Hello everyone
I have a 94 integra Rs automatic DOHC Not vtec,
the radiator is filled to the top, and i sometimes drive with the
radiator cap lightly loose to get rid of air pressure, and the car
still overheats, any suggestions on wat could be the problem.
There is no leak, and i just bought the radiator off of a 2000 integra.
the hoses get filled wit air or coolant im not sure and look like they
are about to pop, thats when the car overheats.

This is maybe something obvious, but let's get it out of they way
anyway: how about the thermostat?
Btw, I wouldn't drive the car if it is overheating - you will do
damage.

Is your new thermostat OEM or aftermarket? Make sure it is OEM.

Does the manual for the car actually recommend this method
of air purging?
That's not what Honda manuals for that year say to do to
purge the system of air.

Are these radiators dead-on compatible?

-----------------------------------
If you leave the cap loose, the system won't work. Water will boil if
it's not kept under pressure (that's why you need a rad cap) Fill the
rad to the top, tighten the cap. Fill the reservoir to MAX. Turn heater
ot max heat. After you drive a while check the reservoir and top up to
MAX. After engine is cold, top up the reservoir to max again (engine
sips coolant while it cools off) and check the rad and top up if
necessary.
Use Honda premix. DON'T PUT TAP WATER IN YOUR HONDA.

The rad cap is supposed to allow a bit of air vent into the reservoir.
Keeping the reservoir full will guarantee that the engine can top itself
up when the engine cools down. A bad rad cap will not allow the system
to build pressure and the coolant will boil. Cap has to work correctly.

The cap can only raise the boiling point, not lower it. If it's boiling
with the cap on, it's boiling even faster with it off, assuming your
cap is good. If not, a new cap may stop the boiling. Worth a try, as
they're cheap.
The addition of antifreeze raises the boiling point too, so be sure you
have a 50/50 mix.
You may not need the cap tight--my BMW has been running with a loose
cap for a long time, as a workaround for a leak, OTOH my Renault could
not be run this way--but you max cooling capacity will be less.
Important when towing that trailer up a mountain in the desert heat.

if what curly says doesn't fix it, get a pressure test - suspected head
gasket failure.

yea i think it is the head gasket too i was gonna fix that soon,
