I gotta say no even though I haven't used it a ton. But I also wasn't getting much heat out of the original heater core. A while ago before any vintage air install, the heater never really seemed to get hot. Additionally, the thermostat I thought was old and frozen or something, but that has...
That was sort of my thought as well. I've just been putting it off and haven't done it yet even though I installed it over a year ago.
I think since I don't drive it so much and the heat hasn't been an issue to me yet so I just say I'll do it later. But I really have to get it done.
Good job. I installed the same unit, but the last (most important) part I didn't do was actually fill with the R134a stuff for the AC. I believe they suggested taking it somewhere like a shop to have them fill it.
Do you mind me asking if you did this or just bought a kit and did it yourself?
