I dont need appreciation. I just do this to exercise my mind,.
Now lets see what you said - you went to a shop to ask for a genuine Honda part and that shop said they will supply you a part from their warehouse catalog pricing. Chodri saab ---- you are a bit over yourself.
These shops that you visit are nothing more than "parchoon" shops - they dont care or know about the use of a part, all they know is that "maal bikta hai aur kaam chalta hai"
for them a rad cap is perfect if it looks the same.
There are two types of japanese car radiator caps, one has an inverted dome for a vacuum valve and usually this cap is a bit taller and 90% of the times it is a 0.9 bar pressure cap.
The other type - which you want is a shorter version which has a needle type vacuum valve and was installed by AHL when the car was made. It is a 1.1 bar cap and also has a plastic grab handle.
The cost of a genuine cap would be approximately Rs 1000~2000/- depending on which stock you buy.
Now stop being childish and sounding like a broken record.
If you cannot decipher help you cannot be helped. Best use the help you get - in real life I bet you will get shot down if you act like you post...
