping for less than 50, or the part and shipping for less than 50? If you only need a wrench to stop the fan pulley to turn when you want to take the fan out, you can do that with a socket, I think is a metric 13, you insert it in one of the holes in the pulley where the bolt gets in the engine and secures the lower side of the pulley in the engine. You may need to move the pulley till the hole aligns with the bolt.

Well, see what you can do without any tool, I can see how much the shipping would cost from here to you, you can also quote yourself on USPS website (usps.com), I think you'll be fine with a socket though, plus you'd be saving some money for sure.

Topan you do not need an "special" tools to remove the fan. Steps as follows:
1. go to http://www.beesvillebeefarm.com/jeep.html and scroll down to image 16 if I counted right. You can use the allen key trick as illustrated or better yet a regular 13mm jammed against the bolt head or 1/2" long socket on the bolt head. I've done both but prefer the latter as it's easier to hold the socket in place using a ratchet handle than to hold the allen key. This holds the thing that the fan screws onto in place while loosening the fan nut.
2. while holding the base (helps to have a helper as this is really a 3 hand job although you can do it with 2) slide a 36mm wrench (big crescent wrench will do - you might call this a spanner) onto the nut and runscrew it in a counterclockwise (as facing the front of the engine) direction. Nut may be on there really tight requiring a persuader of some type (small sledgehammer works) on the wrench in the unscrew direction to get things moving.
3. once the fan nut is broken loose do not fully unscrew the fan. Rather unbolt the fan shroud (2 bolts part way down the outer edge - 1 on each side. Be careful not to misplace those bolts as length is critical and don't lose the nuts that are poorly captured in plastic retainers on the radiator; I zip tied my nuts in place to prevent future loss). Unclip the lines across the top of the fan shroud.
4. place a piece of cardboard or a towel between the fan and the radiator to prevent radiator damage.
5. unscrew fan.
6. carefully work the fan and fan shroud out as one "package". NOTE as I recall you have to tilt the fan shroud a bit left then right or perhaps the reverse, it's obvious, to clear the radiator/cac hoses.
7. before reinstalling I'd recommend you cut the bottom 1/2 of the fan shroud off just below the tabs for the mounting bolts. That doesn't reduce cooling any and makes future work much easier as you can remove the fan and fan shroud as 3 separate units. Otherwise reinstall is the reverse. No need to snug the fan nut down really tight as the direction of spin is such that it will self tighten although geordi indicates a bit of tightening is wise.

sorry for the late feed back
Thanks papaindigo for the instructions to replace the fan. I have printed them out.

I was in vacation: road trip to Croatia (really beautifull by the way !). We crossed Italy by 32 celsius with all windows down, and with heater and vent to the max to take out some heat from the engine.... :pepper: :JEEPIN: :pepper:

I am doing the following to address the over heating problem:
I have received a few parts:
-nylon fan
-Hayden clutch 2905
and am still waiting to recieve the Condensor and TOC (stock). i looked closely at the condensor and on top of being very dirty, the small soft "fins" are all crushed flat. It must be coming from tree leaves and branches that went into the fan when doing off road.
the results is that the condensor seems to let go much less air through itself.
i will also finally replace the trans oil by some good ATF4+
and will also replace the trans filter and grid (don't know the name in english sorry) that also serves as filter.
Summary i will replace:
-the fan
-the clutch
-the condensor
-the TOC
-the Trans Oil
-the Trans filters

will keep you guys posted on the result...

Topan - if a significant number of the fins on the condenser are flattened then it''s likely that's a large part of you overheating problem simply because or lack of air flow thru the condenser and on thru the radiator and intercooler. I'd also expect rather poor air conditioner performance. FYI if you are patient you can use a small flat blade screwdriver to straighten out the fins. In fact just Google "straighten ac condenser fins" and you will find instructions not to mention special fin straightening tools.

There are some tools that look like a hair comb, but for very bent/flatten fins that won't work. There are also "special" Ac tools that have some thin steel pins on the "comb" and you can also adjust the length of those (I. E. protrusion) , but best is patience and a pocket screwdriver, I believe it would still take less time than replacing the condenser, recharging the Ac, etc.

Thanks for the tips guys.
The condensor, on top of being damaged, is full of dirt.
The TOC is perforated and despite the bypass cooler I installed, my trans is overheating as well.
As I found a relatively cheap TOC/condensor (340$) incl. shipment , I decided to buy it.
I had too many birds to kill at once.
I will replace the TOC/condensor.

Hope my overheating problems will disappear.
Will keep you posted

Here we go, I spent my Saturday at the garage of a friend.
I replaced the following parts , it took me 8 hours, but I was alone all the time.....

1. Replaced the original fan and clutch with the 12 blade nylon fan of Grand Cherokees and Hayden Heavy Duty.
The removal was easy, thanks to the instructions given by Papaidingo.
Image

I managed to make the swap by lifting slightly the plastic shroud.
Hope you appreciate the fine piece of technology that keeps the hood up, an umbrella, yes, but a Jeep branded umbrella :D
Image
I remove the front engine guard (chromed plastic) and unbolt the top part of the black engine guard.


2. The condensor/TOC was really in bad shape, the TOC was a pack of oil, and the condensor ' s blades we're flatten by fan. Plus the whole thing was stuck with dirt and dry mud.

3. As the turbo cooler was very dirty, I removed it as we'll to allow a good cleaning with a water hose.
Look a bit the dirt that is stopping totally the air to go through.

Image
Image

4. Finally replaced the condensor/TOC with a new one.
Image
I decided to assemble the Condensor/TOC and the turbo cooler prior to mounting back in place. This made the mounting easier I feel.

5. I replace the trans fluid with some good ATF4+ , replaced the filters (cylinder and flat)

Here it is. The tests I made so far showed no sign of overheating.
So I guess my problem is solved. :D
