Default My Honda civic is running poorly?

First off. The idle is messed up. It idles up and then it dies down and then idles up again

On top of this it overheats. I think the radiator isn't working. It overheats and then coolent sprays everywhere.

The heat no longer works either.


It's. 95 civic ex coupe

For all those things, start with the coolant. Top up the radiator if necessary, then find the coolant bleed nipple on top of either the thermostat housing or the housing where the other radiator hose connects to the engine. When the engine is cold, open the nipple (12 mm socket) half a turn and close it when a steady stream of coolant comes out. A bubble in the coolant is the most common reason for idle hunting in Hondas and low coolant is a major suspect in no heat and in overheating.

Be sure to use only Honda compatible coolant (no green stuff!) and purified water (no tap water, ever).
