Title: I'm feeling hosed.....
Post by: R. Dave Carr on May 20, 2008, 10:20:12 AM
Guys, I have the radiator out of the 300 for service, and leak repair.  I found that the lower radiator outlet had a rubber sleeve on it to make a larger sized hose fit.  The hose that came off is the same size on both ends.  Should my radiator outlet be smaller than the water pump outlet where the hose attaches?

No, the OD should be about the same.  I think it's 1 1/2"
 
I've seen those sleeves from K-Mart hoses.

Spoke with radiator guru, he says he will see if he can get proper outlet on radiator for me.  Also told me many of the tubes at the header plate were weeping, so ALL will need to be re-soldered.   Otherwise a re-core would be about 380 bucks!  So, for 90-125 my radiator will be made good again.

Why Steve?  The radiator is not rotten by any means, just has some bad solder joints, and a wrong sized neck.   Apparently it's a newer aftermarket radiator.

OK  I was assuming it was the original

Ah, the aftermarket explains the wrong size outlet.

That guy will be chasing leaks forever.....my buddy the radiator guy says any tube leaks at the header are a sign the rad is trash. Even the big truck cores are a waste of time when header leaks appear. I have spent some time standing next to him helping by holding a droplight for him and listening to the profanity fly as he tried to quell tube leaks.....this is why you don't hear of "rodding" out radiators to clean them anymore. All of the heat needed to remove the tanks ruins the factory solder job between the headers and the tubes.....go with new and get a lifetime warranty rad while you're at it(http://www.moparfins.com/forum/smileys/smiley20.gif)

My rad guy has been doing radiators for over 30 years.   He's confident that the repairs are all it needs.  If it needs a radiator later on I can do it, but I want to try what he reccomends first.   Especially since were talking several hundred dollars!

Since your talking rad's I have a question. (Suprise)  When the engine is running should the hose coming from the top of the engine back to the radiator when squeezed give or have pressure in it and not give?

If the stat is open, it should have pressure.

Ok I just searched the net with no luck.   What's the stat?

The thermostat.

Doh! (http://www.moparfins.com/forum/smileys/smiley5.gif)  I look in my tech manual tonight and see where that is and check it.  If I recall correctly it located in the back, firewall,  on top of the engine near the carb.

Actually it's at the front of the engine.  The upper radiator hose attaches to it's housing.

Shazam!  The heck you say.     Well  gooolly I didn't recall correctly.   So what's the thing poking up in the back with the wire leading out of it to the firewall? 
Title: I'm feeling hosed.....
Post by: Steve on May 21, 2008, 11:35:59 AM
Oil Pressure sending unit.  The one with the two wires in the watter pump housing is the Hot/Cold light.  The T Stat is next to it where the Rad Hose slops on.  It's held in with two bolts.
 
The hose should get hard when it's hot.  (MMMMM  Did that come out right? (http://www.moparfins.com/forum/smileys/smiley36.gif) )  If not, it may be a couple of things.  Rad Cap bad or loose, or as mentioned, a bad T Stat

Now that was funny.
 
So if this is not working right should the temp light come on?  
 
I read the tech manual and it appears the temp guage is working correctly. When I go to start the engine the red light pops on for a second then off as the manual says it should, then the green cold light till it heats up.  Hot never comes on.
 
It looks like a pretty simple repair, new gasket and stat.

Only if your motor overheats, or is getting close to doing so.  A soft hose after a 15 minute running period indicates a problem.  As Steve said, could be a stuck thermostat or a bad cap, or it can indicate a leak somewhere.  If there is a problem, and you take your car on an hour-long drive on the freeway, that light will come on when you come to your first stop.  Or, it will come on if it's a really hot day and you're using your AC.  The best way to know your temp is to install an after-market guage.
