cooling system issue after dealer work on timing belt & waterpump.

Hi I have a 2005 CRD with 111000 miles on it. I did the GDE eco tune a long time ago. I never had a over heating problem until now. I made the mistake of taking my jeep to the dealer to change timing belt,waterpump & new hoses. I took it on 3 hour trip to the shore a few days after I got it back. @ hourd into trip I smelled antifreeze & gage read almost to H. I was running AC as well. I stopped & looked at engine electric fan not running & hydrolic fan was on. I let it cool off & went on my way. The temp. gage gradually rose to 3/4 and I turned AC off. I checked fANS & electric was off &hydraulic was on. After a bit temp gage went to 1/2. I checked both fans & they were on. I decided to run AC and gage held at 1/2. On the trip home the same thing happened on & off. I took it to dealer. The first day they had it local temp was in low 70,s. They said they ran it for hours & drove it with gage not going more than 1-2 notches towards hot. They said they checked every thing else. I explained to them that the problem was electric fan. They make have nicked or pinched one of wires to fan or controller. I also tested the fan & hi & lo controllers before hand. They didn't listen to me. I made they keep it another day. It was in the 80s today& I got a call saying they saw it running hot but not boiling over. They called me later & said bad fan clutch ?

Is it possible the tech damaged fan clutch when he removed or reinstalled it to replace timing belt. It is clear to me that he could have caused a short in the electric fan wiring. The service manager is not acknowledging that there is an issue with the electric fan wiring.
Has anyone had a problem after dealer timing belt job?

I'm not terribly familiar with the CRD but based on your description and the dealer's diagnosis something is backwards...

You indicate the mechanical fan was spinning but the electric fan was not. The dealer says the fan clutch (which starts/stops the mech fan) is bad, which has nothing to do with the electric fan.

"Suggest" to them that you want the tech to do a diagnostic on the electric fan to insure it is operating properly. One other thing that is an issue with the gasser: Make sure the thermostat is installed in the proper direction. It is common for the gasser thermostat to be installed backwards; when installed this way it closes when the coolant gets hotter. Maybe an issue with your CRD...?

My 2 cents.
