Gregtastic Posted July 18, 2013 Report Share Posted July 18, 2013 So I was just curious for you guys who daily drive your 510s how hot does your car run? I drive my care about 15 miles to work every morning and them temp gauge stays between the M and the P ... if you could tell me how hot that is id be very thankful! thinking about getting one of the oil temp gauges from auto meter so I can let my ADD rest a little but I dunno where to screw it into the block... any help would be great!

Just Joel Posted July 18, 2013 Report Share Posted July 18, 2013 Oil temp? You want water temp gauge and the sensor mounts below the thermostat in the thermostat housing ;) Quote Link to comment

Gregtastic Posted July 18, 2013 Author Report Share Posted July 18, 2013 Oh alright cool thanks mr joel! Do you happpen to know the size fitting? Quote Link to comment
Just Joel Posted July 18, 2013 Report Share Posted July 18, 2013 Can't remember for sure but I think I ended up drilling a new hole and tapping the housing for the new sensor. That way I was able to leave the original gage functional :) Quote Link to comment

KlassicMotion Posted July 18, 2013 Report Share Posted July 18, 2013 What enigne do you have? My L20B has two coolant ports off the Thermostat housing. L16 did not. I don't remember for sure, but I think you can just put the L20B housing on the L16, if you want to go that route. I think you can still buy them new. Check with your Nissan Dealer.

DanielC Posted July 18, 2013 Report Share Posted July 18, 2013 I would suspect the Datsun engines use a BSP size fitting for the temp sender on the thermostat housing. Quote Link to comment
Carwson Posted July 18, 2013 Report Share Posted July 18, 2013 The L16 and L20B t-stat housing are interchangeable. Did it on my L20B swap in my 2 door because I had aftermarket coolant temp. gauge installed but it did not fit the sensor hole on the L20B. Quote Link to comment
Gregtastic Posted July 18, 2013 Author Report Share Posted July 18, 2013 Yea I got the L 16 Quote Link to comment
datzenmike Posted July 19, 2013 Report Share Posted July 19, 2013 The second hole on the L20B is for the thermal vacuum valve for the vacuum advance and EGR. It prevents them working until the motor is warmed up.. If you don't care about either just conect the ported vacuum directly from the carb to the vacuum advance and you can remove the TVV and use the hole for an after market temp gauge. Another option is a 280z or zx thermostat housing. Some have 4 threaded holes ... one water by pass, one temp sender and two temp switches. Quote Link to comment
KlassicMotion Posted July 19, 2013 Report Share Posted July 19, 2013 This might be a cheaper and easier option. Just make sure the sensor doesn't hit the thermostat. http://www.ebay.com/itm/70-78-DATSUN-240Z-260Z-280Z-THERMOSTAT-HOUSING-WITH-SENSOR-TAP-/321159372839?pt=Motors_Car_Truck_Parts_Accessories&hash=item4ac6972027&vxp=mtr Quote Link to comment
Gregtastic Posted July 19, 2013 Author Report Share Posted July 19, 2013 well the easyist option seems to just tap a hole into the housing which should be no problem... thanks guys i do very much appreciate all your guys wisdom Quote Link to comment
