  • The Cooling System.

    As some of you might know or have figured, I have been doing extensive work to my cooling system to get it into an optimal performance situation.

    Well, the question came up if was I using antifreeze? Well, I haven't been, and since to clean my filter I need to drain a gallon off the top, I figured it's easier and much cheaper to run water and some rust inhibitor. We all know the problems with trying to recover anything coming from that little petcock on the lower hose/pipe.

    Since I want to install another temp gauge at the inlet this means way more than a gallon of water off the top.

    So today I have had another brain fart and am going to try to fix the situation by removing the petcock and soldering on a short length of tubing that I can slip a rubber hose on to recover the coolant. since there is no "seal" to speak of, I think with a minimum of heat this can be done easily, as long as I take it apart first so I don't release the spring from the spring.

    Pictures to follow providing I can use the "edit" feature to add the pictures. I haven't tried this yet. Wish me skill, 'cause if it wasn't for bad luck, I wouldn't have no luck at all!

    I just had trouble with the edit when trying to add a picture I forgot. I copied the post, deleted, and then did it over. Let us know if you figure it out . Pat

      Recruiter, I don't see engine pans, some say the pans help in cooling

        Well, about the engine pans. Well, that is a not so funny story,

        See, the car didn't come with any, I suspect lost in time somewhere in Michigan.

        Anyway, I found some on fleabay that looked like the correct ones for my time frame and purchased them quick like. After waiting 3 weeks for them to come from Georgia, I contacted the seller to find he did not have any, but had them ordered from a vendor or some such. Well, needless to say I canceled the order and got my payment back, but alas, I have looked but found none to my liking or time period. So, until something turns up, I will keep an eye open and wait.

        As for improved cooling, I really can't see, using common sense, how directing the airflow at the floorboards will help the air circulation. To my thinking, it would actually hinder the free flow of air in and around the engine from the fan.

        I know there has been a multitude of discussion about this throughout the years, but frankly, I'm not sold.

        Think about this, how many moderns have a fan shroud today? Nearly all of them I'd say. Now if it didn't help air circulation and flow, why, and since we know it helps, why did Henry stop putting them on?

          Not wanting to argue and I've wondered how pans would help aid in cooling. The only thing I can come up with, helping streamline the air flow out of the radiator. The air coming back under the car and maybe swirling up and disturbing the airflow out of the radiator. Ps I haven't put mine back on,yet! Good luck finding the pans you need!


          • #6
            I haven't noticed that the pans keep my A's cooler, but they do look good and are supposed to be part of the grounding system.


            • #7
              Does anyone have a connection for a wind tunnel test? With the appropriate sensors in place it can be determined if the engine pans enhance the funneling effect of the air down the sides of the motor and trans area. My own non scientific observations using a thermal imager suggests that the pans do enhance the cooling compared to not having the pans installed. Without the pans much of the air is lost out the bottom
              As far as the grounding yes anything connected between the frame and the engine will enhance this but there are many more ground points in these cars than most folks realize.
              my 2.5 cents


              • #8
                the pans should help funnel the air thru the radiator and thru the hood side vents which help to create a bit of a fan shroud.

                  With no engine pans I don't understand the need to put an extension tube on the petcock??

                    X2.. even with pans the coolant will drain off the rear of the pan into a stream

                • #10
                  Oh, the reason for the extension for the petcock is so I can attach a hose to it and drain into a bottle instead of the tub, which I would have to clean before and after to use the same tub for oil changes and what-not. This way, the tub can just be used for the garbage off the bottom of the engine.

                    Evans Coolant revisited
                    by Eric
                    Greetings everyone.

                    While I want to get more experience with my new Evans Coolant, I thought I might share what I've found so far. Today I ran my 31 coupe about 25+ miles, or so, and was part of a parade of cars through Seal Beach Leisure World. Fun time !!! Today's air temperature was 75° F. I found that my engine temperature was indeed higher than what I've experienced with plain-Jane...

                    by Bill G
                    See the attached photo. This was taken a couple months ago when it was still colder outside and I would go out to the garage every week or so during the winter and start the car up for a while or even take it for a few mile drive. Since then I cleaned it out, but now after about 100 miles and warmer weather, it is forming again. Weather now is in the upper '70's to low '80's

                    Engine pans, yes or no?
                    by Curly
                    I haven’t been running engine pans. I got a set recently thinking I wanted to add them. After dry fitting them I’m wondering if I even want them on.
                    1. Keep engine cleaner.
                    2. Engine cooling, although I haven’t heard any conclusive evidence this is factual.
                    3. Electrical ground, but this is not an issue for me.

                    Do you run them? Why?

                    Over heating only sometimes
                    by Greynomad
                    Last time I drove my ute any real distance, it overheated and boiled. I blamed a dodgey thermostat so I removed it. The trip home (over 100 miles) was uneventful so I thought I had solved he problem but yesterday, I went for another run and one way, things were fine but on the way home (this time about 23 miles each way), I saw the temperature spike and the engine boiled again. (remember there is...

                    How much is it worth? Original 1928 Tudor
                    by Jordan
                    I have considered getting another Model A to tinker with for a little while now- but a school teacher I can only afford so much. I have ALWAYS wanted an "original" car to make into a "grapes of wrath" type vehicle to just have fun with. I almost got one last year- but someone else got to it literally 30 seconds before I did.

                    I found this 28 Tudor and the owner is asking...

                    Electric Fan
                    by Jordan
                    I am just curious if anyone here has ever installed an electric fan on the front of their Model A radiator. Before you scold me, I know it won't look right... but I have a reason. Here in Texas it gets extremely hot & I drive my car year round. I have an AC so when it's 108* outside, I am comfortable in the car. When it's this hot outside, my car does not overheat. Going 55 MPH down the highway...

                    Gano Filter Questions
                    by KansasRick
                    I am thinking about using a Gano filter. I had my radiator cleaned out and tested. I don't want to plug it up. I've seen them talked about on VFF Forums before. What little I know about it is it is used in the top hose. I looked at the Gano Filter web site and quickly became confused about the size of the filter, type, and does in go inside the hose or do I spice it the hose with clamps??? Can...

                    by oldcarguy61
                    So each Drive I start out with a totally clean engine bay and after about 10 to 20 miles on my short trips getting familiar with the car, I have fine coolant mist everywhere in the engine bay especially on the generator side of the motor. Fine droplets all over the firewall and even leaking droplets on the hood side louvers working their way out onto the fender. Again it seems like the heaviest...

                    I've been reading through past posts on this problem but haven't found a situation quite like mine. My car doesn't use any water (level does sit a little low, right at the tubes when cold), and temps are pretty good to my eye. The road to my house is a 1000ft climb over 4 miles, usually do it at 45mph. Temp measures 170-175 right after pulling into the driveway with a thermometer in the neck of the...

                    New Engine Stuck!
                    by Terry, NJ
                    Well I've been preoccupied with my coupe (Redwheels) and I'd better get back to work on my Town sedan. So I haven't started it in a while and I was getting anxious about that fact. I had tried a while ago and it seemed to turn over hard with a 6 V. This time I would start it with 12V. It cranked over sometimes fast and other times slow. Duly Noted! It started a few times but didn't stay running...
