METALLIC BLOCK SEAL-16 OZ. CAN by K & W

Q: How is this one different from another orange can with the same product title, also sold at Amazon?

If you provide a link I would be happy to see if there is a difference. I do not find a single can listed with this same title. I see a 6 pack.

Q: how about if you can’t take off thermostat.. cause my truck Thermostat come with it 2005 Dodge ram 1500

I didn’t take off my thermostat. All I did was drain the existing coolant, fill it up with tap water half way then add the CRC bottle and then top off the water. Drive it around for a week or two (500 miles). Check the radiator daily before you head out and if it does down fill it up with water. After a week of driving you will notice that the water in the radiator will stop leaking (if it works). Once it stops leaking for a couple of days then you can drain it again, flush it out with water then add in your coolant again.

Q: can we pour it into the overflow reservoir?

If I remember it's a big no on that. Take off the top hose of radiator and pour it in the hose. But you want to have room for it to flow into radiator. I think it was kinda thick so mix it with hot water then add to hose. That's my two cents.

Q: will it stop water to oil leak?

I don’t think so....think of it this way, the coolant has to leak into the combustion chamber for it to work. The high heat will fuse the particle together at the crack and eventually plug up the leak. You would have to leave it in your coolant for approx 500 miles. That will give it time for this mixture to travel into your cylinder, heat up and plug up the leak. Actually for me it only took about 200 miles and I noticed the water in the radiator stopped leaking (I check it every morning before driving out).
