Okay, so if it's probably the radiator fan bearings. It seems to have gotten worse, now it's not only noticeable during shutdown but sometimes also while running. I've been avoiding A/C use as much as possible to delay the inevitable repair. And wondering if I can delay 3-months.
Is it likely the fan will fail altogether in this period, leading to engine overheating?
I'm poor.



@jimvw57 , for years I have thought your solution was great! Not sure I'm up to the job myself though. Can you point me in the direction of an appropriate addon fan?

How much does a fan cost on ebay, assuming you'd checked?

That's why I was asking Jim to recommend one. eBay or elsewhere.
Or anyone's recommendation. But, he's already done this.

Got mine from O'Rieleys Auto Parts, but you could probably get the same unit from just about any parts store. Hayden is a common brand..

Is the 675 cfm model sufficient? I see it is nearly one-inch thinner than the 1050 cfm model. The latter isn't much more expensive, just wondering if thickness is going to be an issue in this application.

I've got a question for anyone: If it's the radiator fan which is bad, why do I only hear the noise when the A/C is on, or hear it winding down when it's just been switched off? The tempeature is in the 90's, and after driving for an hour in this hellish heat, I still only hear it in relation to the A/C. Surely, the radiator fan must be running at least part-time in these conditions, but not a peep except in relation to AC operation.

Another thing I've noticed: purely curiosity, not necessarily diagnostic. I have been driving with the AC running on a lower setting without hearing the noise, and then had it "set off" when I hit a bumpy railroad crossing, or have gone around a corner at a sporty speed.

Ok. The Harlem Edition is in the shop Radiator fan was determined to be bad. An initial quote of $5,700.00 was floated out there. I didn't blink, as that was for the full list of the things I had talked about having done including new headlights. So, I put out a heavy wish list and the Shop Manager countered with a see if your serious number. I didn't blink cause I'm not playing, he got the message and said the shop can get me where I want to be. Which is cross country to the Pacific Coast Highway. My own Parts list is 1263.44 plus 311.84 shipping so 1600.00 dollars for Radiator fan, radiator support, Radiator, Condenser, Front Bumper cover, front impact bar. and all related items. Some items may not be needed and some items may have been over looked. All my parts would have come from MBONLINEPARTS.COM. My parts list does not Include headlights which I will source myself and struts which will have to wait. I also am not including the Fluids and a/c recharge cost and of course Labor.

Big Note the item I actually must have, the radiator fan is less than 90 dollars. lol

Now I bought my smart with front end damage. Nursed it back together and drove it 20,000 miles. I am taking this opportunity to replace all that was damaged. And get rid of some of the shoe stings and wire clothes hangers holding some things in place lol.

We will just see how this plays out.

I got a 'front end repair kit' form a place in EL Cajon Ca for $800 with the whole front end from the firewall forward. It even had the master cylinder reservoir and all the bolts!
Smart Bob and twcom like this.

I like that El Cajon Ca. place a lot and have gotten a few things from there. If I was doing this job myself I surely would have went with pre-owned parts. I just didn't have the off street work situation needed to put the car down like that time and space wise. So having to use a shop... new parts, all but possibly Headlights (I want a used Brabus set) keep any failure in the shops hands with no cause attributed to the affected part being used.

So Just in prayer for great mechanical repair results, so when the crucial rear work I want this same shop to do in the fall I will have confidence in them.

And my Smart will be sailing along the Pacific Coast Highway nice and Sweet. not to mention New York to the west coast and back.

That drive will be in May 2020. Question for you is, do you run nice parts of the pacific coast highway? Also from San Diego to Seattle.... which way is the better drive from north to south or south to north? in fact I will start a thread with that very question.
