Hello All - 

 

This is my first ever post, so I hope I get it right.  I'm installing a
new water pump this weekend and I have the following questions:

 

1.      Should I flush out & replace the existing coolant? It was done
last at the shop about 2 1/2 years & 10,000 miles ago.

 

2.      What brand of coolant should I buy? All I've ever heard is low
phosphate, but I've never heard any specific brand names.

 

3.      Should I use gasket sealer on the water pump O-Ring? I saw
Permatex Ultra Copper listed.

 

4.      I'm changing several of the hoses while I'm I there, except the
long ones going to the bleeder valve. These are still original, but they
look OK. Do I need to worry about these?

 

Thank You,

Walter
