    It does; along with all DS OBDII units. You can alter the values but they have no effect.

    Another anomaly is the medium speed fan setting in either mode...does nothing.

    If I'm remembering correctly, old school T.S. for hwy speed run hot, [aside from collapsing lower hose], was a worn impeller on water pump...How many miles on it?

    I've also seen cars with the radiator clogged with cotton wood. Ac condenser had a little on it but radiator covered.

    Well now that I’m in the process of tearing down the entire top side of the engine I decided to boil the tstat. Opened all the way right at 190.

    Nothing I’ve done has solved the issue as of yet. Once I get the cam and top end all put back together and tune ill
    let you know the results.

    All the parts were worn (185000 miles) and just did it mostly as preventative. Yea I’m well aware of new parts fail, especially mopr, due to the fact that I’m a Chrysler service advisor. However, it’s not the t-stat. Did the boil test, more than incense, and it opened up all the way right at 180-190.

    Water pump was replaced and the original impeller had no wear.

    Radiator is new and has good flow.

    One last note, if the thermostat were the issue, wouldn’t it make sense that when I was running wirh NO thermostat that the problem would have disapated? Just a thought. I’m really beginning to suspect the radiator size just isn’t up to the job and maybe going to a fluiddyne 4 core. If that doesn’t do it, MOTHING will.

    Sounds lie a t-stat and if so you have some bad luck with them.
    I had one warning me the same as yours and eventually failed to open and got hot.

    They can loose the wax medium that expands and operated the opening motor. Here is a pic on the one that got me.

    There was road course discussion years ago about the flow rate within the cooling system being so high that without a T-stat installed, coolant would not linger long enough within the radiator to be cooled sufficiently.

    Hmm....interesting. Well once I get the top end all back together I’ll report anything out of sorts and go from there.

    Well this was an interesting thread and have learn a lot about our cooling systems. However I’ve found my issue a little too late lol. It was the heater core hose assembly near the firewall. It must’ve gotten sliced when reinstalling my heads or from my wiper blade assembly. I know it sounds far fetched but it happened. It jumped timing so I had to rebuild again.

    Damn! FYI, those "T" fittings back there are notorious for cracking with any kind of long milage or time on them.
