Under the engine there are two hoses with coolant that connect near the oil filter housing. Approx. 5/8" ID 12" long. They seem to have a molded bend in them. Are they special hoses or just standard 5/8" water hoses?

Here are the part numbers: 1236179 and 1236178 I paid 29us with shipping from brentwood volvo in st louis. Ask for Rich and he'll get them.

They are molded hoses when you get them from the dealer and each has a unique part number.

You may be able to use standard hose but it will be a metric size. I don't remember seeing a size on them but 16 mm is close to 5/8". These need to be good hoses as they carry the coolant for the oil cooler and they always have hot coolant in them.

Do you know a source for these besides the dealer? FCP Groton does not have them.

I replaced mine recently using dealer hoses. This is one instance where the dealer parts are, IMHO, actually worth the money. If I recall correctly, I paid about $15-20 each for the hoses that go to the oil filter.
