Hello again. I've made progress on the brake system at the front(for now, rear next). Anyway, engine tune-up in progress. What would be nice to find out from the forum is part numbers for the upper and lower rad hoses. Heater hoses look to be all 5/8 so no big deal. Did a search but didn't find any info. I did read a couple of things that caught my attention. One was changing the tranny fluid, that hadn't crossed my mind. Two-the dash A/C isn't working so I was going to have it looked at but read the comment about R12 vs R134 and the light bulb went off. I've changed the gaskets before on other vehicles but glad of the reminder. Thanks for any help. Road trips will be soon.

Upper is carquest 20980. Lower is 25530 or 20842. I am working on the underdash a/c on mine right now. System held a vacuum so I am going to replace the compressor clutch and the dryer. Still have some R12 from my old shop and nothing else even comes close to ice cold in these older systems.

Here are the OEM numbers:



The return heater hose to the radiator is often 3/4" hose. Good luck.

Thanks guys.

Does this hoses fit the older ones like mine? 1979 454?

Try this:



This is the oldest stuff I have.
