    Has this happend to anyone my fan blade ate my radiator! Ok this is the second time I thought my motor mounts were bad (they were) I replaced them thinking this caused the notor to lurch forward into it.Been driving it for a while no problems.just finished the clutch 3 days ago only been driving it around town then crunch it ate it big time. the first time it only cracked the upper hose inlet just had to be resoddered this time it has to be recored.I was thinking of moving it forward and inch and putting a stock blade on it to solve the issue of it happing again but I want to know why I dont want to just put a band aid on it if there is sonething else wrong

    So which way is it moving,,,,,,is the engine jumping up and hitting the radiator outlet or moving forward and hitting the radiator? Do you have a flex blade on it,,,,,,,,is that the stock radiator????? How much space between the fan and radiator????? And what were you up to when all this drama happened,,,,,,

    Mine ate the rad in the 64 Chevy right after I said "check this out"... I replaced the old mtr mounts and a year later tore them in two again eating my rad. I keep my foot out of it now.

    Later,

    The first time it it hit the upper inlet with a small amount of evidence of it moving in to core a a couple of small nicks. I assume its the stock radiator, the holes to mount it all match up, it is not a stock blade, but its the one that came with it when I bought the van. I dove this from S.CA to the SF Bay aera and for months till the first it did it. It dose it when I'm changing gears I think. This time ( after I had changed the motor mounts) it didnt jump up just forward A LOT it bent one of the fan blades and I have this cool circle in my radiator.I wouldnt call the fan a flexi one the blades are real stiff and has been on the van for years. This last time I was at a stop light putting her into first making a right turn and kinda gunning it a little there was traffic I was just trying to merge I dont think I was to aggresive,and then there was this great grinding noise I thought oh *@!%$#@ what now, it cant be the clutch its not the radiator till I pulled over, lifted the coffin lid saw the stream and mist she was dead

    The transmission mount keeps the engine from moving forward, so thats the place to check,,,,,,

    Transmission mount was replaced when I did the clutch I am talking about the rubber dounut I could not find a replacement so I got one that was bigger stuck it on my drill press and shaved it down enough with a file to make it fit I had to pound it in with a mallet so there is no slop there. This van did not come wit a 9" rear but the guy I bought it from put one in would this have any affect? Also the front was in the guys words "shaven" I dont know how this done it looks like all the leafs are there.

    Can you start it up, block to wheels and set the parking brake, or tie it to a tree,,,,,,,,then give it the gas in 1st gear and work the clutch to load down the engine and see if the engine moves????

    On Chevy when the water pump bearings starts to go, the fan will starts to wobble some. Would think it get worse under load. Like taking off from light???

    Water pump. No the fan is pretty stable. The genneator went out and it was a wierd european one so I made new lower and upper brackets wich entailed taking off the fan and pully to mount the upper bracket so I am pretty sure its not that it seemed pretty solid removing and replacing.

    It looks to me to be stock its the 170 the radiator looks stock and it looks to me like everything is as it should be. This is my first van the only I have to go off of is old manuals other peoples pics of the engine and seeing them at the junk yard

    But how close is the fan to the radiator? It could be too close to it for a bunch of reasons like spacers or wrong pulley or pump,,,,,and someone here can tell you how much space they have between their fan and radiator on their van,,,,,

    One inch is really close,,,,,do you have any spacers between the fan and the pulley? And where did the fan rub the radiator,,, on the top, bottom, or the left or right side ? that whole engine could be twisting and making the blade hit one side of the radiator. Try pushing the trans with your leg near the trans mount,,,,see if the trans moves side to side,,,,

    There is no spacers between the fan and the pull but the pully has a second space for another belt. I can move the transmission a little I dont know any better but it would seem normal to me no slop just a small amount of movement

    It rubbed the radiator bad enough to bend one fan blade that made a nice circular grove into it.

    I went out again to really try and move it just in case I was being to light with her its nice and tight very little transmission movement the new bushing is doing its job I would say. the one I pulled out was not really whole when I did the clutch

    This might be a long shot, but when you dropped and replaced the drive shaft to do the clutch, was there plenty of free motion to get the caps back in the saddle on the yoke?
    I'm just wondering if the rear end isn't trying to shove the whole engine tranny unit forward on acceleration. I have had rear axles slip the center pins in the leafs on a chevy Nova before ,, makes a mess of things. I do not know how a ford is set up.

    there was plenty of free play when I removed the drive shaft to do the clutch so I dont think its forcing the engine forward there but I am far from experienced in such matters. this is the first time really working on somethingout side of changing plugs and oil.I'm kinda leaning toward the idea of the fan being to close.Its not the stock blade which has allways bugged me and it might not be the stock pully extending to far forward along with blade.

    Donvian was on to something as allways he asked if there were spacers between the pully and fan. It turns out the pully was acting like a spacer it has a place for two belts. The stock one is an inch less in depth, no second space. Didnt compare fans yet. So hopefuly thats all that is wrong, I'm still thinking of spacing the the radiator out a little just in case.

    You still need to hear from some Ford guys on how much space is there between the fan and radiator on their 6 cylinder vans. You might have some kind of a wide blade on there,,,,,and that pulley is on there so it doesnt rub the harmonic balancer. How many blades on your fan,,,,,how wide are they? You still need to brake torque that engine and see how much it moves
