Default Heater hose routing for 94 2.2L S10/Sonoma

Does anyone have a heater hose routing diagram for a 1994 2.2L S10/GMC Sonoma?

I need to replace my heater hoses and I want to make sure that I have purchased the right hoses. The AC Delco site and other is unclear on the type and number of hoses that I need.

Thanks

You should only need 2 hoses. Last I knew, they were not interchangeable. Meaning, the S10 uses 2 different sized (diameter) hoses. They are formed specifically at the factory to fit in the tight confines of the engine bay.

Default Thank you, Mile

Thanks, Mike...I have the two "special" formed hoses and 11" of 5/8 inch straight heater hose...this is what AC Delco, NAPA and other store sites say I need.

It just seems that I am missing something...I will look at the truck closer.


Thanks again!
