lt1 overheat problem
whenever i drive my lt1 in the city with the heater off, it overheats. But if i drive with the heater blasting the heat gauge does not go into red ( still is high in temp though)
And another weird thing is I would have to have the heater blasting towards the windshield, not towards me or to the feet.
Car does not overheat if I drive on open highway with no traffic. I already replaced the thermostat and that didnt do anything. Someone told me I may have a hole in the radiator. Did any one else have this problem here?

I had the same issue on my first 4th gen. Turned out to be a clogged radiator. Have the system flushed first, before you go throwing parts at it. It's a cheap $4 prestone kit from autozone. Set it up and flush away.
Remember to bleed the system afterwards and go from there. Hopefully that's all it is man.

Re: lt1 overheat problem
Mine did pretty much the same thing, and it turns out my fans weren't turning on at the correct temperatures, if at all. I installed a manual fan switch, and it helped a lot. I then had the PCM repogrammed by pcmforless and i haven't had to touch the swith since then. Whoever had the car before me obviously messed something up.
