Coolant Change / Looking for an original hose

[Keith W.]

Pulled the lower radiator hose to drain the coolant. This junk came out and a good amount of it. The hose is covered in it internally which also has a crack/slice in it. Time to get a new hose. My question is can any of the junk get in the engine and cause issues? It ran great before I pulled the hose off at around 160 degrees. Also, if anyone knows of an original hose I can get my hands on that would be great.

I would suggest doing a complete cooling system flush. A Prestone Flush-and-Fill kit is a convenient way to do this but you'll need to replace the heater hose that the kit's "T" is installed in after the flush if you wish to return to an original configuration.

Does this car have an aluminum or copper/brass radiator?

Copper & Brass it's a 9k mile 70 LT1.

Keith - BTW I see the original embossed fan belts - my car had one of the originals - power steering - I removed it and put on a set of aftermarket belts for driving the car - for shows I reinstall the original - along with the other two repro belts - I did the same with the expensive air filter elements as well.

Thanks James. How do I ensure 100% that the hoses I have are original and/or correct? I took both off and have the codes that are on the current hoses. I have been looking at sites for replacements and I can't find the upper hose with that code. My codes are
upper:

2806195 AU;
lower:

3946854JQ GM AU
