Holden VT 3.8 V6 has an overheating issue..

[@thewholls7176]

Bloody good job that..!!!! I Remember being young bloke at school and our motor mechanics teacher said if you are driving a car boys and the temperature gauge assuming you’ve got one happens to go into the red pullover leave it idling to keep the coolant circulating and sort it out on the side of the road ASAP if you keep driving and the gauge starts to drop back out of the red all that means is you’ve ignored it and most likely you’ve now chucked all the coolant out of the system which lowers the temperature at the probe and you’re now about to seize the motor…….. Don’t know if it’s true my Holden HQ had a red “TEMP” light no temperature gauge but when she started getting hot the red light used to come on very dimly before it went full bright red……. What a flashback:…!!!!!

[@ziggassedup]

Yeah fluid temp gauges weren't meant to read steam...Cheers mate.

The legend knows how to diagnose anything. These were a good car , brother did over 500,000 in his before he sold it and bought a Ve omega he only had for 3months because he hated the Alloytec slug.

[@ziggassedup]

Cheers Pete..Great old engines are the V6 Mang...Yep even tho the Alloyturd were rated with more HP the 3.8 went heaps better...Cheers mate.

[@petergoodwin2465]

@@holdenvtseries2274 spot on mate , my vz was a nightmare. I've always had old chryslers and older holdens that were great cars until I bought the Vz . That thing broke down at least every 2 weeks and horrible to work on. Best thing I've ever done is trade it for vy ss Ute. Didn't expect it to be so bad, Holden always has built a good car especially the old Holden V8. I can't stand the sight of an Alloytec now. Happy New year mate.

Nice job Zig sorting out all those issues to get the customer back on the road. Cheers mate

[@ziggassedup]

Thanks Lloyd.👍..Cheers mate.

[@CraigAB69]

Just a tip for people be careful about running just water as it can cause damage to the Rear Main Seal Housing. The coolant starts to drip from the bell housing. As of this date Holden (or what is left of them) sell the housing kit for $250 AUD.

[@ziggassedup]

Yep.

[@speedfreak1161]

Lol Nice to watch , they have there usual things to fix but there normally cheap and easy to fix yourself and bloody reliable units when maintained 👍🇭🇲

[@ziggassedup]

Absolutely mate...Cheers.

[@Thegaragefiles]

I bought one of those radiator funnel they work great, nice fix I usually drill 1/8 hole in the thermostat for an air bleed if not already equipped

[@ziggassedup]

Drilling the thermo is touch and go Dennis 'cos if it fails the supplier will say I've tampered with it...Cheers mate.

nice tip on warped thermostat housings, no water in the trans was a bonus

Good on carby bases too mate...Yeah it never goes that way luckily because the tranny oil pressure exceeds the radiator...Cheers mate.

My 2002 model Holden VY SS Commodore boiled over today at my local Supercheap Auto store but the temperature 🌡️ gauge showed up as being normal & I had recently replaced the coolant in the radiator. One of the store people & I were thinking that there was an air pocket inside of the cooling system, despite the VY V8 Commodores having a header tank on them it still managed to overheat,the radiator is 4 years old and I have never had that sort of trouble with it before,I topped it up with water at SCA today & it hasn't overheated when idling it at home so that we air pocket is a mystery. I sanded the gasket surface flat in the thermostat cover of my dads 2000 model Holden VX V6 Commodore to rectify a coolant leak which was coming from the thermostat cover gasket. I believe his has a clockspring issue as well because the airbag turns on & it stays on now,he had it cleared by a mechanic & Holden but it has come back this year with the airbag light issue !

[@ziggassedup]

Looks like you've got some projects there Russell...Cheers mate.

[@HoldenStraya]

Just need to bash the dash, Gauges sometimes fault like that. But if that doesn't work. Just bash around with parts.

[@jbproductions4884]

Awesome video very informative, I just want to ask how to fix the the clock spin because my airbag sign lights up as well

[@ziggassedup]

I'm sure there is a video somewhere...BTW it's a Clock spring...

[@davidskinner6765]

Nice one👍👍 I love my old vx

[@ziggassedup]

A great series...Cheers Dave.

[@wickedxe]

Probably needs inlet gaskets, I like the aluminium gaskets from Mace engineering

[@ziggassedup]

Not this time mate...Cheers.

[@closertothetruth9209]

are they aluminium only or do they have some kind of sealant on them too, never knew they existed

[@braidyclarke7597]

Wish I knew Mace did them I just replaced mine

[@mpfour4203]

The original Holden intake gaskets normally fail, oil mixes in the coolant. In the USA, they use the ac delco aluminium ones. Just like the mace ones. Most people never completely drain the coolant, to do that. You need to remove the knock sensor’s.

[@scotthoward4836]

Hi Zig i have a vy ecotec and it overheated yesterday due to a split bottom hose. I noticed both fans were operating at that point even before overheating. My question is, when does the smaller fan drivers side operate only one fan works now the big one passenger side but the small one drivers side doesnt even with the a/c on... or does that one only only operate under extreme engine heating hence they both worked when it got really hot

[@ziggassedup]

Sorry mare I'm not exactly sure...I do know they are 2 stage and both come on with the A/C and trigger at 104 Cels...It's known for the fan assemblies to fail....Cheers Scott.

Are Radiators easy to put in as I need a new one but I'm stuck on the farm...hope it's here nxt week.thnx

[@ziggassedup]

Yes they are.

[@darcyw8995]

From your experience zig, what would cause a stalling issue in one of these other then a Crank sensor, my VT likes to stall out every now and then.

[@ziggassedup]

When was the last time you cleaned the throttle body.?...Chances are it's a tad filthy if not the idle motor could use a clean...Cheers mate.

[@darcyw8995]

@@ziggassedup I can hear the idle motor open right up when it's stalling so I thought it wasn't, it's odd as it only has 93k kms but I'll have a look. Cheers

[@ziggassedup]

@@darcyw8995 Check the throttle body and the hose that goes under it to the switch at the back of the head...Those hoses come off sometimes and check the PCV hose while you're there...It'd the bigger hose that goes to to the manifold adjacent to the TB...

Mine does the same thing , and surges like a bitch when sitting at about 80km. It kicks back aggressively sometimes. Have no idea why 🤷

[@shanehill9831]

Can a faulty thermostat cause the radiator tank to blow from pressure ? My motor overheated and my radiator tank popped and steam going everywhere and can hear bubbling/boiling. I dont know what jas caused this

[@ziggassedup]

A bad thermostat,/water pump/,blocked radiator,/faulty fans or an air lock can all lead to that Shane..

[@shanehill9831]

@@ziggassedup it was the radiator outlet tank that blew..stupid plastic :( cant be the water pump, i recently replaced it brand new :) when i release the thermostat no coolant spurts out My radiator is only 3 yeats old also.

[@SuperLachlan1]

how you bleed these ecotec engines. Every time i try to bleed them i get a big air lock in the cooling system

[@ziggassedup]

Best way is with a spill-free fill kit.

[@dragan3290]

I have a 2002 vx and I have a ton of chemiweld or burson silver seal constantly going into the radiator. No air bubbles or or overheating issues. I have flushed the whole system with my air compressor water gun for radiator flushing and coolant system flushing. I have flushed about 4 times over time! Clean for a while and the brown emulsion starts to appear on the radiator cap? I literally get it spotless! And over time some brown shit comes out again. Lol. I don't want to do head gaskets as it's got so many gremlins but if I have to? Maybe some performance mods? Any reply appreciated cheers!🙂👍👍👍

[@ziggassedup]

Brown muck appearing in the radiator is going to be an inlet manifold gasket failure...Red muck appearing in the radiator is usually a radiator fault in the oil cooler...Hope that helps.

[@dragan3290]

@@ziggassedup the brown muck is what I'm getting. I have taken the intake manifold off ( only plenum) but not lower runners? So the issue is there? Thanks heaps for the quick reply! Top job mate.🙂👍👍👍.

The thermostat is a valve...If it doesn't open then there is no circulation.

Hey mate quick question on the same car. I've recently picked up a 3.8 vx 02 which is well due for a service, some fuckhead decided to torque the sump bung up waaaay to tight, we've done everything possible to get the bastard out but rooted the head of the bung in the process. Got any ideas aside from swapping the sump out or drill n tap a new bung hole? Got to love non-car people working on cars 🤦‍♂️ any idea would be appreciated cheers

[@ziggassedup]

Seen that many times mate...Some people should not be let loose to a tool box...I have some special sockets that will remove a bolt with a rounded head but in the past I've used a chisel to start it moving or a center punch...Cheers mate and good luck..
