should I have the temperature gauge sender in the input manifold or cylinder head? Or does the make any kind of difference? also where must the thermostat switch for the electric fan go? ns am reasoning gauge in the intake and also fan switch sender in the head, thanks.

should I have actually the temperature gauge sender in the entry manifold or cylinder head? Or does the make any difference? likewise where should the thermostat switch because that the electric fan go? ns am reasoning gauge in the intake and fan switch sender in the head, thanks.
I personally favor it just the opposite, Gauge in the head and switch in the intake. I choose to understand what temp the head is before I carry out the intake. JMO
Normal factory controls because that a tbi Chevy.The temp sensor controls the computer system for her fi and also is situated in the input manifold. The temp sender controls the gauges in the dash and also is situated in the head.What go the directions that came v the controller speak to placed it?

FYI - stock setup is the gauge sending unit in the driver"s next head. However, if you want to download both senders in the head over there is also a tapped and also plugged hole in the passenger next head.I right now have the stock in-dash gauge v a sending unit in the driver"s side head, and a second mechanical gauge with the sending out unit in the input manifold. Ns don"t see much distinction in temperature as whole between the two gauges, but the mechanical gauge has a wider sweep that"s simpler to see.Bruce

My buddy has a 65 Rambler with a Jegs 383 stroker,and the temp sender is screwed right into the peak of the water pump.I have never watched this done before,but it seems to job-related OK.

Chevy usually measures temp just ahead of the combine exhaust valves on the drivers side. With a V-belt driven pump the rotation favors feeding more coolant to the passenger head. The combination of warm coolant coming turn off the drivers side combine exhaust on the head that has less coolant circulation was taken into consideration to provide a gauge analysis for the hottest ar within the engine. This probably makes an ext sense in the human being of design calculations 보다 has any effect top top outcomes in the real people should the engine overheat, for this reason while ns follow the GM convention, I likewise doubt the it provides enough difference whether you review temp ~ above the drivers head or native the return ~ above the manifold. Measuring in ~ the return ~ above the pump will give a false reading as this is plan to it is in the thermostat bypass return to the intake side of the pump, therefore temps below are cooler than what"s within the engine uneven the thermocouple is top top a tee fitting so that it reads the temp that bypass coolant returning to the pump. The will of the bypass is to carry out coolant circulation in ~ the pump and engine come the exemption of the radiator when the thermostat is close up door so as to speed increase the engine"s heat up process, the entire system is designed around the "leak" prevent it turn off has little to no effect on completely warmed operating temperature and has many effects top top the engine together as maintaining the inflow temp more consistant for this reason the front two cylinders see less thermal shock from excessivly cold coolant coming off the pump.Bogie
