Thanks Ron for the help; I will refill Coolant and try to video where it is leaking. Meanwhile I would appreciate if you educate me on the following :

1) If the radiator is leaking, is it better to replace with a new one or repair the old one. Seems not expensive, around 100$

2) How easy is to remove and replace with a new one?. This is my spare car, so I can do it leisurely. I have trouble removing the hose clamps. When I try to replace the thermostat, I try to compress the ends with a pliers, but the clamp will not come out of the hose. Do I need a special tool to remove hose clamp?

Thanks again for your help

 

It's probably best to replace the radiator, but this decision depends on the location of the leak. Replacing the radiator is reasonably straightforward. Just muscle those clamps and hoses, and they'll come off. A special tool isn't necessary.

Sorry for the late response. Today I found where the leak is. It is in the Head. There is a long crack running along the head. Please see the two pictures and one video below. (Click on the Video to play it). Please advice if I should Replace or repair it. Thanks for your help

 

I was worried when you stated that the leak was from the head, which I thought meant the engine head (=bad). The video clearly shows a MAJOR leak from the top of the radiator. Remove leaking radiator and install a new one as shown in the diagram. You then need to refill and bleed the system:

 

Thanks Ron. Sorry I meant radiator Head. Will replace it

 

By the way, don't bother removing the drain bolt. Just drain coolant from the radiator tap. That drain bolt is nothing but trouble.

Replacing the radiator should both fix the problem and make you love your Honda again.

 

Ron:

Sorry I forgot to ask one more question: When I buy a new radiator, which one is a good buy - The OEM (Denso) costs around 220$ against the other generic brand costs 100$; Not sure of the quality difference that costs 100$ more. Appreciate your opinion.

 

I don't have the knowledge to advise you. Maybe other members can direct you. My inclination would be go OEM and shop around.

Some questions to consider for the generic radiator: Do the specs closely match those of the OEM one? What warranties are offered? Will it bolt right in without some frustrating modification?

 

How do I jump the fan with the battery?

 

Insert a short piece of wire into the disconnected 2P connector for the coolant switch on the thermostat housing.
