This truck is a 1986.5 Nissan Hardbody. It has the Z24 engine. According to my local parts store, Two heat ranges are offered. They are 180 & 195. The OEM according to the parts store is 180. I called the local nissan dealer & the said it was 87C. Conversion is 188.6. I need to know which one is the right one for best performance. Thank you.
