D15B 3stage vtec overheating prob.

[hatch back snail]

While going up the highway on the way to maracas yesterday i noticed while i was running out the gears (2 & 3) the temp. guage was moving from 1/2 or normal position to about 3/4.
As i reached up by grand bazar while waiting on the traffic lights it went back to 1/2 or normal position.
When I reached maracas I checked the radiator level,coolant bottle and the hoses to see if there was any leaks.Everthing was ok.
Everthing else seems to be working ok,fans etc.

I thought that maybe as it was around midday this happened,but it also happened last night when i was going back down the highway.

Note: I recently (last wk) installed a new 2 core radiator,changed all water hoses (original honda hoses).Also added honda coolant.
Thermostat is still installed.

Any suggestions or checks i can make?

did u bleed out all the air

also turn on the heater let the water circulate with rad cap off

make sure all air is out

And if that does not work you might want to check your thermostart,
it may be in need of changeing

defective fan switch perhaps?

Thanks for the info. All i have to do now is change the thermostat,but everything else works ok.Strange thing is i drive the car everyday since the temp. guage went up and it never went up since.
