What Cooler Is This?

[moomoolulu]

Hey,, does anyone know what cooler this is for??

I have a sedan A/T. I'm pretty sure its not a transmission cooler since it should be with the radiator?

So, would this be an Oil cooler?

In images 1/2 it shows the piping going to something that looks like an oil filter ??

thanks...

Yeah deff the trans cooler my gt-8 looks identical.

On the gt-8 it runs into the radiator and then into that oil filter thing then the air to air cooler. Thats getting pretty serious imo.

Is yours a gt-8 or the normal auto?

Its suprises me if the auto trans has the same setup. I wouldnt of thought it would need both.

You should have 2 coolers - one in the bottom of the radiator and the one pictured above.

The cooler in the radiator works to try to keep the trans oil at a constant temp, ie heats it up in the winter/when cold and cools it in the summer.

Obviously Nissan decided that the GT8 requires a second trans cooler to preserve the transmission.

If your new radiator doesn't come with one, take it to a radiator place that will put the stock "cooler" in the bottom of the new radiator.

Whilst I don't have the CVT (My Stagea has the RE5RO5A - same as 5-speed V35's - but AWD, obviously), when I replaced my radiator I found that in winter I needed the in-tank cooler (noticeable difference in shifts due to the trans ECU's oil temp settings), so had the stock one ripped out and added to my custom radiator.

You should either get the correct radiator with the oil cooler...... or upgrade your current oil cooler when you replace with that radiator your looking at and drive slowly until everythings warmed up..... probably not the best.

Replacing with the correct radiator is the best option as i have seen a chart that shows the best operating temps for the traction oil and it actually likes being reasonably warm (traction effect goes up with increase in temp within its operating range).

If you go with a bigger air to air i would use a thermostat.... assuming the black round thing is an oil filter and not a thermostat.

You need to find that graph im talking about that will let you know what temp thermostat you would need... cant remember where i found that now.

If you do pull it all apart check that black round thing is a filter as im keen to know myself?

thanks for the info...

so basically keep the stock cooler and rip out the cooler thats in my current radiator... ?? or.. get another cooler??

my radiator is leaking, thats why i'm changing it out.. called up a few wreckers around Sydney and the price for a radiator was around 400... so i felt better off just buying a new one...

austingtir: keen on that graph if you ever find it again...

Yep, keep the stock cooler and make sure that your new radiator has a transmission "cooler" in it.

If that means you need to get the original OEM one taken out of the busted radiator and put into the new one, so be it.

i already purchased my new one.. it's not for A/T.. my plans were to just buy another cooler for the transmission when i was buying it...
