Which one is which? 90 vdp
I have the old fittings, I'm trying to upgrade to R 134a. Haynes and the R134a both advise heavily not to try and put it in the low side. In the Haynes it says the retro kit will only fit on the high side. Ahhhh, how can that be? Both fittings on my engine are the same, the one by the firewall and the one by the radiator. The adapter on the retro kit will fit either.
Which is the high, which is the low? I'm guessing the one fitting by the firewall is the high? Anyone know? If I guess right, I'm playing Belmont tomorrow.

On my '91 the low side is at the firewall and the high at the radiator, my caps are still intact indicating high and low sides. Don't know if 90 to 91 are different but that's how mine is. Hope this helps.
