A friend of my mother's who is a mechanic advised that if you change out your engine you will also need to change your radiator because the pressure in the radiator will be uncalibrated. I never heard this before. And i need a new engine, so i figured I ask around and see if anyone else has heard of needing to replace your radiator when you replace your engine.

Thanks,

 

The pressure calibration sounds like a load to me. You can replace radiators without having to worry about pressure calibration or some nonsense, so replacing the engine should be the same. I'd certainly get the radiator checked out and cleaned though.

 

that is complete bull****. they just want more money. besides, the radiator cap is what keeps it pressurized and you dont need a mechanic to change those out.

 

Ummmm what? That guy should quit his job and find an opening as a department store greeter...

 

^+1, though even that might prove to be a challenge for this fellow...

 

Maybe the Mech is thinking about old school cars when they specifically used smaller radiators, in cars that had smaller or bigger motors. ie a v6 cars radiator would be inadequate for a Big Block engine conversion. This doesn't apply to the 4.6's.

 

Sounds like somebody is trying to sell you a radiator.

 

i lol'd at this. If you go from a 4 cylinder to an 8 then it would be smart to go to a bigger radiator. No calibration is needed.

 

I hope to God your not going to let this idiot work on your car. Next he'll be trying to sell you blinker fluid.

 

You should also replace your headlight fluid every time you put new light bulbs in. Just saying.
