Hey . Took family on trip to visit in laws in Holiday FL. 12 miles from the end of our 740 mile trip turning at a red light fan comes off and jams in the radiator and we hear clink , clang and pull over in a nice parking lot. All our coolant is on the road. The fan blades are broken and the radiator has been murdered by the fan. It was brutal. Belt and tensioner system is all good it seems. (That broke on the way home from the last trip)

I think the 8MM bolt on fan worked its way out. Anyway, I need a radiator and maybe a fan. Anyone in nearby area with a radiator and a fan or know a good junkyard nearby? I'm checking Ebay and stuff. As luck would have it, i didn't pack my spare radiator or fan ;( Advance can get a radiator by tuesday for 275.00 or so.

Also, since i'm on interstate on the way home driving at night mostly and its pretty cool, will it be ok without the fan to make it home. I don't want to buy a whole new coupler and fan. Maybe i could gut the thermostat if it starts to over heat? Can you just remove the Tstat completely or how would i make it fail open? I left my failed open thermo at home to that i just replaced on my friends 300D . Note to self, that would be a handy spare part for a road trip.

Thanks for any help

Sorry to hear your troubles. I don't have a part to help but have something that may be of interest. I once was going to rig a t-stat myself on an old tractor by essentially leaving it out. I learned that actually with the thermostat in place it creates a slower flow through the radiator and gives the fluid more time to cool. Kind of makes sense after I thought about it, but at first it seemed counter intuitive. If you gut it too much, it may be worse and run hotter than leaving a normal T-stat in place would be my guess. The fluid hauls thru the radiator too fast and doesn't have time for heat exchange. That's just my free advice and it's probably worth what it cost you Good luck though, hope you find some parts.

Not sure about your engine but the 617 has a bypass thermostat. You don't want to leave it out if you want to run cool. I'm guessing you should be able to run without a fan unless you get stuck in stop and go traffic.

While waiting on parts I've been running the silver 94 E300 without a fan clutch or fan. As long as I stay out of traffic it is fine.

Thanks all. I won't worry about the fan then and give it a try. All i know is anytime a thermo is stuck open on any car i've had , its always runs cool.

Bypass thermosats behave differently than their full-flow brethren.

You could try this guy. I haven't been there in years, and, his website is down. You are about 25 miles from there if you are in Holiday. I would give them a call. Some people love him... ...some hate him. Just be on your toes. Do you have transportation?

You can hot-wire the aux fan by shorting the high pressure switch at the rec/dryer.

or

have the blower on full heat inside the car and leave the window open.

OK,
first, do you still have the 8mm bolt? I have a spare set of everything but the radiator... and I could be persuaded to pull the radiator from my spare car and ship it all to you. I may even have the upgraded plastic fan, but I'm not sure.

DO NOT DRIVE THE CAR WITHOUT A SOLID COOLING SYSTEM!!!!!
the #14 head on the car will NOT survive.

I should have everything he need though it sound like his fan clutch may not have been working.

Members helping members, this forum is great.
Good luck on the repair.

Yeah Thanks Jon. Looking forward to it . I wanted to order from fastlane but doing it this way is more fun Jon's paying it forward for next guy broke down in TN .

On the road again. The fan bolt backed out causing teh fan to fly off and impale the radiator. Jon hooked me up with radiator, fan and bolt. Amazingly, thats all thet was bad. What caused the fan bolt to back out was ether the baaring on fan busted or some piece of old serpentine belt got wrapped around and caused it to back out somehow.

Thanks Jon. Was a lot of fun hanging with you and talking shop.
