Hey,

Ive recently got my grubby little mits on a RX7 oil cooler.
Its s5 type with a thermostat in it.

Now my question is does the thermostat by-pass the cooler when closed or does it act as a gate to stop the oil flow all together?

the one i had wasw a gate bud hope it helps

Howd you get around using it? did you have a pressure relief valve on the sandwich block or something?

wheres yours located gota pic ???

On my garage floor atm. but ill mount it out front when i do

My understanding is that when your oil temp is below a given spec, the oil will bypass the the cooler. Your engine will get raped if your oil is cold as fuck all the time. Outside a racetrack, you'll rarely see high oil temps anyways.

Exacatly why i wanted a thermostat on it. the thermostat is on the cooler it's self and visually looks like it just gates the oil. which means ill have to find something to releif the flow earlier on

I have an oil cooler thermostat an all it does is bypass till the temp comes up and then it closes

Worked it out

The thermostat in the cooler does not block oil flow through the cooler, Im pretty sure it acts as a pressure release valve so the cooler doesn't pop. It acts as a bypass valve also

do you know if the s4 and s6 rx7 oil coolers also have the bypass thermostat inbuilt? im sort of after one myself. how much did you pick the s5 one up for?
