TXV Bulb Styles

Postby 69-er » Wed Sep 05, 2018 7:37 pm

I'm looking at possibly changing the TXV in my 1966 Chevy truck.

The first pic is supposed to be for my application. Note the coiled bulb.

The one in the second pic has the same flat style bulb as my original. I am concerned that the coiled bulb wouldn't transfer as efficiently as the flat one. My original flat one is clamped to a flat/square section of a tube on the evaporator.

Both include 1966 in the model year range but I'm not sure if they're maybe calibrated differently.

My original TXV bulb wasn't sealed with tar tape. Maybe tape would help if I wind up getting the coiled bulb?
