what fan shroud will fit....who bought one? how much was it? i had the 170 cid.....no fan shroud....never over ehated...now i have the 302 with a universal fan shroud and on the way home it got over 210....i am tired of it.... radiator is 16 x 21.... 4 core.... autokrafters has a fan shroud for the conversion for 119.... has anyone used that shroud on the size radiator i mentioned?
I plan on fabricating my next one.(If my electric fan idea doesn't work)I bought one from JC Whit years ago, It WAS chrome, I still have it, but it doesn't quite do it for me, doesn't allow air pull through entire radiator, leaves out the corner areas. I figure I can either add on to this one or buy some sheet metal, tabs and some beer (root) and do some magic.
I have a Ford Maverick 302 Fan Shroud for $100 if you are interested ... original used ... not those crappy repop ones ..
Are you sure everything else is up to par? Radiator cap good? Upper and lower hoses good and not collapsing at driving speed? Just a few things to think about. I would think that if it gets too hot while driving down the road that it's not a shroud problem but something else going on. clint
dont know if anyone suggested but could be a "lazy" t-stat 2 ways to check pull the old one and boil in water see how close to correct temp it opens or take an old one and gut it(so it still restrics the flow) and run the car just remember if its cranky when cold it will take a little bit longer to get up to operating temp...also make sure that the fins on rad arent bent over(crushed) had afriend who "combed"(straighted out whith something that looks like a comb so the air can flow freely) his rad fins and litterally dropped approx 20-25 degrees running temp(he crushed the fins pretty good swappin the motor, putting the fan in and the tranny cooler onjust my
I don't run a fan shroud at all. I never get over 190 even in traffic. I still run the stock 2 core radiator. I have a mild cam in the car with edel intake, Holley carb, Headers, Ect. I am no expert, but have played with these cars for many years. It can't be just a shroud could it? Is the fan to far from the radiator or bad T-Stat? It seems very strange to run that hot with a four core radiator and the open front end these cars have. Just my 2 cents Mike
the radiator is new 4 core from last year.......14 inch flex fan... about 2.5 inches from radiator....rad cap is new as well....bought when i bought the radiator.....stat is 180 degree..and it opens because i see the temp drop shortly...then starts climbing... when i am driving on the freeway...it sticks to about 195....when i am in traffic...like yesterday on the way home from work...it went over 210.....i stopped at the bank for about 30-45 mins....with electric fan on....and it cooled down to 160.... when i started to drive hom...another 15 min drive....it went up to 180...stat opened.....then climbed to 195 and stayed there..... by the time i got to my driveway...it was at 200... outside temp yesterday at 3pm was 96-99 ish.... no humidity... i talked to a guy at a shop...he said that is more than likely the fact that i am bored .040 over and that i dont have a true fan shroud.... dmhines has me hooked up..i wil get the shroud from him and try it out and see .....as soon as i can get the money to him that is....lol
There's one problem, that fan is way too small. I had a teeny little flex fan like that on my old motor, could not move enough air. Without a shroud you can easily fit an 18" flex fan, that's what I'm running now. The book said it was the right one for a Maverick, but with 3 of 4 mounting tabs broken on my shroud, it was impossible to position it just right for the big fan, got 20 miles down the road and the shroud moved enough that the fan ate it for dinner. After that I used collector bolts to move the radiator as close the the fan as I could, that helped tremendously with my temperature since I was now running without a shroud (and I still am).
.....i thought about that.....the reason i went with a 14 inch fan....the upper radiator hose....16 inch would slice it up...i need a flex hose....so i went and bought the rubber universal flex hose....it was so hard to bend that it was more in the way of the fan.... quick fix...smaller fan...so now i am paying for it... i need the stainless steel flex hose..but its 70 bucks... the only prob with 18 inch fan in my car...the radiator is only 16 x 21.. so it would over hang the radiator... the 16x21 is same size as the original 6 cyl radiator..only the one i got was from a 67 mustang 302....and its a 4 row
correct me if i am wrong guys but at normal speeds, the fan and shroud mean nuthin. may want to ( entered this before) warm up the engine with the radiator cap off. once it is all warmed up, set a meat thermometer in the radiator just to verify the accuracy of your guage. it has happened more than once here that folks found that they weren't running hot at all. just an inaccurate guage! uhhhh one other thing... maybe verify that you have the correct ratio of coolant to water. best of luck!
best ratio coolant....i am running about 50/50 because it is so hot here i dont want water boiling....what is a good ratio for southern desert were temps get over 105 for 90 days straight?? guage is a mechanical gauge...but yeah....i will check into that....
That's the way I see it. That's why I mentioned the radiator hoses being in good shape. I have seen them collapse while cruising and cause overheating. clint
the car is fine at freeway speeds....idling at stop lights and stop and go traffic and it heats up pretty quick....i saw it go from 195 at the offramp to 210 in traffic in about 5 miles.....then i would get a green light and take off...it would cool down to 207 ish.....then stop lilght and it got over 210 and then green light...cool down a little ....etc.... when i shuit it down....it was about 215 or so
I just went through this entire ordeal. Read my threads from a couple weeks back. Found out that in the end, my engine was running lean. Rather than fix the problem correctly (with Edelbrock metering rods) I took out the 160 degree thermostat, drilled 6 1/8" holes, making it a "high-flo" thermo. Also, took the stock radiator out, filled it with a 50/50 solution of muriatic acid and burned out all the calcium that had built up on it over the years. Third thing I did was take the temp transfer "wire" and move it off of the intake manifold and draped it around the top of the valve covers to keep it cooler (just in case it was heating up even if the engine was not). Also, dropped the 50/50 solution of coolant, and went with closer to 20% coolant to 80% water. Well, the radiator stopped boiling over. I can now idle for 20 minutes without going over 190, and it will cool back down to 175-180 within a mile of driving. What fixed the problem...I don't know. But I think all solutions together dropped me about 30 degrees.
I must have misread the earlier threads. With the above info I'd have to say it has something to do with the fan, shroud or radiator, cap. Might try the water wetter like on the other post. clint
