Do you have to pull the engine fix a fan rattle?

TMI Products

figured since it was the hottest weekend of the year, no better time to see if the repairs made a difference . I put the fresh air bellows the correct way made 1/4" carb spacers and put new carb linkage. after a drive yesterday and a drive tonight in 100* heat, the carbs stopped the dripping after I shut it off and it ran great. The knock I thought I had sounds more like the fan,marbles as people say sorta in rhythm. I have another fan that came with the car that might be better or quieter.Can it be swapped in the car or will a noisy fan cause any damage if I leave it???

Sorry, you will have to get rid of the marbles before you do extra damage. I dropped a bolt on my square coming back from California (way back when) & it smoothed out the back side of the fan. I will see if I still have it & shoot a picture for ya. The noise is probably the bolt that holds the housing to the motor has come out & is now trying to get out. Motor may have to come out to replace the fan, or if you have small hands you might be able to do it.

Is it definitely the fan and not the fan pulley that's come loose? I had that and was able to sort it on the car.

im assuming its the fan as any issues that come up are new to me. I do not see any movement in in the pulley and the noise will come and go, more so when its warm.

My fan after my trip from California. I knew what was happening, but with out the proper tools & The Samba, it was a noisy drive. Funny thing it stopped, & when I looked at the motor, the bolt was hanging out the drain hole in the housing.

its not required to remove the engine. Should only take a couple of hours to re&re the fan. You'll spend more time re&re the engine over just the fan itself.

I've done it engine in. It's just the bellows the tin cover , generator and removing the rear section of the fan housing. You need to remove the cooling flap rod and spring yet you can easily get the spring back on with a hooked tool . It's more work if you have the stock exhaust , if it's a header it's not bad.

The first time I still had the stock exhaust it was so rusted to the HE's I could not save it . I had to get a Empi quiet pack then it was easy. My noise was constant and not the fan so I went further thinking maybe the can gear rivets. I removed the entire fan housing to pull the oil pump and did it in one afternoon. Never did find what the noise was it was internal in the engine even though it ran great. One day it was not there the next there it was.
