What hose connects to this coolant recovery tank?

Not sure what hose works for you but I have this reservoir sitting in my garage and it doesn’t fit the 2002 Lincoln Town car Cartier edition.

What warranty comes standard from Dorman or Amazon?

Dorman provides a limited lifetime warranty on these parts. A warranty exchange is the responsibility of the seller, please see link below to Amazon's policy on automotive items. https://www.amazon.com/gp/help/customer/display.html?nodeId=15015721#GUID-7AE4D2C8-CAF9-465E-A54A-2D1C166C9385__GUID-11346DD4-FD9C-4D9F-92A7-DC70907DD149

What size is the hose barb at bottom of tank?

I did not measure the 'hose barb' on the bottom of the tank. I just looked at the factory tank on my car and compared it to the one pictured in the amazon catalog. My vehicle is a 1999 Mercury Grand Marquis with the 4.6 modular V8. The coolant reservoir that I ordered from amazon fit perfectly.

Will this fit my 2003 Mercury Marquis with a 4.6 engine

Yes. This is the correct part for that vehicle assuming yours is the standard V8 4.6L engine.

Very good replacment.

My old reservoir was so dirty, I couldn't see the level, So instead of cleaning the old one, I just replaced it, and it's as solid as OEM and the cap has a good seal.
