On my 1998 Chevy C1500 pickup with a 305 V8, I replaced the OEM factory aluminum heater hose quick connect fitting at the manifold with an improved steel quick connect fitting about 8 years ago. It had not been leaking, but I recently decided to completely eliminate this failure prone heat fitting. I'm glad I did, because touching the connector's release tabs caused them to disintegrate. br>To remove the old fitting, I used a 27mm (or 1 1/16)deep socket. I used a 7/8" deep socket to install the new AC delco heater control valve/fitting. br>I used the Gate 28479 (90 degree, 3/4") heater hose and a constant spring clamp I had on hand to attach the new AC Delco fitting (to heat core fitting at firewall). br>I decided to replace the other radiator hose (return from heat core to engine) with 3 feet of 5/8 Gates bulk heater hose I picked up from a local parts store. br>I used a Lisle no-spill funnel to top off the radiator with about 6 quarts of 50/50 Dexcool. br>Hope this helps someone finish this much-needed upgrade.
That heater hose was replaced with a rubber hose with a 90 degree molded end, and it now works perfectly! Worries about the unit falling off in the middle of a road trip are a thing of the past. To keep the hose in place, I used good ol' screw clamps, and I haven't had any problems since! It was well worth the few dollars to make this change.
The heater inlet pipe is connected to the heater bypass valve by this pipe. The original hose fitting's neck, where you tighten or loosen it (not the threads), was completely rusted through. It was pointing towards the intake manifold, and I had no idea it was the source of my problem. The coolant had gotten away from the corrosion completely. It's a good thing I replaced it because of the oxidation. All of the heater hoses, as well as the water pump, heater core, radiator, thermostat, serpentine belt, and pulley bearings, are being replaced.
Fits the thermostat housing, but the heater hose is a little too big. It will work, but it will cause the hose to bulge. I'm hoping that this doesn't lead to a hose failure down the road.
The hose from the heater core output is connected by a perfect fit 97 Blazer screwed into the top of the engine.
I needed to replace a quick connect fitting, so I used this. It comes with a built-in reducer. The reducer helps to keep the heater core from corroding.
All of my coolant hoses needed to be replaced, so I did. In a 1999 Suburban 454, I used this to replace the flimsy quick connect hose and fitting on the top of the engine. This fitting allows you to use a standard hose and clamp instead of the special quick connect hose.
