Silicone heater hoses

So after digging around various OEM Nissan parts sites it seems that the small hoses connecting the various coolant piping on the back of the block are all discontinued. 

Doing a bit more digging I see that some retailers offer these silicone hose sets on eBay and a few other sites. I really only need about half of em as I'm going to be welding the Throttle body coolant pipes shut. 

Has anyone used these in liue of OEM hoses? I want to do them all at once as if one bursts it's an absolute nightmare to change them especially on the side of the road. These are a pretty simple part so I can't see much going wrong but i don't usually use silicone hose except for my radiator.

BUELLER? I'll probably just pull the trigger and if it's a bust it will be a learning lesson for the community

The only car I've ever had with silicone hoses was my P71, police interceptor Crown Victoria. They're part of the original special service package.

I assume that they're less likely to fail, if they're used in that application. The car was eight years old when I bought it, and when I gave it to my dad four years later, I don't think I had changed any of them.

Interesting. Haven't heard they used Silicone In the cooling system at Ford for packages

Thanks for the info

I'm increasingly unhappy with the stock style hoses for my truck.  None of them fit as well as I'd like.  I've been on the lookout for something different, whether this or a stainless setup with couplers.

We use silicone hoses in the dirt bike world pretty consistently. I've been very happy with the durability compared to rubber, and they don't swell. The only downside I have seen so far is that they don't seal nearly as well on poor surfaces, like corroded aluminum nipples. Everything has to be pretty clean and tidy.

In reply to gearheadE30 :

Yeah I used them with my Koyo and they seeped when I used the stock spring clamps. I swapped over to t bolt clamps and haven't had an issue. I'll probably grab some small t bolt clamps to use in the back as well

I installed them on my old Cougar in 2017.  Maybe 1000 miles on them.  Hope to never replace them again under my watch.

Biggest problem with silicone coolant hoses is that they're harder to keep sealed. The silicone seem to squirm out from underneath the clamps. I like to use factory spring clamps where possible.

I had an ex-Texas DPS 5.0L Mustang that came with silicone hoses as part of the police equipment. Never any problems with them.

Kit is ordered. Being at home hasn't been good for my wallet lol. Thankfully my Union was nice enough to give me a big fat vacation check right before 

Old turbo dodges have factory silicone coolant feed hoses to the turbocharger (high temp area) and they're basically all fine after 30-35 years (seriously). As long as they're made right, they're an upgrade. 

Well they showed up and I forgot to update. The hoses themselves look good and line up with the factory ones nicely. Won't know how they work for a while as the motor is out of the car now getting redone
