Stupid question ?
Are the small coolant hoses coming off the coolant tank just a standard off the shelf roll ?
I gave them a quick look , they don't appear to be anything special.
Thanks ,Dave

The steam vent line and the radiator clearing line are both 5/16” ID on the engine and radiator end. The surge tank end of both lines is 1/4” ID.

Regards,

Mike
Mike, here's what I found on the hoses that I just replaced. Though both hoses look similar externally, they have formed ends and differ greatly internally.

The first photo shows the radiator hose, on the left, where it attaches to the radiator - a 3/8" bolt fits that opening nicely. The hose on the right is from the steam port on the cylinder head and a 1/4" bolt fits it nicely. The second photo shows the tank end of both hoses and a 5/16" bolt fits both nicely.

Since we're talking about steam lines, I threw in a shot of my new setup. I'm running steam relief at all four corners of the heads now.

Also, I have your new heater hoses installed and they are AMAZING - real nice work Mike!!

Does that mean they have GM part numbers, Mike?
There's definitely GM part #s for the hoses, but I don't know them as I built my own from #6 braided.

Am I correct in believing these numbers are only valid for 2005 & 2006 SSR's only ?

IDK... To me we’re talking about the straight hoses here, not the molded ones.

I know the ones Mike sells are from the firewall to just below the water pump, and one of which connects to the lower part of the surge tank. They work for all years.

Thanks, for the kind words! Here's the engine as of yesterday after the first fire-up. The second photo is a good shot of Mike's new heater hoses - they really clean up the valve cover area!

Thanks, Jersey!

I believe the correct part#s from Gates would be:

Reservoir to Cyl. Head - 28407
Reservoir to Radiator - 28409

From the description and lengths listed they seem correct to me. They, along with all the other hoses, are common to all model years. There is an exception - see post #16.

The hoses you listed are from the heater, at the firewall.

I just got to thinking that there has to be some additional plumbing on the 03/04 models, as they have coolant going to the throttle body - the 05/06 models do not. So, the hose from the reservoir to the engine may differ between the two. All other hoses should be the same.

Went back to the Gates site and entered 04 SSR and there is a different part# for the reservoir to t. body hose. It's 18623 for the 03/04. For the 05/06 it's 28407 going from the reservoir to the cylinder head. 28409 is listed for both applications going from the reservoir to the radiator

I replaced the steam hoses with off the shelf 1/4" ID hose stock from NAPA. A little bit of silicone grease and the end of a pair of needle nose pliers to expand the engine and rad ends, hose clamps, and all is good so far. I needed a bit more length to change the hose routing to the aluminum surge tank. The stock ones were 12 years old.

First photo shows Mike's new heater hoses and aluminum tanks. Nice to be able to see and detail the billet valve cover.

Second photo is before the new tanks and hoses.

Damn, that's a purty engine. Love the aftermarket coil packs. Mine are mounted on a billet bracket which in turn is mounted low on the valve covers. They are really tightly bunched, and not enough space for the MSD coils to fit.

I really like the twin snorkel air intake. I found a nice aluminum setup, but Joe convinced me I was getting cooler air to the supercharger with the stock setup with the Magnuson rear housing.

Fascinating to see how two modified engines can look so different. Looks like you're using the same Corvette throttle body.

All my modifications are external. I don't have the knowledge to start messing with the internal stuff. You and Jerry set the bar pretty high.:thumbs

Gates parts #.

Gates #28407 is standard 1/4" heater hose. You need 19 inches for an '05, more for an '04. The engine/head connection is 5/16", will be 1/16" too small at the engine connection.

Gates #28409 is standard 5/16" heater hose. Will be 1/16" to large on the reservoir end. Needed length is 26".
