I think that my 88 na is going to bit the dust. when i got my car a year ago it had water in the rad it would leak a bit of water but not much just a week ago i draned the water and put coolant prestone extended life now almost every three days i have to put half a thing of coolant in it. so is a seal going or is it leaking

 

Check for leaks... (of course)

If there are no visible leaks there might be a problem. Feel around the carpet-area of the internal foot-wells for signs of a heater-core leak.

Do you have trouble during hot/cold starts? Blow white smoke when it finally starts?

 

it starts hard in hot and cold and smokes for a min till warm

 

If the smoke smells sweet and its a whole lot of smoke, sounds like a coolant seal failure.

 

no not a lot of smoke and does not smell sweet is there a problem with leaks on this cars

 

the factory radiator leaks at the top alot ive noticed, check for rust on the radiator which would indicate a slow leak nothing you would notice on the floor but enough to need coolant. check to see if the rad hoses are pressurized or not if theres no pressure check for leaks in hoses around the thermo housing etc. eliminate everything before you assume its a coolant seal =D

 

thanks for the help
