the very early ones, maybe 75-76?, were mounted above the headlight pointing rearward, kinda an open fan, maybe only cali models? saw a pic on here awhile ago.I don't know when they started installing the fan. Mine is a 78 also. The fan is mounted over the louver on the driver side right under the brake master. There are some pictures on other threads in mud. Maybe someone will chime in with the answer to your question.
Ive been trying to get my cooling fan to work for too long! I'm jealous, I have only had it work once and was thrilled to hear the humm. Now I am stuck propping the hood when it gets hot after long drives. Good for youand now that I arrived at my parents there is a fan that is still running that blows on the brake MC. Is this normal?
