VP V6 Overheating AGAIN!!!!!

[Cobez]

Hey guys, was driving home last night and gee what a suprise, my sh*tbox started overheating again!!

Now it has a brand new radiator, new temp sensor and it isn't losing any coolant whatsoever.......


It wouldn't drop below 3 quarters on the temp gauge, and red lined a few times. Red lined on idle and while accelerating, but didn't drop below three quarters on the gauge.

A mate seems to think there may be an airlock in the cooling system???

Is this a possibility and if so, to bleed the system is it just a matter of lossening the bleeding nipple and taking off the radiator cap and starting her up and running her on idle a few times???

[stockhorse]

When you filled the radiator the first time ,did you remove hose from thermostate housing and fill through hose until it came out thermo housing? If not you may have an airblock but if you say is not leaking coolant has level dropped?

[Cobez]

I didn't fill her up mate so i wouldn't have a clue.


No the level has not dropped at all.

check that the thermo fan works. almost cooked the engine once at a set of lights because the fuse was blown.

[Cobez]

Sweet as.....cheers mate

a fuse inside the car was responsible for my fan not turning on.
it was the same fuse as the one for the interior cooling fan.

[Cogez]

Maybe ya gauge is ****ed...simple solution is sometimes the best one :P

[Bz Kn33z]

Thermostat is prob stuffed not cooling it proper check fan fuses wireing to fan, maybe make an over-ride switch to fan so you can turn it off and on.

[aussieghostrider]

Check that the thermo fans coming on as it should do so when guage hits 1/2 way possible blown fuse as other people have mentioned, also check ya oil level.

If you dont have time to get fixed right away just leave your aircon on as this will turn your thermo fan on.

Also Maybe your waterpumps stuffed & fins arent circulating water properly..

Maybe ya gauge is ****ed...simple solution is sometimes the best one :P

Thats what I was thinking.

[Cobez]

But if the gauge was screwed, would it stay on red line?? Mine was going up and down as i accelerated etc. It would cool down a bee's dick if i didnt go above 60, but as soon as i did it would rise, and sitting at the lights it would hit redline.......

Maybe i'll chuck my old cluster in and see if it does it. Which fuse is for the fans etc under the steering wheel??


When i pulled over in the freezing cold rain, it wasn't overly warm under the bonnet at all, i had been driving for maybe about 20 minutes, just as warm as it usually is, nothing was bubbling, coolant resevoir was still full, nothing leaking from underneath......

[Cobez]

I just pulled the radiator cap off, there is NO coolant in there AT ALL (cept for maybe a few drops) and there seems to be a leak coming from somewhere in between each side of the "y" pipe on my extractors...........

Any ideas??

[Bz Kn33z]

sounds like you might have done a welsh plug. i did one under the coilpack filled it full of water and only a small hole did so much damage ended up stuffing the motor up later on down track, just see if it is, and dont drive it if it is, hope this helps

Good luck.

[Pub247]

have you checked your heater tap? If its coming out at the back of the motor i feel sorry for you. its a PIA to change welsh plugs on a motor in the car.

[Not_An_Abba_Fan]

There is a core plug on the back of the block too, it will run down the back of the engine and drip off the bell housing.

[Cobez]

That sounds exactly like what it is doing ^^^^


And yes one of my mates said it very well could be a welsh plug. That's really gay. Really really gay,

[Cobez]

Where it is parked at the moment, it LOOKS like it has dripped from the transmission cover under the car, but i can see just in front of that where it has been dripping.

Shizhouse!!!

[Not_An_Abba_Fan]

Engine out dude. Replace all the core plugs while you're at it. You may as well do the rear main seal too, that will probably leak if it isn't already.

[Pub247]

I thought it was a rebuilt motor that is in your car cobez. Someone probably can't knock a plug in straight

[savage1987]

Maybe ya gauge is ****ed...simple solution is sometimes the best one :P

lol hey Jordan, remember when we nearly fried your engine and trans by forgetting to plug the thermo fan back in?? That was one of the dumbest things we ever did.

[Cobez]

It had the rings and bearings done at about 70,000 km's ago.

[Cobez]

Might just sell the car, i'm not gonna fork out the money to have the engine taken out and out back in, not worth it for what it is.

I pretty much refuse to put anymore money into it.

Plus i'm after a new car anyway.

[Not_An_Abba_Fan]

Chuck some stop leak in it, something Chemiweld, see how it goes.

[Cobez]

But would a leaking welsh plug explain the no coolant under the radiator cap??

[Not_An_Abba_Fan]

Yes. The radiator is part of your cooling system, if a welsh plug is leaking, the coolant leaks out and the level in the radiator drops.
