hello,

I ll be replacing the engine in the car that I have and I want to prevent the same thing that has happened already ( by the previous owner ), .. it over heated

I ll be changing the timing belt ( along w/ changing the water pump and tensioner ), oil pan gasket, valve cover gasket, replacing the rear main seal ( pe ), radiator, hoses ( upper and lower ), w/ also changing the torque convertor seal on the transmission ( pe aka past experience ) ..

what can I get into while the engine is out ... from this happening again

 

You forgot the most important part.....Change the head gasket.

 

I take it that is the weak link I these engine(s) than ... ?

 

It's by far the most common issue.

 

In my experience with my 2004 civic with 204k miles, the reason why the car overheats is lack of maintenance to the cooling system. I would first check to see if the head gasket bad before replacing motor. If not, replace thermostat, radiator, maybe heater core for good measure, and replace coolant.
