I chased a similar problem on my 440 with the same results. In the end I switched to a better distributor that could keep up with my engine and the heat problem disappeared.

Then one day while I was running the car in my garage and setting the carbs, it dawned on-that engine was just not hot! I checked the temp gauge, and it said very hot. As usual, whenever the temp was up, the oil pressure would drop . Someone suggested I replace the instrument voltage regulator. Once i did that, the temp came down and the oil pressure went up.

When new, the non-thermally activated type of clutch may spin the fan at something like 30% of water pump speed, but when they wear out they may spin at half that speed without it being apparent. They don't last forever. > Replacing it with a thermal one is the best way to go, but at least a new non-thermal one would be a smart move.

Frankly I'm really not looking forward to adding something more to my agenda, but I would rather not hear of cars not able to be driven for lack of a fan clutch. > > Is there further interest at this time? > > Keith Boonstra > > - > On 3/27/2013 10:48 AM, David Schwandt wrote: >> >> Sounds like it's time for a complete cooling system rehab. >> If the system has not been serviced in a while I'd suggest Flush/fill >> stat and hoses for starters. >> And also double check temp sender and guage w/a infrared thermometer >> to be sure they are registering correctly. >> I may be wrong here but I would think a non operating heat riser in >> the stuck closed position my play a part in overheating. >> >> Dave Schwandt >> >> -----Original Message----- >> From: Chrysler300@xxxxxxxxxxxxxxx >> <mailto:Chrysler300%40yahoogroups.com> >> [mailto:Chrysler300@xxxxxxxxxxxxxxx >> <mailto:Chrysler300%40yahoogroups.com>] On Behalf Of >> robert554@xxxxxxxxxxxxxx <mailto:robert554%40centurytel.net> >> Sent: Wednesday, March 27, 2013 9:40 AM >> To: chrysler300@xxxxxxxxxxxxxxx >> <mailto:chrysler300%40yahoogroups.com>; 'Carlton Schroeder'; Rich >> Barber >> Subject: RE: [Chrysler300] Member with an overheating problem with his >> K >> >> thank you rich barber for adding the word hose......... i had this >> problem years ago on my stock car . took an old mechanic to figure it >> out, he knew right off the bat what it was ... i have always listened >> to the old guys .. there the ones that know the most... if they dont >> pass the knowledge down we tend to struggle.... bob hayen >> >> Quoting Rich Barber : >> >> Good point, but needs the word “hose” added between “radiator” and >> “does”.
