MGB-GT MGB GT A/C

[budk1953]

Purchased a 70 GT in rough shape last spring (told is hadn't been started in over a year)and when I got it home I realized it A/C (dealer installed I guess). Well I cranked it over a couple of weeks ago the darn thing blew cold air! Now all I need is to find a manual since I can't read the worn knobs.

Lucky find!

Good deal! Nice to have A/C in the GT during those nice, humidity-free Maryland summers.... /ubbthreads/images/graemlins/grin.gif

Can you post a picture of it. I have 2 AC set ups and maybe 1 of them will match up.

Here's a picture. Thanks

Is that what you have rick?

 

[hottvr]

These 2 are very similar.Fan speed is on the left and temp is on the right. Turn knobs clockwise for increased fan speed and colder temp. See attachment

Yep, "frogeye's"...make sure they're also hooked to the center vents.

How does it make cold? Are there any other parts that you need for it?

 

[hottvr]

Need :compressor,evaporator, dryer, hoses,vents,switches,freon,--cold air.

 

[budk1953]

Only real concern was the old type of freon but I found a local guy who has a stockpile. Got lucky again.

~IF~ you flush it well and put the adaptors on the Schrader valves properly you can use 134a with good result. Johnson's "Freeze-12" will work in it as-is, too. And it'll be a LOT less expensive. If you do flush it, be aware it'll need to have oil replaced too.

Odds of finding that are pretty slim huh....without breaking the bank that is.
