Hi all, I am going to do the intake gaskets on my 2002 GP GT this weekend and need few questions answered before I start......thanks

1) Will garrage tempeture...40 degrees if I`m lucky....cause any problems ?

2) Should I use the RTV sealant that came with the gasket set ?

3) Do the coolant elbows need a sealant ?

4) What needs to be done to switch the coolant?...just flush and replace

any other words of wisdom that anyone would like to share will be appreciated........thanks again
