[km5]

Hey all, iv got real rusted hose clamps on my bottom radiator hose from when i brought my vz. I felt squeezed the hose when my car was cool and it was squishy and if i remember doesnt that mean replace? the top is the same.

could someone pls help me as too how to replace hoses,coolant? i havent had any experience with these new holdens

Undo them, dump the old fluid WITH CARE, and top up with new. The GM one is as good as any. Idle the engine and top up as it warms up.
New clamps too for sure and you may as well replace the top and bottom hoses and keep the old ones in the boot "just in case".

Should also flush the whole system and refill with fresh mixture if dumping the radiator coolant.

cheers boys!

whats the go with flushing these ones, do you need to run the heater and all that?

and also what type of coolant, gossie you were saying the gm stuff which is the red coolant hay? where can i pick up a pre-mixed bottle of that from?

thanks

Pull the thermostat and flush it all out with the water hose. Have the heater turned on so that flushes as well. No need to run the engine though. You can flush it hard through one end of the hoses to make sure it's cleaning it all out.

The GM stuff was fairly clear last time I used it 3 years ago on the VY. Use whatever you prefer. I just think if the General sells it for his cars you cant go wrong.

except the thermostat is a 4 hour job just to get at on the vz. just shove a hose in the bottom radiator hose and let it flush out through the hearer tap, then flush through the heater tap hoses back out the water pump. if you squeeze the radiator hoses and they are crunchy, then theyre no good, dunno about whether theyre soft, unless theyre swollen when the car is hot

Good thinking Richard. Crazy if you don't spend the extra on new hoses though......and the rest of them too.......heater hoses.

I'm fairly particular with my Daughters car a VT, being 10 years old. Only late last year she was not all that far from home and the temp. light came up. Been well trained......she stopped and checked and found there was a pinhole in a heater hose blowing out of it. Let it cool off, got some water from a kind soul, and got to a garage and had it changed.
That was one that felt okay but was not. She could of course cooked the engine if the kept going.
