it isnt the fan...it IS the pulley because you didnt trim the hose to match the wider radiator

if you can make the hose hit the fan your car has been wrecked BAD

Scotty I normally like what you say, but my car has never been wrecked.
Although after having my stock radiator replaced with a Mishimoto, I reused the stock hose without trimming it, and it actually was getting cut on both sides, just happened that the fan made a fatal cut before the pulley could.

I'm thinking that it's possible that whatever failed on the original radiator causing you to replace it may have caused the upper hose to lose it's integerity, maybe its a little more swollen or flexible after 100k miles than it was originally.

My 9 year old hose was too big and sloppy to fit without cutting it down to fit with the new radiator. Since that was not done, it was destroyed.

Replacement hose did not require any modification to fit, although I did remove some to try and pull it farther from the fan blades. Looking back after was a waste of time, I didnt gain anything from it.

i have looked at the fans and the hose...mmmmmm....several times???....there is no way that the fan hit the hose unless somebody did something stupid...REAL stupid

or the car is wrecked and causes the fan to hit the hose

i just changed my upper and lower hoses and it would take a HUGE blunder to make the hose hit the fan

the PULLEY is RIGHT THERE

Scotty, some of the aluminum standoffs the fans mount to on the performance radiators are too long. I've seen this a few times. A simple solution is to remove the fan on that side and use a cutoff wheel to shorten the standoffs up top about a quarter inch. Only do this if there is a gap between the radiator and the front of the fan shroud. Otherwise its not gonna help anyway.

Yeah no lie thats pretty darn scary, it happened to me on my 03'. The Left fan on the radiator was chopping away at the top hose on 7' o'clock of the hose. dint even see it till i ran my hands on the sucker.
Good thing it wasnt a cracked radiator core, thats the worst...
replaced hose and filled the coolant, and it was all good to go (:

ADVICE/TIP*** my bro is a mechanic, if youre sick of the burnt coolant smell, get a small bottle sprayer with water, runn the car and lightly spray around the areas where theres alot of spilt coolant. works (:

We are not talking about the fan blades, it is the pulley that eats through the hose right?

The original hose had a doubled section there and the new ones have a mesh that is free to slide around.

Did you notice that one end is shorter than the other by a fraction and there is an arrow on the hose showing the direction of flow and you better follow that recommendation.

If the hose is old / weak it can bulge like a balloon when the coolant is hot. Doesn't explain all cases of fan blade death, but I would imagine a new OEM hose would clear up 99% of these problems. I specify OEM since autozone hoses may be the same size, but not the same thickness or rigidity.

This happened to me when I installed an aftermarket radiator as well. I just made sure I had a good amount of clearance by cutting it, as has been suggested above. I also left the mesh that was provided, over the radiator hose, and monitored it for the next couple of weeks to see if any cutting occurred.

Best of luck.

I don't understand this thread the more I read it. Do people not properly check clearances when installing aftermarket parts?

In my case, I had a shop install the new Mishimoto radiator while installing a new timing belt kit. I didn't really think to check there work, I popped the hood, saw shiny radiator, check..drove home. And the hose only survived until basically the first time that fan turned on. I would agree it was not an issue with a stock radiator. And now is not an issue with a top radiator hose in good condition. but when radiator grows, fans move, and the top hose swells...bad things can happen.

I agree here. Stock rad and stock hose should never have problems. There's so much clearance there even if your motor mounts are destroyed.

In my case my motor mounts went poo poo. My radiator hose didn't get cut until months later. I already had trimmed the rad hose to fit with the newer rad but as the mounts got worn it put the hose closer and angled it a bit which allowed it get cut.

Default Me too...

So, I guess I need to research more and look into more when I do a project. Had I only read this thread, amongst a couple others I would have been able to be proactive rather than reactive to everything.

My wife keeps asking me, "so is this another really common thing that goes wrong with your car?" and I keep telling her, yes dear...lol
