Water temperature sensors

[Malibu46pt]

Ther appears to be 2 needed sensors for the water temp. One for the fan control and another for the water temp gage. Where are these located. On Blueprint 302 Anyone have part numbers for the sensors.

the gauge sensor has to match the gauges

Can you clarify what you mean by fan control? For non-EFI, the fan control uses a thermal switch, not a coolant temp sensor to trigger the fan relay.

Normally the temperature and oil pressure senders come with your gauge package.
Without knowing your engine set up it is hard to give you a recommendation on the fan temp switch. If you have an EFI system then you won’t need it but, you will have another temp sender for the EFI.
If running you’re running a carb then you will want the fan temp switch but what temp range you want will be determined by what temperature of thermostat is installed.
Need more information to make any useful recommendations.

A fan temp switch comes with every kit.

My 351 had the temp gauge sensor in the intake manifold just behind the t-stat. The one to run the fan was also in the intake manifold on the driver's side.
