Again, this should be done when the vehicle is completely cooled down. Swapping to a 140-160-200 amp alternator makes a very noticeable difference in fan speed in some cars......... those temp switches come in a variety of temp ranges. If this were the case then your fans would never be commanded on even though their circuits were intact. PCM grounds the Dark Green wire for low speed. Has a rather marginal cooling system if your engines been modified for significantly higher hp levels, that cooling system can be significantly improved upon. Confirm continuity with the end of the dark blue wire and the socket for pin 86 for relay 2 AND relay 3. C4 corvette fuel system diagram. Most t-stats work by by having a thermo reactive wax that starts to expand at a set temperature, then over about 10F-20F it continues to expand, and allow heated coolant to flow to the radiator, thus the t-stat will remain closed until its rated temperature range is reached and it will open wider up to its fully open position over about a 2-5 minute time frame. Install upper and lower radiator hoses. Installation (Upper & Lower). An operation check of the thermostat can be made by hanging the thermostat on a hook in a 33% glycol solution 22 degrees (Fahrenheit) above the temperature stamped on the thermostat valve.
You'll need a multimeter than can measure DC voltage and continuity: Remove all three relays so you're only dealing with the sockets. CAUTION: The radiator cap should be removed from a cool engine only. ECT above 113°C (235°F). Be sure to keep coolant in the filling funnel. C4 corvette cooling system diagram 2 0.

When high fans are commanded they are wired in parallel. The car looks like its 95% complete but I am not confident in the routing of the coolant hoses and have no idea how to route the vacuum lines. Cold spots in the radiator indicate clogged sections.
Open the air bleeder screws located at the water pump and throttle body long enough to bleed any air out of the system. Fluidyne High Performance DB30901 - Fluidyne Oil Cooler with Fan Kits. Add ethylene glycol base coolant when coolant additions are required because of coolant loss or to provide additional protection against freezing at temperatures lower than -37 degrees Celsius (-34 degrees Fahrenheit).
