coolant

Hi. I have bought 12L worth of Nulon SCRLLTU-SIX Organic Coolant from Supercheap for my VY V6 Commodore. Can I use the red stuff instead of green? I have read that the green coolants further prevent corrosion in cast blocks. I am doing a complete overhaul of the cooling system. Thermostat, Water...

Hey guys, Just ”upgraded” from a Series 1 omega to a series 1 SV6 and I have a question about the operating coolant temperature. I was driving the SV6 today and I noticed the radiator fans have been coming on a bit recently. Did some investigating and the coolant was brown and sludgy, which I...

Been stumped for a little bit and want to know what people who are a bit more knowledgeable reckon. My MY11 SV6 (late 2010/early series II/LLT) got done in for a logbook service early in July (was the 170,000km service if I remember correctly, had it done at roughly 168k on the odo, car...

Hey guys I’m very un knowledgeable about cars so I’m going to do my best to type out everything that’s happened, Brought my vx 2002 commodore lumnia from a dealership that now has me blocked and refuses to see me, After 2 days I noticed brown liquid with like copper flakes under my radiator...

G'day fellow commodore owners. I had an issue with my VE 2010 V.6 Commodore sports wagon last week. Please bare in mind, I do 90% of the work on my car myself (yes I am a female lol). I had a misfire in cylinder 4, so went and replaced spark plug and ignition coil in that cylinder, car ran...

Hellooooo, I have a 2009 VE sv6 and am having coolant problems with a ticking purge valve too. I wanna fix it myself but I really need a engine layout or diagram of some sort so I can locate everything I’ll ever need! If anyone has any clue as to where I could find a diagram of the engine...

Just have a question as to what this little flap thing is on the coolant overflow bottle? Car overheated heading down the highway yesterday, never had an issue with the cooling system prior. But earlier that day I was trying to replace headlight globe, (caprice model) and reading the manual it...

After pulling the heads to inspect and replace my lifters I've managed to put a few gouges in my block when cleaning up the deck with a razor blade ready for a new head gasket. I'm hoping the viton parts of the new gasket fill the troughs and block any coolant leaks. I'm thinking I should sand...

Hey Guys, I have a vy Calais ls1 turbo. The car overheats as soon as I start to punch it for about 10 minutes, the gauge reads in the red. No matter how hot the car is the second thermo fan won’t turn on. I’ve replaced the relay and hooked it up to a battery and still won’t start. Also tried...

Hi Fellow VF Drivers i just did a 20 km round trip from my house to Woolworths and back home in 30 degree warmth with air conditioning cranking this morning. Pulled into my garage and I noticed what sounded like bubbling nose coming from around the overflow tank. Popped the bonnet, and also...

Hey everyone, Sorry for the hogging of the forum asking all these questions, I just feel like the response is so quick and everyone knows their s**t about these cars. This is gonna be one of my last as I'm getting pretty familiar with the car now. I think during COVID it's spent more time with...

Greetings Fellow VF Drivers After some guidance from the brains trust with what coolant to get, as Clarice is due for her Coolant Change. What are people's thoughts using AC Delco Dex-Cool vs Nulon or Penrite? Previous car was a FJ Cruiser and the FJCC forum people suggested avoiding Nulon...

Hey guys I have a holden commodore 92 v6 3.8 automatic unleaded wagon. I replaced the water pump, Thermostat and fan belt 2 days ago and now my coolant is leaking below the water pump but not from it. I don't know if that part is the engine or something else, here are some pictures...

G'day, I have an 04 L67 statesman. I've recently had steam and boiling coolant leaking from the left hand side of the radiator near the top hose. Temp gauge fluctuates on freeway to work and overheating happens if I make a detour between freeway and my house (to the supermarket and so on). I...

Hi all, i was just wonder how to get the knock Sensors off my car so I can completely drain my car of coolant, as I'm only getting roughly 3l each time I drain the radiator

I have a slight leak in my radiator that only leaks when it is driven, so I'm gathering it's only a pin hole in the radiator that pushes coolant out with the pressure build up. It's not a large leak, only enough for it to slightly leak on the radiator, and smell once the car is switched off, I...

I bought an 04 model VZ three days ago, yesterday morning it started to overheat, so I pulled over and made it somewhere safe to top up with water til I got home, when filling the overflow reservoir it pissed everything straight back out. I filled up the radiator, no leaks or heat issues, but...

G'day people of JustCommodores. I am thinking of purchasing a 2005 VZ Auto Executive Commodore, it is rather cheap and has some nice bodywork done to it. It is priced at $3500 (negotiable), and only has 97,000 kms. I was unable to determine the low price, and when questioned on the issues of...

My girlfriend drove my commodore to the point where the engine overheated and shut down (I should have checked the water and coolant levels). Water was leaking from the radiator and I discovered it had a hairline crack on the base. Fitted a new radiator today and as I was topping up the coolant...

Anyone know if this coolant is any good?(tectaloy XTRA cool gold green coolant concentrate 1L) Ive heard that some concentrates munchs up the radiator.

I have done a search on this but can't seem to find anything consistent on it... Basically when I check the radiator cap, the coolant is clean, red, and consistently full... But Today I was doing weekly check on fluids and other things. I checked the coolant dipstick and found it was coated in a...

Hey guys found a coolant leak just after what the part is called? Its to the left of the water pump and under the alternator with its hose connecting to the heat tap. Also would it be best to replace the part or just sealing it. Thanks heaps guys

Got a new radiator not long ago, was just having a gander at the instructions for installation and it recommends using type b coolant(anti corrosive) but everything I've seen for the car says to use antifreeze/boil, mainly nulon long life, just wondering what you folk would say is the correct...

Could anyone help me out, took my 2008 v6 ve to a mechanic shop because I have a bad idle, they looked over it and told me that my engine mounts a rooted and need replacing, while looking they reckon they also found I have a coolant leak coming from the 'filler housing' I have no idea what a...

Hey so I've noticed my 2001 vu radiator has been slightly going down after every time I've been topping it up but my resevoir has slightly more in it, I've replaced the radiator cap but it's still happening, I'm suspecting the resevoir is stealing coolant from the radiator, is this meant to be...

I have an interesting one for you guys. 2000 VT commodore, 200k on the clock, started running rough once warm. Checked under filler cap, milky oil. Head gasket was my diagnosis. Pulled off the inlet manifold and the gaskets there were stuffed, however i already had a gasket kit and the...

Hi all, Looking to confirm - got home last night to find that the VX had a puddle of water dripping from under it. Not radiator or hoses. However, I saw that it was dripping from the front end underneath the serpentine belt off of the front end of the oil sump. Couldn't see any water...

Good day gentleman... and ladies, I bought myself a 2005 Holden VZ 3.6ltr wagon just over a year ago and ever since i've owned it, i have nothing but trouble... Please believe me, i have read over and over previous posts and whilst some have helped, none have resolved or even quiet described...

Hi everyone, I've got an 02 VY SS Sedan (GenIII LS1) that leaks a lot of coolant. I was looking over the car and found coolant leaking out the join between the flange on the drivers side headers and the exhaust/pipe to cat. The car chews through litres of coolant within weeks, but never...

My '02 Lumina has actually been a car with all the bells and whistles recently, sharing with me it's check engine warning and alarm. I took it to my Holden dealer to have this checked. They came back that the diagnostic showed up coolant temp sensor has and internal fault. They added that the...

Hey guys, I own a 2000 manual VT S-pack v6 that keeps driving me up the wall with a recent overheating issue, it has been a great car up until now. The temp gauge will get to its normal temperature and then shoot up to the max for about a minute and then go back down again. The car runs fine...

Hey Guys, As I often use this forum to get answers about my commodore, I registered today to ask you a few questions about my personal case, as it's very specific and tricky, I have a holden commodore V6 VX Executive, 2001, that I bought a few months ago around 200 000kms. I drove...
