Overheating SolvedSolved

Honda Civic 2000  150000 miles
Hello, I'm having problems with my vehicle. It overheats, evaporating all of the antifreeze coming to the deposit or water recovery system, so I need to be adding water every three days. I've already changed hoses, the thermostat, suspenders, the water pump, the radiator and many radiator plugs. I've then been told that the problem was the catalytic converter and so I changed it, but nothing ever changed. Any ideas?

Your problem must be in the gasket's head. You should tell your mechanic to remove it, check it under pressure and check the block as well.

You were right Lil, the gasket's head has been changed, it has been brushed and welded. The problem is now solved, thank you so much.

Overheating

Honda Civic 1999 Hatchback 204500 miles
I changed the radiator cause it had a crack in it and was obviously overheating. I changed the hoses and thermostat as well. The fan stopped working so I changed the relay. Every three days I top off the coolant in the morning because if I don't on the third day it will start overheating but then will go back down. It fluctuates. When I put fluid in even when cold like in the morning I notice lots of pressure built up. There's no oil in the over flow fluid. It looks pretty clean.
