I picked up a 00' Civic EX recently for $1000.00 which the previous owner had a busted radiator and she let it run hot enough to stop the engine, I was going to take the easy road first and replace the radiator and see if I could get the car running again and check for damage, so I replaced the radiator and put a pressure tester on it and its loosing pressure so there are leaks somewhere ; There is no coolant in the oil or exhaust, so before I drop in a new engine I was going to try one last thing and try a block sealer type product ( example below, ) what are yall's thoughts and can anyone recommend a good product to use ;

IMHO, they are temporary band aids at best. You need to find out where the leak is. If it's not going out on the ground, it's going into the oil pan or into the cylinders; neither of which are good places for coolant....

Do some more looking before you use a block sealer.

 

^^ i agree, look around before pouring crap into your car.
