Suggest you also check the thermo switch. This turns the radiator fan on at a pre set temperature depending on what part number thermo switch you have. I would replace the current one with the lowest temp one you can find.

Thanks, i will check that out also, it seems to come on when it gets close to the third line.
I ran the car last night and today, runs at or right below the 3rd line, much better than before when it was at the bottom and above the red line. Will bleed it more and see since there was some air in it last night.

cap is fine, tested it. Today its fine, run above the 1st line slightly on the highway, gets to the 3rd line on the streets and you feel the fans come on and the temp drops. Must have been that termostat.
Only problem is the cooling system is not holding pressure. Will drop from 14lbs to 0 in about 5 minutes. Nothing is leaking on the outside (hoses, etc.), the oil looks fine, not foamy or tanish looking. Hope the head/gasket it ok, i just had it machined and new gasket. I will keep my eye on it and see []

There may be an issue with your water pump pully, check out http://www.clarks-garage.com/
There is a procedure in the garage shop manual to check this -[align=center]TS-02, Troubleshooting - Cooling System[/align][align=left]Is the lower rad hose warm now when the thermostat is open?[/align]

Hi,
It seems all is better now, i think it was the thermostat, it runs a little above the 1st line, when sitting it traffic it goes to the 3rd, fans kick on and the temp drops back down. Funny how 2 thermostats were no good, the one we put in this last time was a german one with a small bleed type hole in it, looked different than the other one too. I will check the link you gave and see what i can find out. Still a little concerned about the system not holding pressure, unless his pressure tester was not good because i let it sit for a few minutes when i got homeand checked for air and there was pressure and no air and no fluid is missing.
Thanks for your replies

the original was replaced from a shopso i dont know, the second one that i had put in was a stant 195 degree, that made it worse, the one that was put in now is 180degrees with a bleeder hole in it and its been running fine.

Thanks for the suggestion, so far so good, it must have been that thermostat, newest problem was the altinator. Changed and all good!!!!
Now i just need to figure out the oilpressure gauge and charging gauge are always pinned to the top, unless the key is off. Most likely the plug on the cluster, will take out over the weekend or something.
