So I had the radiator replaced, coolant resovoir replaced, tightened all the hoses and clamps.

I am no longer leaking coolant, but I checked it on a whim this morning and my tank is almost bone dry, minus some dirty coolant which I assume is backwash from the heater core.

I havent noticed any white smoke coming from exhaust, only when its been cool outside. Nothing I thought was excessive. Never smelled coolant.

I assume its going in the engine somewhere just not sure where.

My 87 GT has 94k miles, so I would hope it wouldnt be a head gasket.

I am thinking intake gasket, but I could be wrong about that too.

Anyone else experience anything like this and what was your issue.


Thanks!

Don't let it get empty, otherwise air will be sucked into the system and you'll have more problems (assuming the cooling system was properly burped when the earlier work was done).

Fill the reservoir up to the correct level with coolant and monitor what happens over the next few driving sessions.

Only two places it can go are in the engine, or on the ground. If you have no puddles and it's leaking very slowly, it could be leaking onto some part of the frame or such, and evaporating such that you would never know if you didn't find the exact spot it was happening, as it wouldn't leave a puddle.

When did you last check the oil? If intake gasket is leaking then down the lifter valley or into the combustion chamber would be most likely places for it to be going.

Fill it up. Do you get bubbling in the overflow tank once the engine warms up? If so, most likely head gasket.

My 87 GT has only about 95K miles on it, and the head gasket went on it.

Can ALSO be being pumped "out the tailpipe" if something cracked or a gasket let go.

I have a similar issues.

Get a few pieces of cardboard and put them underneath the car. Park in the same spot and check the cardboard to see if it is wet or damp.

I will check the oil here in a bit, still at work

If you get a crack in the head where coolant gets dumped directly into the exhaust stream through the valve pocket, and doesn't make it into the combustion chamber, you are definitely going to smell coolant in the exhaust.

It could be that the system wasnt completely burped after the repairs.
Refill the overflow tank and monitor.
You may not have any problem.

I was thinking this too.
Also make sure your radiator cap is the "non vented" style.

Even If you "burp" the radiator, heater core, even stock engines, still has air until engine goes thru 1 to several heat cycles.

many methods of "burping" Fiero coolant system and most are bs.
If you fill right and all seals, clamps, etc, are good... The coolant system will get rid of the rest air by itself.
Yes, that could empty overflow tank if system has allot of air left to purge.

See my Cave, Coolant Fill
You don't need all of air out but only to make sure lower Tstant is covered so Tstant and sensors/senders read coolant temp.
