HD radiator and overflow bottles

[12000]

hello how do you connect 2 overflow bottles in a vp do you connect them in series or do you get a t peice and connect then seperately to upgrade the cooling system one holden one and the other a repco one.

do repco or holden sell proper vp holden overflow tanks im sure its just holden that sell the proper holden overflow bottles.

or do you sugest i go to holden and get a new main overflow tank and get a heavy duty vp radiator.

could you give me instructions on putting a heavy duty radiator in, looks simple but do you have to drain the coolant from the thermostat.

cheers

What's wrong with the cooling system in it? For a V6 with basic to minimal mods you shouldn't need to do all the upgrades you keep posting about (lots of threads on the same topic I see).
