Radiator Flush

[brad_m_is]

Hey
Ive got a vx supercharged calais and i just flushed out the cooling system and put new Nulon coolant in it. I was just wondering if thats ok or i need to get the coolant from holden? Also do i need to get those radiator pellets?
Thanks

It's fine as it is.. Plus, you're using a good coolant.. Coolant pellets are desirable but not neccesary..

Put em in the next time you flush.. You'll be right...

Big heads up. VT-VY with ecotec or super charged motor are funny with the coolant u use. (ur ok with the nulon) But it MUST be 50/50 with distiled water. its cos of the alloy they used in the motor. oh and the pellets thats a bit of bs holden made to sell u there brand od coolant

have i also done something bad i couldnt get the engine to flush without taking the therostat out and because its at the back of the engine on supercharged model and i would have had to remove to much stuff to get to it. so i took the top radiator hose off and ran the engine with the garden hose in the radiator until clean water started comig out the top radiator hose would this have cracked the head or done any damage to the engine?

Thanks

The pellets aren't even strictly necesary. They're made of (crushed walnuts or something) and are designed to plug up any minor holes in the system. For a well functioning cooling system, it shouldn't be needed.

Use of the pellets is like a bandaid, which only works for very small leaks. I still use them when I change my coolant, they only cost $4.95 and I change my coolant every 40,000km or 2 years, so it's not a big deal.

Some pellets are also to help lubricate newly installed water pump. Not needed if you only did a flush. If you installed a new pump then its a good idea to drop a few pellets in.
