I have a 1997 Pontiac Firebird 3.8 V-6. My car has over 103,000 miles, and I wanted to replace the heater hoses. I can get all the hoses, and can cut off the metal crimp connectors, but do not know where to get the heater hose snap connectors (heater hoses to engine). Why GM used these I'll never know. I called my local dealer, but they said I have to buy the entire heater hose assembly, which is $161. I can get all the hoses and the heater restrictor valve (plastic fitting that connects two heater hoses together) for about $80.

Anyone know where I can buy these quick disconnects for the heater hose (to engine)? I checked AC Delco online, but only found the hoses, no snap connectors for them? Any other way I can get these hoses to mount to the engine using something else rather than these snap connectors?

THANKS in advance for all your help!
