RB25 Thermostat opening slope

[Torques]

On my R33DET the radiator starts to get warm pretty early, it'd say possibly from 40C onwards, so not long after start.

Is this normal or should the thermostat stay closed for longer (they do have an opening slope)

 

Thanks

Sounds like yours is stuck open or someone has removed it. Stock opens at 76.5 deg and even the Nismo one opens at 62 deg.

There is little or no "slope". I have tested a number and at critical temperature they open pretty quickly.

Suspend yours (if there is one) in a pot on the stove and observe.

Thank you,

I think I just get a new one then .. I didn't know they had a small opening window.

Is there a paper gasket at the housing or is it a fluid one?

liquid gasket works fine. I also use m6 studs and nuts instead of the bolts. Makes it easier to put the thermostat housing on without smearing liquid gasket everywhere.

I usually boil the jug,  pour into an old [or yr missus's favourite] coffee mug, throw thermostat in and watch it pop open in the hot water.

Got him out ... the rubber seal was damaged so it wouldn't seal 100% anymore.

It was still the OEM unit from 1997 in there ...
