Chry54 Posted April 25 Share Posted April 25 trying to solve my running hot issue on my 54 chrysler 265 engine. my question is can exhaust gases get into the cooling system with the engine running but the engine does not lose water? dennis Link to comment Share on other sites More sharing options...
JACK M Posted April 25 Share Posted April 25 I will say it could be possible. But not likely. Link to comment Share on other sites More sharing options...
28 Chrysler Posted April 25 Share Posted April 25 Head gasket could be leaking . 1 Link to comment Share on other sites More sharing options...
Bloo Posted April 25 Share Posted April 25 There is a tool you can get that uses a blue colored fluid to check for combustion gas in the cooling system. It is not a perfect test, but if a car fails this test, there is definitely combustion gas in the cooling system. If you happen to be in the US, you can buy/rent one of these tools at Oreilly or Autozone on their tool loaner program. You take the tool back when you are done for a full refund. The only out of pocket cost in the end is the bottle of blue colored fluid which you must buy outright. 1 Link to comment Share on other sites More sharing options...
Chry54 Posted April 27 Author Share Posted April 27 so it is possible but not lkely. i was guessing the head gasket as that was replaced about 4 years ago. my compression is 100# in all cylinders xcept # 4 which is about 75#. i did not have the head resurfaced at that time. is there a name for this tool to check for exhaust gas in the cooling system? i can ask at o'reillys this weekend. thanks, dennis Link to comment Share on other sites More sharing options...
Bloo Posted April 27 Share Posted April 27 "Block Tester" or "Combustion Leak Detector". It usually looks about like this. Have you ever inspected or changed your water distribution tube? Link to comment Share on other sites More sharing options...
Chry54 Posted May 2 Author Share Posted May 2 rented that tool and the cooling system has no exhaust gas in it. the car has a new dist. tube. i bought a shroud and i am looking for a 6 blade fan.no luck so far. they were used on alot of 50's mopars and trucks. don't know why it is so hard to find. dennis 1 Link to comment Share on other sites More sharing options...
Bloo Posted May 2 Share Posted May 2 Is it getting hot mostly at idle or at speed? Link to comment Share on other sites More sharing options...
Chry54 Posted May 3 Author Share Posted May 3 at idle.will run coolest at about 45 mph, and then hotter at 60 and above.stop and go on hot days is the worst.. Dennis 1 Link to comment Share on other sites More sharing options...
Bloo Posted May 3 Share Posted May 3 Be sure that your timing is set right at idle and that it advances. The block might be full of sludge. You might need to knock the core plugs out and clean out the water jackets. @keithb7 posted pictures of an engine about like yours recently that had an unbelievable amount of sludge in there. The radiator might be clogged. If you disturb things by cleaning out the water jackets, I would suggest you add "Grimy's Sock" to the upper hose to catch anything you weren't able to flush out, so it doesn't just float up and clog the radiator. The big fan will help at idle and in parades. At speed it will probably do more harm than good, though it should be OK to run. The same goes for the shroud. For issues at speed, look over the front of the car for missing shields, pans, rubber flaps, etc. The air that comes through the grille should have no easy way to get to the engine compartment without going through the radiator first.

Dennis It appears to be how these cars of this era run when it comes to cooling. 54 Buick 264 nailhead. Idle runs warm. Stop and go runs very warm. What is specific issue?

Chry54 Posted May 4 Author Share Posted May 4 i have pulled the core plugs and flushed. i think there are areas you cannot get to this way. the rad is recored and clean.other people have said a shroud and a 6 blade fan has helped considerably. an essy project if and when i find a fan. just want the car to be driven in the NC heat. thanks, dennis Link to comment Share on other sites More sharing options...

Chry54 Posted May 7 Author Share Posted May 7 running at around 180 at idle in the garage when warmed up. temp guage right in the middle. at the top of the guage runs at around 200. maybe i need a higher capacity rad. current one is the original, but recored. it is a 3 row. maybe i need a 4? dennis Link to comment Share on other sites More sharing options...

My 54 has exactly the same cooling characteristics as your Chrysler. Never boils over in the hottest of summer days.

Chry54 Posted Tuesday at 07:14 PM Author Share Posted Tuesday at 07:14 PM does a 4 row make a difference? maybe it won't fit? dennis Link to comment Share on other sites More sharing options...
Bloo Posted Wednesday at 08:15 AM Share Posted Wednesday at 08:15 AM It makes a difference, but not much. Mostly it adds water capacity. The air is already pretty warm by the time it gets to the fourth row. Link to comment Share on other sites More sharing options...
