Looks like a leak at the bottom of engine

It is likely the water pump is leaking and the coolant is running back under the engine. Put you finger under the bottom of the water pump near the front where the shaft comes out, if it comes back wet with coolant the pump is leaking.

The coolant keeps disappearing, we have put a new cardboard under the car for a week to check for a leak and nothing

I bet it is blowing out while under way. Get something to hook up to the overflow discharge...and see.

PRessure test the cooling system. Are you overheating? HAve you changed the thermostat, pretty inexpensive and nice to have correct, while looking for the loss of coolant...

One thing that happens like this is compression gasses entering the cooling system, and pushing coolant out. and when you get home, no real evidence.

Sounds like your water pump is leaking and your engine is overheating due to the lose of coolant.have someone top off your cooling system and pressure test it to find the leak.Which I am thinking is the bearing hole or Intake gasket corner which are both common on these vehicles.

Radio fuse keeps blowing - check tire pressure and low coolant lights come on - wipers will not go down when turned off

look for any leaks at the firewall and underneath the carpeting in your car. Mine did this a while ago and stopped when it was dry out. The check tire pressure is resettable by a little button under the right side of your dash next to - but under the instrument panel. Low coolant could be a leaking head gasket or intake manifold gasket(common), or a clogged radiator try having it flushed and look for any excessive coolant consumption or fluctuating coolant temps.

1998 Pontiac sunfire lost of coolant

you should look good around the radiator while the car is running for a while. then check the bottom of the overfill tank. If you can not find a leak ther then you can look at the hoses. dry everything up first let the car run to pressurize the radiator. I hope this helps
