    Defroster Ducts and Vents

    The fresh air vents are supplied by air coming thru the plenum in front of the windshield. Leaves, pine needles and other junk like water get in there and become trapped. http://www.forabodiesonly.com/mopar/showthread.php?t=134919&highlight=cowl+vents To clean them.... There are drain holes...

    Sounds like the rad is all gunked up! After it gets hot, run your hand all over the front of the rad to check for temp differences.

    Think my heater core is going bad?

    If only 1 heater hose is hot and the other one is cool, you have a plugged core. Take both hoses off at the engine end. Reverse flush it thru the cold hose a couple of times and see what comes out. As for the noise...pull the fan motor out and check for debris in front of the core. 40 years of...

    Biggest most massive 4 core rad for a 68 Barracuda?

    Just because a rad has 4 cores does not mean it is better than a 2 or 3 core. The tubes are smaller and the farther thru the air flows, the hotter the air gets and the less efficient the rad is. My 340 has a .508 cam, headers and A/C and I am running the original stock 26" rad, clutch fan and...

    Should you run a car without a thermostat?

    Lets clarify at least one thing about the opening and closing of a thermostat. It does not jump fully open or closed at it's designated temperature like a valve. It sorta oozes open and closed. And with no thermostat, the cool water coming back from the rad will have a better chance of...

    will upgrading from stock 22" radiator to stock 26" make any difference????????????

    Do you have a clutch fan on it ?? And if you do, is it working properly....like sounding like a B-17 when you take off after sitting at the drive-thru for a couple of minutes?

    will upgrading from stock 22" radiator to stock 26" make any difference????????????

    Well, you have about 80 more sq. inches of radiator surface exposed for cooling as well as about a quart and a half more water. And in old cooling systems, every little bit helps. If you use the A/C water pump pulley as oppossed to a non A/C pulley, your ratio on the water pump to crankshaft...

    Cooling problems on '71 Duster

    What engine? Stock or modified? Radiator size? What fan does it have? Does it have a fan shroud? What you have is a lack of air flow thru the radiator at low speed.

    Dart over heating???

    A few of you missed the key sentences. Not enuff airflow thru the rad at an idle or slow speeds running up a steep hill. Means not enough air flow thru rad. Even the biggest fan won't help if it is too far away from the rad. All it will do is draw air from between the rad and the fan. A...

    Mechanical Fan VS Electric Fan

    A lot of electical fans put a big strain on electrical systems that were not engineered/built for them.

    A/C Question...

    As far as install rates, it would be about 15-20% at most. It was a $325 option and also reguired 7.00x13 tires which were standard on a V8 but $12.85 on sixes. Seeing how a 273 4bbl engine package with power brakes and HD suspension was only $155, it was really expensive to have A/C...

    How do you tell for sure if fan is pusher, puller or both?

    On most of them, to change fan direction, just reverse the power leads.

    I give up

    Dustermaniac, The 98/99 5.9 rad is a 22x22 inch crossflow aluminium. Keeps my 98 Dak R/T cool no matter how hard I work it.

    I give up

    If you can hear the fan running--like a B-17 on a take-off roll-- you should check the radiator. Cool spots will indicate low flow which basically means it is plugged. A infrared thermomter will point a plugged radiator real quick.

    340 Water Pump questions, anyone using Flow Kooler?

    You definetely need a shroud !!!! Air takes the path of the least resistance. Without a shroud, usually the air at the ends of the fan blades will get pulled. And it does not go through the rad. With a shroud covering the end of the blades, all air being pulled has to come through the shroud and...

    ***6 Blade Water Pump vs 8 Blade??***

    There is the problem. Standard rad, standard water pump, no shroud, no clutch fan, etc. At an idle, you have low water flow and little air flow.
