BTDC??? what does that mean?

******** UPDATE*******

I took the radiator cap off last night while it was running and you can tell there was a lot of bubbles coming
up from the radiator. I basically did that till it flowing through normal.

Drove it for about an hour and at a red light it started overheating till I would boost and you'll see the temp
drop back to normal ( What the hell lol )

what can that be? is it the head gasket?

BTDC = before top dead center = advanced. So your base timing should be 5* advanced.

Burping the system is a necessity. If you drove around moving for an hour and the car didn't overheat then it seems fine. If it overheated when you stopped then something is wrong with your cooling fans.

By when you "boosted" do you mean while still at a stop or just when you started driving again?

is it overheating on a logging system where you can read actual temp numbers? i had a bad sensor once that would show all kinds of different readings, but with some logging software i found out it was the sensor and not the motor.

if there was trapped in the system that can also cause it to read high because he air trapped will be hotter then the coolant that is flowing through. when you got to the light there still could have been air in the system and its hitting the air pocket at the sensor. id say burp and fill the system one more time.

If you don't have a 180 thermostat in their then that would cause the temps to go up like that. OR if you have a bad stat to begin with, what brand of thermostat do you have inside?

Tell them it's not a DSM. Truth. /ubbthreads/images/graemlins/wink.gif



I called them about three years ago and they had stopped working on the GVR4. They have gone higher end. No time for old cars.

+1

A cheaper one opened late on my car and warped the head. Stop driving it till you get the problem taken care of or you will likely warp the head.

good luck and if you need help just ask. its a shame, should have done the gasket when you did the waterpump. you have to take it all back apart again.
