Hello
You should check the hot/cold water valve first. I have seen the lever for the shaft on the valve break free. This causes the heat to be on all of the time. How did you determine it needs refrigerant?
hope this helps you.

2001 Honda Civic P1298, ELD Fault
This 2001 Honda Civic came in with a multitude of problems one of which was a code P1298 stored for an ELD fault (electric load detector circuit input high). The ELD sends a signal to the engine control computer so that the computer can adjust the alternator output in relation to power consumption. The ELD is located in the underhood fuse box.

Need more information - what is the specific fault code? You want to be sure of the specific code and all of the possible reasons for the fault code to be stored. You don't need...'it could be' in order to correctly diagnose and repair the problem. Please post a reply with the specific fault code for further assistance.

do you know what is the fault code?

This vehicle is still under the 3 years or 36,000 miles warranty bumper to bumper. Call Honda Dealer for a warranty repair.

Have the evaporator cleaned also flush all aircon lines.

It depends on what your car has, those are the typical parts.
Spark plugs
plug wires
cap
rotor
spark plug gapper
PCV valve and fuel filter optional
also look at air filter.

You have to check to see if the headlight connector is getting battery voltage and ground with a 12 volt testlight.

Replace the Ignition Distributor Assembly. Try to get a new unit instead of a remanufactured because the reman units have a high defect rate. Probability of this solving your issue is greater than 90%.

Yes there is, not even close. There was no 3.0 liter engine available in '08. Only a 3.5 V6 which is entirely different and shares nothing.

That is a conman problem with many air bag equipped vehicles. When you change the battery or have a voltage drop, the air bag lights will trip. You just need to have the code cleared.

Purchase a computerized handheld tool that can help you reset the light while right at home. this can be found in most auto retailer shops. Driving with the light on can cause the airbag to deploy accidentally.

I misunderstood your question, my mistake. Your belt should be replaced at your earliest convenience, but 100K is ok to wait for.

It's not the battery that is the cause. Please detail further. If there is a story please tell it.
