This is in answer to the posts I Called Just plain Stupidity. Ok here is basics. 1979 242 GT B21F, manual tranny. Rebuilt head, installed, started and it went to H on temp. Did not have it pressure checked.. Tried all the suggestions you guys gave. It was not sending unit. It still could be gauge, later on that. Now the biggie. I replaced the thermostat when I rebuilt head due to not having one there from the PO. Today I took the hoses off and flushed the radiator and block. MUD water was what I call it. Anyway I have clean water. Noticed upper hose not hot near radiator and lower only hot near water pump inlet. Took out thermostat, water now flows but it is still getting a little hot. The gauge now reads between N and H. Is this normal for these engines? They do not have a comp board. Is it possible for the waterpump to be going out, causing the restriction at the thermostat? Also the fan clutch seems a bit weak. I would like to know how to pull the speedo cluster to check voltage regulator on gauges. I have removed the steering covers, and the two screws at the bottom of the cluster assembly. I thought it just pulled out from the bottom but I can not get it to go anywhere. Now remember it is different than a leter model, it only has two screws at the bottom as far as I know. Any help will be greatly appericated..Thanks,,Max
