Radiator to small ??? Fan does not switch off

[ACII]

Hy all,

after some testrides ...the LS1 is doing a great Job :-)

So far i got all Problems done....no more smoke out of the exhaust / no burned smell anymore / right fluid Level !!! ;-)

Finally i am just not happy with my Radiator / fan Setup.

My Setup =

I rebuild the original Radiator of the 51 pickup. The Radiator block is new (its not Aluminium).
The size of the Radiator is around 50 x 42 x 5

Also i have installed a separate steam line..as u can see on the pics

Actually a lot bigger than the original LS1 / Camaro Z28 Radiator.

One aftermarket fan (pusher) is installed infront of the Radiator.

Today i made some measurements:

The fan kicks (low Level) in at around 185 F....
At around 196 F the fan goes high Level.


I got this datas from the PCM via OBD2.

My temp gauges shows around 10 - 15 F less than the PCM.
The sensor of the gauge is installed on the passenger side head.


Driving on the Highway (normal cruising) the pcm Shows around 199 F

In the City it goes up to 205 - 210 F

According to this Temperatur the fan is always working on high Level.

What do u think ...is the Radiator to small ??


Thanks again !!!
