94A Water Pump Replacement

[landisr]

Hello again. I will be replacing it soon. Unfortunately, I can't find any DIY's on the job. But I do have a manual and the job looks fairly straightforward. However, I am a little concerned about "disturbing" the lower radiator hose. I'm wondering how brittle it might be after 22 years and 180,000 miles. And, if it needs to be replaced, how much faith can I have with a NOS piece, when it has been sitting on a shelf for at least 10-15 years? Has anyone had any success making one from parts from NAPA or ?? If so, any guidance with part #'s?

Thanks for listening.

That lower hose is a very odd shape - and it is a "T", with the outlet at the bottom for the water pump. I quite doubt you'll find anything like it in the aftermarket. It would pretty tough to reconstruct it from other hoses as well - at the least, you'd need a T fitting - and hope that it would not restrict coolant flow too much.

Hi, WA. Yes, I noted the shape. I was just thinking that there are probably hoses, a T, etc of an appropriate size, but hadn't considered potential restriction issues. Perhaps one of our "mechanic" guru's can discuss that here.. ??

In the meantime, I also noticed that list price for an NOS (aged) hose is almost $50.00.. Ouch!!

PS. I also understand that fabricating something with a T would introduce 3 new junctions ie potential leak points...

If I were in your shoes, I would buy a new hose and install it while you were working on it. Cheap insurance. Without coolant flowing through your engine, it is a multi thousand dollar paperweight that you have to push, pull or trailer to your next destination. Replace the hose.
The hose is part number 19502-MN5-000 and it is $45.24 from Partzilla. That is about the price of an oil change.
