i need some advice. i have so far replaced the radiator with a 3 row (brand new ). installed a 160 degree thermostat and flushed the engine and i still am running 220-230 with the air on. 200-220 with the air off. this is at highway speeds. in traffic running the air it really climbs to 230. running factory fan with trans coolant lines going to radiator. the trans is not stock it is built. should i get a seperate trans cooler and ditch the stock fan for electric? i am out of ideas. i know fords run hot but this seems too hot. i did check and the therostat is opening
over heating should have a tranny coller on a built trans. need a shrould, 6or7 blade fan. just out of curiosity did you do a engine swap.need a pump that turns the rite dirrection. some pumps turn clock wise and others turn counter clockwise. hope this helps. ron
Jason; I had the same problem, and all I did to fix it was to put a shroud on the car, and ditched the electric fan. I put a cooler on the trans, and now I can't get it over 180 with the air on and a 90degree day outside. You can get a shroud at a salvage yard or at AutoKrafters, although it is said theirs are of poor quality. Good luck, let us know.
i had the facrory shroud on it when it was a 2 row but it fell apart. now i am using a 1/2 shroud. still looking for a good full shroud at a good price. i have seen some on ebay but they go for 100-125. there are no salvage yards within 50 miles of here that have any mavs or comets. they are rare down here for some reason. daydreamer--- this is the original equipment on the car. no transplants mav5946--- i don't think it is a timing issue as everything else is running perfectly elliot--- no way. the trans has a custom built tourque converter with a 3000 stall speed. the trans was built to handle 450h.p. b.t.w. when the board gets up and running full again be sure to look for my pics of my 4dr i just had painted. it will give you some inspiration i hope. it took me 9 months of bodywork to get to this point. i'm going to go get a trans cooler and se what that does. if it doesn't help it can't hurt. does anyone have a shroud to sell cheap?
This may sound really wierd, until you think about it a bit... I had similar problems, and had my radiator "reamed out". Still ran hot. This is a mostly stock 302, new water pump, hoses, intake manifold,etc. All the water lines were clean and free of gunk. I took the thermostat out and ran it and it got HOTTER! Then I put in a 180' stat (after listening to Dad) and it runs right at 190 on hot days and in slow traffic. I am talking HOT in Houston TX in August. Heat Index of 110'! Dad's theory is, if the water is running through the radiator too fast, it doesn't spend enough time in contact with the metal vanes in the radiator that dissipate the heat. If you slow it down a bit, it will spend more time being able to cool down. For $4, you can try the 180' stat and see if it works. Good luck
You should always use a tranny cooler with a higher than stock stall , the more stall you have the more heat it makes . I`d love to see pics of you`r 4 door. My 4door is purdy strait but the drivers front fender has bondo in it the drivers front door is screwed up because a long time ago a guy was puting the mav on some ramps in the car port but it wasn`t lined up right so he was backing up off of them (with the drivers door open) well the door hit one of the posts it messed up the front fender and realy screwed up the door (as you can tell in the pic in my signature you can`t see how messed up it is but trust me it needs a new door) I was so p!$$ed at him from then on I have been the only person to work on the mav . There is a crease that runs from the front pass. fender all the way into the rear door so I`m not gonna get it painted untill I replace the drivers front door & fender , the pass. front door , front fender and the rear door . I might paint it with some rattle cans so it don`t look so bad though :confused: .
Its probably a combination of things that are causing you to run hot, the 3000 stall is not helping you but even with that you should be running cooler. As mentioned a 6 blade fan with clutch and fan shroud would be a good place to start, also make sure shroud covers fan blade and blade is about 1" to 2" from radiator closer is better if you don't do the 2 above things then air will pull more from sides and not thru radiator killing cooling efficiency. You can get a 6 blade clutch fan setup for a maverick from Auto zone I'm using this setup and it works great. Also I,m running 3 core radiator, 160deg thermostat ,2800 stall, weiand water pump , even on a 95deg. day water temp never goes above 175deg no matter what type of driving I'm doing.
uhhhh correct me if i am wrong... the fan and shroud don't mean anything at highway speed. you may want to make sure your coolant mixture is right.too much anti-freeze and not enough water i am told will make you run too hot. as in other past problems folks have had onthis board, i say just for fun, run the car with the radiator cap off and let it heat up. note the temp on the guage. stick a meat thermometer down in the radiator just to verify your guages' accuracy. a few have found that their guage is wrong. also, make sure your cap is in great shape. coolant under pressure has a higher boiling point. one other thing... make sure your condensor coil (that radiator looking thing in front of your radiator) has really nice fins. if they are kinda flattened in places, or the coil is full of creepin crud, it will block flow through the radiator.hose out the crud from the coil. and you can buy a "fin comb" at home depot or lowes. one last thing.. that little leather looking strip on top of the radiator support kinda seals the hood so no air can flow around and over the radiator support.forces the air through the radiator. keep us posted.
Correct at highway speeds fan has little effect on cooling in town and traffic it makes all the difference, he did mention in traffic temp went up to 230deg its highest with ac on , maybe I missunderstood what he ment by traffic! Did it run this temp before the new radiator or transmission? what rear gear ratio are you running?
by traffic i mean intown driving or congestion on the interstate. it did run this hot before the radiator swap thats why i ditched the 2 row for the 3 row. the gear ratio is stock so i think its 2:79 or 3:00. highway gears. if it helps at 70 mph i tach at 3000 rpms. before the trans build i only had idiot lights so i don't know about temps. the coolant i am using is called 40 below. it is suppposed to run 30-40 degrees cooler than antifreeze. so far it is exactly the same
Do you have a good reliable water temp gauge? Could be out of calibration. Are you loosing coolant through the over flow?
As posted above I had the exact same problem i tried everything new rad new pump new lines flushed everything twice. Mine was running in the 200-210 range all the time doesnt matter what speed but one day i thought i would take the thermostat out and it ran the same but i decided to buy a new one anyways this time i put a 180 degree thermostat in and guess what it ran at 180 or lower. i think i had a 98 degree thermostat in before.
