Does anyone have any part numbers for hoses on the back of the motor and the 2 radiator hoses? By what i mean part numbers from like auto or checker. I am looking to put in a sr tomorrow and need to know if i can just get the hoses by part number or i have to go match them up....

My best advise for you is to go to the store and mix and match for hoses in the back of the engine. Buy 2 hoses that are already bent and just be creative. Make sure to buy some plastic connectors for the hoses. For radiator hoses i guess infinity sr is the same? I'm not sure on that but give it a try.

If you search my threads, I posted the Gates part number from Heavy Throttle. If you read it, I highly recommend that you don't get it. It doesn't fit and the top hose leaks.

The SR fittings are 3/4". The heater core is 5/8". Your best bet is go by shape. You need a U with a slight bend and an L for one. You'll need a swivel L for the other. This one is hard to fit because it bends weirdly.

You can try Samco Superflex hoses. They bend anyway you want. I have several feet in 3/4" if you need it for cheap. PM me.

Interesting.

Can you take a picture of the Superflex hoses you have lying around?

Also, how do you get over the problem of the two different sized fittings? Do you use a reducer coupling? If so, which one?

As far as the heater hoses are concerned I use the kit that Heavy Throttle advertises on their website. However, you should be able to buy the hoses at NAPA, also, if they stock them. I have the part numbers lying around at home somewhere. I'll post them if I find them.

For the radiator hoses I use Coolflex hoses. They look nice and have a lifetime warranty. They are more expensive than your standard Samco hoses though.

The only problem I had with them was the upper hose. Because of the size of the Coolflex hose and the location between the radiator inlet and upper hose waterneck you have to bend it just right. It was a slight pain in the ass, but I eventually got it.

Also, the couplings are too big on the Coolflex, but they offer neoprene reducer coupling with their gear, so that shouldn't be a problem.

All in all I'm very satisfied with them.

They ship fast and their customer service is friendly and helpful.

Good Luck!

For anyone that is looking for heater hoses for your sr. Go to a local junk yard and grab some from the infinity sr. They're complete bent and shape ready for you to drop right into your car.

Heavy throttle lines always bolted up perfectly for me with no leakage.

If you look closely, the swivel L from Heavy Throttle is 3/4" throughout. It wil fit, but if you look closely there will be a slight leak from the heater core fitting. If you try to tighten the hose clamp too much you will rupture the plastic fittings.

It looks to me like they got lazy and didn't do enough R&D on that one hose. The other fits, but you will have to trim to length.

Go to Google and put in Samco Superflex. It will show you pictures. They're just silicone hoses with grooves cut into them so you can bend them more than regular hoses without rupturing.

HalveBlue · 11-16-2006, 11:31 AM

Let me follow up with another question.

You stated that the Samco Superflex hoses you have are 3/4". So wouldn't those leak just as much as the HT setup?
