If your 2002 Honda Civic LX is not producing heat while idling, it could be due to a few reasons. One common issue is low coolant levels, which can prevent the heater core from receiving enough hot coolant to generate heat. Another possibility is a malfunctioning thermostat that is stuck open, causing the engine to run cooler than normal. Additionally, a clogged heater core or a malfunctioning blower motor could also be responsible for the lack of heat.
why does my Honda civic overheat and doesn't heat at all
My 1997 Honda Civic EX does not over heat when I come to a stop.
A thermostat
it is right hand thread.if you are trying to do a timing belt you need to heat bolt or use a 1/2 in impact gun.
You have air trapped in the cooling system that needs purged out of the system.
First check to make sure you have enough coolant in the car.
1. Check the coolant. 2. Check the fuse for the fan. 3. Check the coolant again.
Check the heat shield on the catalytic converter
Sounds like it needs a new thermostat.
Honda Heat was created in 1960.

sounds like it might be due to bad earthing. Check earth strap from battery to body to engine.
