Car still running hot

I have tried everything I can think of to make this car run cool.

Removed the radiator and had it dipped. the company who did this said it did not need to be rodded and i trust them.

Replace the overflow bottle with a stainless one and bought a new cap.

Flushed the under car hoses with a garden hose.

New antifreeze and water wetter.

New rubber hoses.

Wired the fan to be always on.

The thermostat does open at about 190 when driving at least at the beginning. I can watch the temperature drop from 190 when it opens.

Bled the system many times with the front end raised higher the the rear of the car. Both with the cap on and the cap off. By the way which way is right?

I now am ready to give up and remove the thermostat, but I have been told this might be bad.

Should I remove the thermostat or drill a hole in it?

Any other ideas?

Hmmm, my first thought is you have the wrong thermostat in it. Can you give us a description of the problem? Just "running hot" doesn't tell us much.

Someone stated a year or so back that the wrong cap could be an issue.

If I am idling the temperature creeps up to near 260 in about 5 minutes of idling after the car is already hot. The fan is blowing the correct direction, sucking air through the radiator.

Driving on the highway the car runs just over the 190 mark and stays between 190 and half way to 260.

Leaving the heater on and the fan blowing seems to help a little.

I have had 3 people look at the cap and tell me it is the right one. The overflow hoses does let steam out when the temperature gets over 190.

OK, that tells me its not getting adequate cooling. Again, my first thought is you have the wrong thermostat.

You can't just stick any old 190 degree thermostat in it and have the system work as its supposed to.

I think Tony posted a part number for a Stant that worked correctly. Anybody have that P/N?

If, we do the Natoli mod, which is installing the flush tee into the heater line that goes into the head, can we bleed air there, instead of the radiator?

Thanks,

Ed
