Troubleshooting temp issue

Troubleshooting temp issue - 12/06/13 01:09 AM

mild 360 in my '71 Dart with a 26" radiator (with shroud and flex fan) is running hot... takes about 20 minutes of driving but it gets up to about 235 degrees (even when it's 35 degrees out).. I tried a new radiator cap - same problem...

What's the most effective way for me to troubleshoot to determine whether there's a blockage in the radiator or in the block - or if there's something else going on?

If it's the radiator, I'm just gonna buy one of the Champion aluminum units sold here by a member for less than $200 delivered.. I just want to make sure that's the issue before I drop another $200

When your car gets to 235 does it boil over?
Buy the cap that was suggested to you about two weeks ago that tells you the temp. right on it to determine if it's a gauge issue.
Or at the very least when it's 235 can you with it running slowly open the cap to see what's going on in there and/or use a meat type thermometer.

I'm assuming the timing is in the ballpark & the mixture is also (no vac leak). Is that stoplight to stoplight driving? If you take it out on the highway what does the temp do? I'd maybe shoot it with an IR gun to confirm what the temp actually is & my first step would be to toss the stat for a day which wont hurt things. What's the history of the radiator? You mentioned the cap, is it loosing coolant?

If you just want to make some random guess. I'd start with the radiator. They age and clog up with build up.

Not often is there problems with the block.

Does it get hot while idling or how about coasting down a hill in neutral, will it pull the temp down?

Please don't buy a new radiator yet.

First get rid of the flex fan, it won't work and it won't last.

IMO Run a real mopar fan, I use the "216" fan, but there is another MP fan sold that works way better than any flex fan.

Please start there.

Check the initial and total timing and repor back! Is the vacu advance connected?

Re: Troubleshooting temp issue - 12/06/13 03:00 AM

'Hot while idling'??? First...

What do you know about the condition of that block???

Coolant passages clear???


Have a rad shop check-out yer rad if in doubt...

OEM rad works just fine, and is my first choice...

Get rid of the flex-find a 7-blade A/C fan...

Re: Troubleshooting temp issue - 12/06/13 06:46 AM

sorry guys.. I misreported on the type of fan... it's an OEM fan .. and it's in the shroud, so it should be pulling plenty of air through.

Timing is set and no vacuum leaks.. I resolved those issues last year when I was trying to get it running right

Re: Troubleshooting temp issue - 12/06/13 03:53 PM

Then it's lean, most old motors are today because of the ethanol gas. Jet it up, I bet you it will help.

You sure the timing is correct?

OK good so we know it's a real # then.

Does it get to that # just with time or time and cruising?
What I'm getting at is it a stuck in traffic (low airflow) problem or cruising problem too?

Top and bottom of radiator same temp?
Pull thermostat to see what temp. it is and or replace with 180 or 160.
Could belt be loose and slipping?
Lastly is there a spring in lower hose?

Re: Troubleshooting temp issue - 12/06/13 09:35 PM

Some suggestions Make sure you are running a 8 blade water pump and no more then 35-40% antifreeze. Get a Mopar rad if possible they are expensive but worth it. Be sure there is no exhaust restictions IE Mice nests etc from all the sitting Also the thermostat I pulled a broken one out of a car last week first one in decades If you are using aftermarket AFB design it is too lean, do yourself a favor and get a older Carter AVS or a Holley

Re: Troubleshooting temp issue - 12/07/13 03:29 AM

what temp t-stat?
Got access to a thermal heat gun?
How hot is the bottom tank compared the the top? Are the cores of the radiator hot all the way across?
Does the temp go down if you turn the interior heat on high? (heater core is just a small radiator).
When at 230 does the air the fan is pulling while the engine running feel hot?

I feel that even if your timing was off, that at 35-45 degrees ambient there should be enough heat exchange for it to run normal "IF" the radiator is flowing.

What's the condition of the coolant?
Has it ever been brown/rusty?

Not sure how it is up there, but finding a radiator shop is near to impossible anymore.

Re: Troubleshooting temp issue - 12/07/13 05:04 AM

OK... so I know that reading spark plugs can help see how the engine is running.. so I took a few photos of one of the plugs today.. this is after driving it home from work last night, and no running today.

Re: Troubleshooting temp issue - 12/07/13 05:07 AM

Tomorrow I'll do some further checking and temp measurements per your advice (bottom of radiator versus top, checking the lower hose (I did put a spring in it last year when I realized it was collapsing when it ran), and I may just pull the thermostat out to see how warm it runs without one for a bit...

And to answer the question about how I was driving it.. I was doing about 50mph on long open stretches, with outside air around 35 degrees F.

Re: Troubleshooting temp issue - 12/07/13 05:31 AM

Just checked timing.. about 25 degrees advance at idle, and 42 at about 2800-3000 rpm
Posted By: Pacnorthcuda

Re: Troubleshooting temp issue - 12/07/13 06:01 AM

Your timing numbers are high. Back them off to 18 at idle, which will net you 35 total, which is much more reasonable. Don't know if that will help the overheating much though. :twocents

I am assuming we are talking about mechanical advance only.........and now that I think about it I think my assumption is wrong.......

Re: Troubleshooting temp issue - 12/07/13 07:11 AM

Posted By: cal_gecko

Re: Troubleshooting temp issue - 12/07/13 09:10 AM

realized that when I was checking timing, I didn't disconnect the vacuum advance from the distributor.

I'll do some research on how to make the mixture richer on the carb (Edelbrock Performer 600cfm)

Which sucks, because the car's getting 8 mpg as it is.. I'm guessing if I go richer, it'll get worse!

Why do you have vacuum advance at idle?

LEan misfire can cause poor mileage too.

Re: Troubleshooting temp issue - 12/07/13 02:51 PM

If its overheating at 35 F with decent fan something is seriously out of whack.

As a useful and low cost diagnostic, suggest you remove the T stat and run it. As mentioned above, run it with the cap off for a while and watch for coolant flow in the top tank.

If removing the stat improves temps it is a bad stat. If you don't see coolant flow either the radiator is seriously blocked or the water pump is fubar. Its rare, but the blades can rust off the pump.

If you suspect the radiator, you can pull it and get it checked out at a rad shop.

Also, mild "at home" flush of the block and radiator wouldn't hurt. I rig up an adapter to go from garden hose to radiator hose. 1 1/4" or 1 1/2" PVC pipe matches rad hose diameter pretty well. With stat removed, rig it up to flush the block or radiator.

Is it a clutch type or a direct blade? Also I believe you want the blades of the fan to sit about 3/4 of the way into the shroud...is that where yours are

I'll pull the thermostat out today (crap, I don't know if I have any gaskets sitting around... might have to run to the store to get one) and test that...

for reference, here's a top view of the rad/fan/shround.. it's a fixed blade fan.

Re: Troubleshooting temp issue - 12/07/13 05:30 PM

It appears that the fan needs to be spaced farther into the shroud which is needed at lower speeds but is a non issue for it to be overheating at 50MPH. Something else is going on

I'm suspecting a blockage in the radiator. I'll check the thermostat today.. and if that doesn't work, I'll disconnect the hoses on the radiator, and see if I can run water through it with the garden hose. I guess that should tell me if there's a blockage.

It does sound like I may be running lean too .. which is surprising because the exhaust is pretty pungent .. but I'll need to look up how to richen the mixture on the Edelbrock carb.

Actually a lean misfire can make it smell gassy as the mixture does not ignite in that cyl or random cyls & goes out the tailpipe. Take off the metering rod caps & remove the metering rod piston/rod assys & put something under the spring(s) to block them up then replace the assys & take her out for a spin & you'll be on the "power" step which is way richer

I'll take a look and see if I can visualize what you're talking about a bit better. Not sure what "something" would be that would be appropriate to put under the springs to block them up .. .i'll see ..

Re: Troubleshooting temp issue - 12/07/13 07:58 PM

Yes I would push that Fan in another 1/2 inch also but not the problem you are describing.

Question is that a 2 row radiator or 3??

Remove the rad from the car. Put the old cap on it. pour some muratic acid in the rad. Plug the inlet/outlet holes and slosh it around in all directions. That crud will come out in a few minits. Rinse it out with fresh water and reinstall and fill with coolant..

It would actually be easier to just get a rod the same diameter as the spring and make it the proper length to put the rod in the upright position (and still be able to put the cap on). Don't force the metering rods as sometimes they need to be gently rocked into the hole in the jet.

Also, check out this link ( http://vb.foureyedpride.com/archive/index.php/t-74438.html ) for your tuning woes. He had some logical points so I tried it and the difference was amazing. To sum it up, the 1406 is way lean out of the box. Its the same carb as the manual choke 1405 which is known as performace carb, while the electric choke 1406 is known as an economy carb. Why? the stock 1406 is jetted something crazy like 4 steps lean when compared to the stock jets on the 1405. Even when you rich on the 1406 chart, you are still waaaayyyyy lean on the 1405 chart. The answer was to completely toss the 1406 tuning chart and use the 1405 tuning chart and base settings instead. Take a tuning kit for the 1405 and set the 1406 for the stock setting of the 1405. Then tune from there.

PS: the extremely lean carb will smell just as fuely as an overly rich one. Following the suggestions on that page made my car run/idle 1000% better.

Ordered a new Champion Aluminum radiator from a member here who sells them. I'll pull the current radiator out of the car and swap it as soon as I can!! hopefully the trans cooler lines line up properly, and I can move my B&M tranny cooler over to the new radiator without any problems.. while I've got the old radiator out, I'll be sure to run a hose into the block and rinse out any crud that may be in there..

I do have a couple parts carbs (same model) out in the garage.. I"m gonna check to see if either of them have the richer metering rods ..

Mark that should have been easy to figure out with an infared heat gun...the radiator temp should have been a lot cooler in the area where veins were blocked. Be sure that you have the correct type cap for a non-recovery coolant system...or do you have a recovery tank/system on that?

I can get a new aluminum radiator delivered to me for $180... I'd rather do than and not have to worry about it. I'm sure getting mine boiled out would probably be at least $125-$150 .. and it would still be old and ugly. .. might as well just get a new one and be done with it

I totally agree, someone's on the rag today. Cal you're fine & get a new Champion in there & you're set




No worries.. I appreciate the assistance, and there's always one person who likes to make themselves feel better by putting someone else down. With the high I'm on from getting this car on the road, he'd have to say a lot more than that to get under my skin

Thanks guys!!! I'll look into the metering rod set too ..









im not putting you down.geez,lets see.
im driving down the road and my car dies

Forever in debt to your priceless advice.

Installed a new 26" 2 row Champion aluminum radiator today... couldn't use the factory shroud that I was using on my existing 26" radiator.. .put in a 160 degree thermostat... went right up to 165 degrees the whole time I drove it around.. sitting at a couple long stoplights, it went up to 180, but as soon as I moved, it went back to 165.

For best performance and engine wear you need to go to at least a 180* stat.

Not,, optimum efficiency is achieved at the higher temp. most had 180/185 from the factory..

X3 on the 180 or higher stat. 160 would be the proper piece for 1/4 mile drag racing only
