the name of the hose behind the water pump of a 1995 lincoln town-ca

Water pump bypass hose.

Basically there r a few basic names for hoses , upper rad hose , lower rad hose , water pump hose ,water pump output hose water pump hose, water pump intake hose , heater core hoses in & out.

Hope that helps & best of luck.By the way those terms l gave u arejust practical easy to understand terminologies.Best way to make sure u get the right hose is to try & figure out what parts its connected to & length thickness size etc of the hose needed & try to match it up with the different diagrams or layouts or blueprints the supplier has.
Little service note try always to replace the hose clamp & make sure u clean the two surfaces the hose contacts to too, plus be sure u check the coolant level & use a anti freeze tester to be sure the coolant is good & properly mixed, do not ever mix it more then 50/50 & try always using manufactures recommended coolant etc.
