vy ss BF coolant leak

[ARATIC]

I think mine is seeping in the same place, but its intermitant sometimes it does and sometimes it doesnt. Wondered if its just the gasket also, but you'd be annoyed if you went to all that trouble replaced the gasket and it still leaked.

Drive belt is very easy, the tensioner is spring mounted and once the slack is loosened the belt will fall off. 2 min job.

If you buy a WP off ebay, then it wont come with the thermostat and housing. I have heard not to bother with non genuine pumps though as they never last. Geniune they are pricey though, around $500 inc thermo and housing!

Also cant this job be done without removing the radiator? There seems to be loads of space to pull the pump out

ah k same as my old falcon didnt notice a tensioner, is it a 3/8 or 1/2 drive ratchet style one(its dark and the car is covered lol)?

I agree with it would be annoying, Last time i bought a part off ebay it was ####ed and I had to do it again, might get one from repco. Will at the least have a look at the thermostat anyway.

It is odd though it literally drains the block in 5 mins from that gasket and not the weep hole...

Going to have a go on the wkend I post some pics hopefully no ranting haha.

Cheers.

The tensioner takes a 15mm ring spanner, push to the passenger side to remove the slack.

So you've already done the waterpump? If you dont want to do it again, get a genuine pump. The Repco or Bursons pumps will be (are) no better than the ebay ones.

Genuine GM pumps can be bought off ebay usa for $175 + shipping

No I was referring to my old car with the ebay comment. Where can I get a non **** one then lol

 

[ARATIC]

Holden or ebay usa. I'm trying to find out whether the pumps from ebay usa have the same part no as the genuine Holden ones sold here. I think they are as they are for a Pontiac GTO, which is just a rebadged Commodore.

Fair enough, I can't decide whether to replace the pump or not as it isn't physically leaking and more money means more to me than less money. I hate cooling systems, they plague every car I have owned.

Changing the pump today, took the old one out yesterday afternoon but ran out of day light. Will post some more pics soon. Bought the pump and **** and forgot the RTV:ranting:

Probably a good idea just to change the waterpump. Even though it looks clean and the gasket is at fault, the waterpump might have become warped where it bolts onto the block

2 Final questions: Does anyone use those radiator pellets and what are the pump to block bolts torque specifications?

Gregorys says step one 15nm and step 2 25nm....wtf does that mean is it 15 or 25?
