yes, you flushed it. But did you bleed the cooling system after re-filling?

Also, did you check that the D21/Patrol thermostat freely fit? I measured a head and it seems like that thermostat will hit the back of the casting?

Hi dd

here the story

i got different thermostat now that is i think Nissan Petrol Y60 76.5 C

yes i have re flushed the cooling system too..but did not install new thermostat

at the moment i am bench testing it for few days , then install it on the week end if this doesn't work fine i will give up thermostat.


Thanks

The D21 thermostat may need to open more -- it's a lot longer.

Did you bleed the coolant system after replacing the thermostat? If not, it is likely to overheat.

Hi dd

Thanks, then that is ok i remember it is also opening around 7 to 8 mm

Hi 1200rallycar

Thanks, yes i am boiling it over a period of 4 5 days and see its response,then if i am satisfied with it i will install it to the car,because had a horrible time with previous Thermostat.



Thanks

some open at different tempratures, i think 73 degrees celcius and 78 is available usually. they should open the same amount though when open

best way to test is to put it in a mug with boiling water from the kettle and watch it open

The different models open different amounts.

The B110/B210 one opens only 8mm. See details at http://datsun1200.com/modules/mediawi ... mostat#Thermostat_Testing

Hi Guys

Has any one checked the Measurement of Thermostat opening
distance , is it differ from 82 to 76.5 C or all the thermostat open the same measurement, i felt my new thermostat opens bit lesser than earlier defective one .
