Hello all need some help here. Recently replaced a leaking radiator and did both upper and lower hoses and the thermostat at the same time just to be safe. Since then I've had issues with the lower radiator hose coming in contact with a pulley and the engine belt. I've gone through 3 hoses now that keep getting holes ripped in them from rubbing against the belts.
When I install it too there's at least a 2 or 3 finger gap between the hose and the pulley it's rubbing on.
Didn't have the issue before doing all this work. And no I'm not buying cheapest hose I could find. Denso radiator and gates hoses with a OE (stant if I remember right) thermostat .
Anyone else have this issue and if so how'd you fix it? I'm getting tired of installing a new hose every 2 weeks. Plus coolant gets flung all over the engine bay from the belt.

I never heard about this issue before. I replaced lower radiator hose not very long time ago, and I do remember that the OEM part is flexible only if you apply some physical force, meaning that it doesn’t change its shape after being installed. I think of maybe there is a slight chance you installed it vice versa? Could you please post the picture of where it touches the belt.

It appears you are not using new OEM hoses.(and clamps)
Aftermarket hoses are a real problem on LS400 and LS430. ...improperly formed, incorrect length, thinner wall thickness, improper sleeving, and less durable rubber.
The OEM hose from Toyota or Lexus is an exact perfect fit. An aftermarket hose is not perfect but they are close. You can trim the ends slightly to shorten and avoid contact with pulleys etc.
Called the dealer. Even with my wholesale discount an OE hose is still $66. No thank you, bought one from Napa for $15 and shortened both ends. No more issues with it contacting the belts. I'm all for OE, that's why I went with a Denso radiator and not a cheap AutoZone one. But $66 for a hose is crazy.
The lesson to learn here is not that OEM hose is pricey and thus irrelevant, but that any aftermarket parts, including ones provided by NAPA, do not guarantee results and in some cases that your engine won't overheat after saving couple of bucks on the quality.

OP:
"There is scarcely anything in the world that some man cannot make a little worse, and sell a little more cheaply. The person who buys on price alone is this man's lawful prey."
You guys are out of your minds its a regular hose not a high pressure hose but a rubber hose that transports coolant. The aftermarket one will work just as fine as the oem part. As with any fix its the "fixers" job to check for leaks and such normal part of fixing a car.

New gates radiator hose resulting in engine damage
A video posted by Celsior elsewhere depicting coolant loss from newly installed Gates radiator hose purchased through Rock Auto resulting in engine overheated to the extent the head gasket(s) failed.

Aside from having a thinner (weaker) sidewall, Gates' hose was not manufactured to fit correctly and rubbing on an engine pulley cut right through it.
The guy ended up having to sell his LS400.
That's an installation error, not the fault of the hose. Some aftermarket hoses require trimming for optimum fit. I've never had an issue with a Gates hose and that's what I use as replacements on all my vehicles.

Yes, but does the aftermarket supplier of Lexus radiator hoses provide instructions to shorten hose?
Any dotted lines on hose?
Replicate correctly so the user does not suffer the consequences.
The aftermarket supplier is responsible for first time fitment, not the customer...

I kinda agree with both of you.....buy a cheap part and get problems it's kinda expected, but you should still be able to make it work

Part of the reason aftermarket hoses may need trimming is they make some ends longer so the hose fits multiple applications. This keeps costs down for the manufacturer. If they put a cut line on the hose rest assured some people would cut them first and then realize they are too short upon installation.

Amazing the customer should be made to suffer the thinking.
I interviewed Consumer Safety Advocate Ralph Nader on Television and we had a pre-interview exchange about the National Safety Council.
While he applauded the NSC efforts to teach safety and provide safety training, he was somewhat dismissive of the approach because he said you cannot teach certain people common sense or cause and effect.
Anyone in supply chain for auto replacement parts has an obligation to provide a part that fits and not one that might fit.
