Hi Sujit,

I have experience with these type kits and they all work basically the same=
 by pulling gases up thru testing fluid and looking for a color change. The=
 multiple test claims relate to the amount of fluid in the kit. You don't n=
eed to use much fluid for each test.

Having said this you can also look for a blown head gasket by running the c=
ar at idle with the radiator cap off until the thermostat opens. If when it=
 opens you only observe coolant flowing you're good. If coolant gets blown =
out of the radiator instead of flowing that's a good indication of a head g=
asket issue.

I personally like the kits with the tube and rubber bulb like this one

You might be able to purchase a similar kit from your local auto parts stor=

Hope this helps

I see kits on Amazon priced anywhere from 20$ up. I dont plan to test my en=
gine 50-100 times. What is a good inexpensive kit folks like to use.
