Hello,

This may be a stupid question.
But does the 2006 Mustangs have a separate radiator cap or is there only a coolant cap for the coolant overflow tank?
Just wondering b/c I was going to run a coolant leak test.

Thanks

 

I have 2019 Mustang GT and I have to add radiator fluid into the expansion tank. If you flush your radiator system, I know you need to burp the system to get air out.
Good Luck

 

Ok, thanks
Do you know if I should hookup a Cooling System Pressure Test Kit to the expansion tank since there is no radiator cap?

 

Coolant system pressure checks are basically the same. If you do not have a Radiator cap then YES, the pressure test cap would go on the Expansion tank. But: Always refer to the OEM Maintenance Manual to ensure it is done IAW their procedures.
Here is a You Tube Video : Good Luck

 

WOW! How did you find this!
Ive been looking for a video like this on youtube and I couldn't find one.
The guy even talks about the PSI and everything.

Thank you sooo much

 

Not a Problem.
Good Luck
