I have a 1995 Honda Accord with the VTEC head gasket water pump and timing belt was replaced right before I bought it well it’s over heating so I changed the thermostat upper and lower radiator hoses and radiator and both fan sensors and temp gauge sensor I also did the gas check on the radiator and that came back negative I also checked heater core and I can’t find any leaks confused on why it might still be over heating also check both fans and they work anyone have any other ideas

 

Have you checked for air on the cooling system..

 

^what he says.

Make sure you removed air by using the bleeder on the backside of the thermostat housing.
Park car on level ground. Keep engine off.
Remove radiator cap, open bleeder valve.
Should have a steady stream of coolant come out of the bleed valve. Close it.
Fill radiator to top.
Fill reservoir to the max cold fill.
Turn on engine and monitor temp gauge.

 

I did that and still over heating. I did the radiator gas test again and it was clean then I tried the sizzle with the oil and it sizzled so I’m guessing it still must be something with the head gasket or head still
