WHICH THERMO FAN TEMP SWITCH FOR 260Z?

[scrumpy]

I have just bought twin 10" thermo fans for my L28 powered 260Z.    I don't like the idea of a Davies Craig type stick on temp sensor on the radiator fins or the poke into the radiator probe.

 

Anyone know if there is a screw in temperature sensor to fit the radiator inlet to the cylinder head.  It may screw into the carb heating tube hole that I have blocked off.

Any ideas welcomed.

 

I see Davies Craig sell a spacer kit with sensor to fit into the radiator hose; but I am looking for a neater way using the existing water plug holes in the engine. Maybe 280ZX had thermo fans?

I sourced my temp switch from Bursons, an 82 deg which fits into an adaptor and screws into the thermostat housing.........whilst this may be on the wrong side of the thermostat ( the bottom) it seems to work well..........the fans kick in at around 90 deg (on the temp guage) and shut down at around 85

260Z I'm copying your setup.  Sent you a PM that I bought twin 10" thermo fans off Ebay.    Can you be more specific about the part number of the switch/adaptor you bought from Bursons and other parts/wiring you used to complete my installation.

I looked up a local company called TRIDON (as in hose clamps) who make thermo temperature switches for thermo fans.  They list a thermo switch ref: TFS176 with an M16x1.5 thread.  It has an ON temp 92C and an OFF temp of 82C

 

This switch is listed for L24-26-28 in Z C and K Nissans.

 

Anyone seen or used one for their thermo fans or is there a better switch available.  I also have a new triple core radiator for my triple weber L28 + 2 x 10" thermo fans.

 

By using an original type switch I don't have to invest in tacky hose probes or radiator fin probes from aftermarket guys like Davies Craig or Derale Spal etc.

 

Any Advice welcome from someone who has already done it

Where does it go? And how much is it?

I'm hoping TFS176 will screw straight into the thermostat housing.  I'm checked out a new 240 thermostat housing and see it only has two plug holes.  One appears to be 16mm for the temp guage sensor and the other is only about 10mm - So no hole for the thermo switch.

 

I also have a pollution model 260Z Thermostat housing with an extra hole in it for something. I'll have to dig it out to see the hole/thread size. 

 

I will also take a look at my US made triple core radiator to see if there are any plugs it may screw into.

 

Availability is the usual Bursons; Repco; Auto 1 etc.  Probably going to be around 60 bucks I would say.
