Radiator Working Too Well?

[4core]

Hey all,

Not too sure if this is a tell tale sign of a future problem but my R32 GTS-t will cool down (the temp needle drops alot) when im driving in traffic when the out side temp is lower than 24 degrees?

I have a 32 GTR radiator in there, but i dont think that would be the cause surely.

It take FOREVER for it to warm up on idle and has never ever overheated on me. even on 40 degree days with AC on, it has never had a drama?

I have a front mount in the way also.

Anyone? or am i just being paranoid?

Cheers

well....do you run a thermostat? It should stay closed when stuff is too cool

[hojak]

Thinkin same with duncan. If you are running thermostat, could be stuffed and stuck open

I have a 50mm aluminium radiator and it takes a while to warm up but once its up to temp it doesnt change much, Might drop down to say 73-75 deg C on a cold night on the freeway. Which isnt enough to notice it on the stock temp gauge.

For anybodys who is interested 50deg C is where the temp gauge just starts to move above the cold make on the stock gauge.

Cool, i think my thermostat is bollocksed then...

Cheers guys!

Isn't that a good thing??

Why would it be a good thing? Having it open means that the engine takes longer to warm up meaning more petrol and because it's not at the operating temperature, the engine is wearing out when it's not supposed to.

its good in summer but come wenter haha ull still there a while worming ur engin up and cooling it down.. but id rather this than the heat problem i just started having with my new setup.. last night was just crousing around off boost for lets say 40 mints and my water temp went up to 92 !! so i parked the car up.

i didnt think that the new turbo will generate soo much heat but it dose even tho i have ceramic coated everything.. i might see if i can get a turbo heat bag from somewhere and ill need to make some air duct to flow some freash air into my pod filter which at the moment is getting real damn hot air into it by the looks of things even with the vented bonet up there..

nah get a new thermo in there, they are about $20 (rb30 one fits) see how that goes.

ecu runs rich when cold so you aren't helping fuel economy either

Got an a/m rad and a stock ecu?

[xr8eater]

hey duncan at what temp does the ecu start to cut back on the fuel?

also if you were having a track day would you recomend taking out the thermostat for optimum cooling+fue econemy?

[adam-__-]

I don't know much about the thermostats, but wouldn't taking it out be the same thing as leaving it in during the track day? Because once the engine's warm, the thermostat's open so the engine is already trying its best to cool the engine? Taking it out would be the same thing, no?

The way I see it is that the thermostat's only there to help the engine warm up faster.

Correct me if I'm wrong guys.

Cheers

Well if u do its because the temperature conversion/correction table in your ecu doesnt match your a/m rad
