Hi there this is a first for me lol i have a problem with my series 1 vn commodore i was driving along a few nights back after topping up my radiator fluid and my car started to lose power and stalled this happend 2 times before i actually got home ( had to wait for the engine to cool down before driving again). i was just wondering if anyone could tell me or give me advice on what happend i have cleaned out all my hose's that lead to my engine and my radiator from the radiator water box but it still seems to overheat also i have filled my radiator water box atleast 4 times 2day and it just seems to be endless filling as far as i know there isnt any holes in the hoses and when it stalled i lifted up the bonnet and there was alot of steam from the engine any info will be much appreciated havent had this problem before could the radiator fluid affect the way it is over heating ???

| its your crank angle sensor or coil pack overheating, both small jobs but when it happens again splash water on your crank sensor and see if it cures the problem, if so it is definately the crank sensor. other wise change your coilpack with one off a s2 and see how you go |

make sure your radiator isnt stuffed, cause it'd be steam and hard to spot depending on the leak.
also, take ur car on a 10 min drive (enough to warm the car up) so the hoses expand and the coolant flows, then check for leaks. Sometimes you can't spot a leak until ur car is warm. or, call out RAC and get them to look at it lol :P

On the same note mine seems to overheat whenever i'm stopped and the thermofan engages, but to be honest I haven't been able to keep an eye on this because my temp gauge hasn't worked for a year. But yeah would this be thermofan or possibly the radiator, I was thinking it's most likely the radiator since the thermofan still works alright. I have a very rusty system so I was thinking of flushing the coolant system and maybe taking the radiator out and reverse flushing it. So in there somewhere is a question...wait no...it's here...I was just after a knowledgeable person to give their opinion on whether or not this sounds like a radiator blockage or it just being inefficient ya know? Thanks in advance ;)
Edit: On an extra note there are no leaks, and I check the engine over while it's running every now and then. But it is an old car...(mine is a series 1 too |

would using a non anti freeze anti boil coolant cause this problem i might just have to flush the radiator to get all the coolant out and the waterbox 2

| only flush it if the system is dirty, not using enough coolant will cause ups and downs in temperature. only use coolant which has glycol in it(usually costs a bit more) the ratio is 50;50 -thats 5 litres of undiluted coolant with 5 litres of water in the v6's. leave your radiator cap off and warm the car up, this will get rid of any air pockets which heat the system up drastically. if that fails, check and replace the thermostat which is located behind the throttle body and check the operation and durability of the water pump. the fins on the pump may have deteriorated. the best way to check is to leave the radiator cap off and see if the water is circulating |

ok i found the problems
#1 had a crack in my thermostat housing where the hose goes into it from the radiator. Took of the hose and it was just curoded to the max.
#2 Have a split in my thermostat hose.
#3 where the smaller hose from the radiator goes in has snapped off
**To me it sounds like the previous owner only used water as the coolant and i am thinking its tap water at its best lol. i have replace the thermostat and the radiator and i replaced all the hose's due to not knowing if they are going to be on there way out aswell and all is sweet now not a problem simple thing to fix thanks for the info guys this site rocks
Cheers thanks 2 all |

| ok in the centre of the motor is a big silver thing that ya injectors are bolted onto, remove this and in the 4 corners of the blok ( when the manifold is removed ) are these litle pockets the the water goes into, these things sludge up real easy! unblok with a screw driver ( and be very carful noyt to drop sh1t in the blok) bolt bak on and give the system a full flush ! that should do the trick! |

yeah true nod , but...... these water jackets clog up and dont allow the water to pass cleanly! hence overheating!

| water on the extractors will cause the hissing , if you still have a water leak and cant find it I'd suggest lookin at ya core plugs on the side of the blok, holden brought the vn's out with steel core plugs in sted of stainless or brass, hence they are usualy starting to corrode out after 20yrs or so! |

| whats the updatew, im guessing you got the coolant leakage sorted and now its holding and circulating coolant. is the motor running at all or did you fix that as well? |

| lol yeh @ mechanics.......also it could be the coolent temperature sensor for the ecu as i had a simalar prob when the car overheated (went to H and stayed) fan didnt kick in so i changed the sensor with one i had and now it runs smoother and better lol..and the fan kicks in alot sooner then it did |

| yeah explain overheating, on the gauge or under the hood? if its the gauge then check the earth strap under the coil because when the main earth isnt earthing properly it tends to go through the temp gauge, giving a false reading. otherwise like jas89 said, coolant temp sensor. if its actually overheating then i think the next step is to check the operation of the thermo fan and thermostat. if worst comes to worst a new radiator, the core might be coroded and collapsed. |

| coolent temp sensor is near the thermostate (at back of engin) if u have a seris one. There are 2 that look the same ones the coolent temp sensor and the other is the mat sensor.. i think the coolent one is the lower one ....not sure where abouths it is on the series 2 engines though |
