Trying to locate the quick connects at autozone.

Looks like Im going to have to buy longer heater hoses from water pump to heater core. the hoses are too short to reach the heater core.. I was unable to find a connector that has the white clip inside will this one here work?

I installed two of these 4 yrs ago when they were a little cheaper ($75 ea):

Hey guys are both heater core outlet tubes they same size..I notice one connector is white and the other is black..if they are different that explains why the quick connect wouldnt work on the tube on the left

They are different sizes. IIRC, is 5/8" and 3/4" or metric equivalent.

I don't think they're different sizes. The angles for the rear pipes are just different. We've seen people install them in the wrong locations (left to right) but they worked.

the dorman 800-409 says it replaces oem numbers shown below, but the silverado lines might be a different size
More Information for DORMAN 800409

15032062, 15151873, 15151875, 15792820, 15792821, 15792822, 15834772, 15834773

doesn't seem to be a lot of seperate connectors for the pickups, looks like most of them have it built on the hose already

I picked up the dorman 800-409 from Ol'reily. Tried to see if it would connect on the left tube but I couldnt get it to click but I didnt try the tube on the right side.. I looked at autozone and both the silverado and tahoe use the same heater core.. So the 800-409 should work unless it only fits one of the heater core tubes and the other uses a different size

Well I got the left hose installed without using quick connect..Will have to buy longer hose for the right tube to work?? then ill be able to know if block or freeze plug is having issues
