Thermo Switch Location -- 88 5KSQ

[John Cody Forbes]

Yeah you are right, I saw 5kSQ and my brain added a C in there, sorry. The NA 5k's just might work the same way, I'm just not familiar enough to say.

The cold start valve is not being energized., I'm uncertain of the location of the thermo-switch that controls operation of the cold start valve on the NF engine as the diagrams in Bentley don't match my vehicle. I have a small manifold on the side of the head with a two wire sensor coming out of the top and the multifunction temp sensor in the bottom. I'm sure that the cold start valve is controlled by one of these sensors but am not sure which one. Any clarification will be appreciated. Also if anyone has thoughts of other causes for this problem please let me know.
