Over Heating Problem

[richoiftnfs]

For any1 who knows about the cooling system on a RB20det, I'm having a problem with my rb20det(r32gtst). After about 10-20 minutes of having the car going its seems like the radiator fan is working over time to keep the car cool, and yes the temperature gauge needle slowly goes up. The radiator has plenty of coolant and engine has plenty of brand new oil in it. So it has me beat, the only thing I can think of it being is the themostat not letting enough coolant through because I highly doubt the themostat has ever been changed since it came out of the factory.

Any assitance or ideas on what the problem maybe and how to fix it would be great coz I have stopped driving my car altogether for the fear of it getting to hot and cooing itself.

my r33 did the same thing last summer the rad was getting blocked had it cleaned out & put in a new thermostate and problem solved

Ditto, plus clean between the cores on the outside, alot of gunk, incects and other crap gets in between the fins and stuffs up the cooling.
