Thanks again, I have a few versions of those circlip removal tools, I dont suspect that I should have a problem removing it........ haha ignorance is bliss!
Thats a great idea about the coolant level under pressure. I havent had a pressure tester for diagnostics myself. I understand about the possible bubble and the coolant level. I'm going to get the "beer keg pump kit" from a friend and try the bleeding procedure. This vehicle is 1987 N/A and I suspect that it should have the high/low thermo-switch. (three contact) Is there really a ground at that switch or is it.....
line(battery positive (+)),
low load,
and high load
Your right, the schematics are hard to follow without printing and taping together, I must do that.
Now when we're talking 60 degrees for low speed fan and 83 degrees for high........ thats celcius? I was puzzled that the thermostats opened in that range and later realized that we must be talking in metrics.
Looking back at the thermo switch I can see how they could wire it so that the power goes to the fan and then to the radiator thermoswitch which will choose:
A: open contact........................no fan
B: low resistance to ground........ High fan
C: higher resistance to ground.....low fan
My friend told me once " If its an electrical problem its gotta be the battery or the wires" (just a memorable quote)
Keep Me Thinkin!
