2. Use a chemical cleaner. If flushing the heater core with water does not work, you can try using a chemical cleaner. There are several different types of chemical cleaners available, so be sure to read the instructions carefully before using one. Follow the instructions on the product label, and be sure to rinse the heater core thoroughly with water after using the cleaner.
3. Remove the heater core and clean it by hand. If the heater core is badly clogged or the chemical cleaner has not been able to remove the clog, you may need to remove the heater core from the vehicle and clean it by hand. This is a more involved process, but it is often necessary if the heater core is severely clogged.
Here are some tips for unclogging a 95 Accord LX heater core:
* Make sure that the heater core is the problem. If you are not getting any heat from your vehicle, it is possible that the problem is with the thermostat, water pump, or heater control valve.
* If the heater core is clogged, you may be able to see it through the heater core inlet or outlet. If you see any debris or build-up, this is a sign that the heater core needs to be cleaned.
* Be careful when using a chemical cleaner. Some chemical cleaners can be corrosive, so be sure to read the instructions carefully before using one.
* If you are not comfortable removing the heater core from the vehicle, you can have it done by a qualified mechanic.
