What do most of the drivers do to prevent overheating in a very very slow parade with lots of waiting behind bands etc...
Under normal cruising I don't have a problem, but tomorrow worries me a bit
If you have a good radiator no problem. If you have a bad radiator removing the hood won't help.
Just like Royce said.
The T's I've seen in parades haven't had their hood removed. It all comes back around to the radiator when it comes to cooling.
The radiator on your car looks like its a new radiator in your profile picture. You shouldn't have any problem.
In stead of driving in a straight line, we drive our cars around each other so the cars keep moving. I think the crowd likes it as well. Go slow and don't run over the crowd.
Test it out idling and driving really slow down a back street or empty parking lot a week or two before the parade. A real life experiment will tell you the answer.....
I think if your radiator is working correctly you would be fine. Tim
Run the throttle at a fast idle. Go with the hand brake half back and advance ahead using foot on low band. The advice above applies mostly to 17 and later cars, they forget your radiator is a lot smaller than the later T'so. Put some Water Wetter in the radiator, it really does help.
On an air-cooled engine, it's important to keep the hood closed so the baffling can direct the flow of air where it's supposed to go, but when it comes to a liquid cooled engine, once the air gets through the radiator and picks up its heat, you might as well let it out. _Hot air rises, so when you open or remove your hood, some hot air will go up and out and the engine itself will be able transfer some of its heat to the now cooler air around it through radiation—to an extent. _Opening up the hood may not help very much, but it couldn't hurt.
Two other things you can do to enhance cooling are: Enrich the mixture as much as the engine will take without running badly and advance the timing to the same degree. _Retarded timing or a lean mixture WILL cause your engine to run hotter, so do the opposite. _Obviously, start your day with the radiator filled to the tippy top (and just let the system blow out the excess).
Carry a bottle of water with a spray head and mist the radiator when it starts to get hot.
You will be surprised at how quickly the temp drops.
I posted my question too late to look at all the responses. Made it thru the parade with only one boil over at block 4! Seems the parade directors don't realize it is important to put us up front so we can move at a faster pace than the band that stops to play a tune...or 3!
Northern MN has never seen Mardi Gras beads before so it was a big treat over tons of candy...everyone loves a vintage T...only the guys knew the rules and flashed the young lady riding with me...I really enjoy sharing with others my excitement of owning a 1915 Brass Roadster...however, it will be the 600 hp 69 Mach 1 at the show tomorrow night.
How would your Mach 1 handle a parade like that? ;-) NOT the point at all.
Would you tell about your throttle and timing settings during the parade with your T?
I am truly interested.
When I paraded my crappy little Ford a bit south of you (ten years ago in Central MN), I actually ran it with both ears up most of the time and only pushed the pedal when needed. Never had a boil. But I do have a non Ford fan......
Granted, I have a wheel chock (water pump-it was all I had) under the hood but with a rad coated with silicone and acrylic latex caulk keeping the water in, that has been given the baking soda treatment and a very original '19 engine (wore out).
Greg, those beads caused quite a stir didn't they? Good fun!
A bottle of water with spay will do nothing. You could use the water in the bottle to refill your T after it cools off a bit.
This is what I found yesterday. We started up the engines and drove to where the parade would start. Mine was idling for about 10 minutes and the motometer was about half way up (below the circle). We didn't start moving, so I turned off the engine and we waited about 5 minutes more. By then the motometer was almost to the top. We started up again and drive the two mile parade route. The wind was from the side, so not much direct air into the radiator except what the fan provided. For the entire route the motometer was about "normal summer temperature" After the parade we went down the strand to Imperial Beach and it dropped to about half way up again.
So, I should have turned off the engine until we were ready to go. Or left it idling. Turning it off for 5 minutes actually caused the heat to rise because no air circulation.
The water temp showing at the moto meter goes up when the engine is shut off, normal. Sounds like you did jut fine. My take on keeping the hood closed, the fan has a better chance of blowing the air over the WHOLE engine not just the front and out the sides might even be better with the pans installed. Even at idle my fan seems to move a good amount of air.
This guy obviously thought it would help, though he is towing a wagon.
I did the big local 4th of July parade for one of my local towns. Lasted a little over and hour start to finish with temps in the low-80's. The car was fine and motometer barely touched the lower third of the circle. But it was a little toasty driving the thing for me with all that heat heading back into the driver's compartment. My biggest challenges on the day were staying vigilant so I didn't run over any kids diving for candy, and avoiding skewering the Boy Scouts marching in close order drill ahead of me with the starting crank. All told; lots of fun though.
"My biggest challenges on the day were staying vigilant so I didn't run over any kids diving for candy"
Interesting to see that mentioned. This is precisely why I won't do parades. I witnessed a near-miss once and that spoiled it for me. Throwing candy in the street is a foolish practice.
Before the parade I did top off the cooking system so expected a coolant loss at some point...with no water pump it stays hot most of the idle time. I did keep the idle a bit higher than normal to move air with the fan. The timing was advanced half or better, I just listened to the engine!
When we got out of the car, we left a puddle of sweat on the seat...whew
If you ever decide to drive in a parade without a hood, be sure to inspect your fan for cracks before! If your fan decides to toss a blade, the hood keeps it contained. (Don't ask me how I know this, and it was in a parade) No hood with a crowd of people lining both sides of the street would not be pretty if a fan blade were to let go. I can imagine the headlines now...
Sorry if this comes across as "The sky is falling", but....
