Hey guys,
A few of you would have read my posts over the months about my car overheating and me no knowing the cause of it, well im at the point of seriosly wanting to set the bloody thing on fire!!!LOL!
Over the past 12 months or so I have
Replaced the Thermostat completly
Had the Radiator blasted out under pressure
Replaced the water pump
Checked for blown head gaskets
Had a cooling specialist look at it
Had the thermo fan bypassed so its always on
And fully flushed the whole system
My car is STILL over heating, well almost anyway it nomally sits on 2 or 3 bars up from cold but now the norm seems to be just over half way (highway driving) and im not game enough to drive it in town cos thats when the fun begins with the gauge climbing to nearly the top. Even when i drive the car only a few blocks you can smell it running hot regardless to what the gauge says.
Any suggestions as to what the hell could be going on would be fantastic, its a series 2 auto V6.
YOU GUYS ARE MY LAST RESORT LOL!!!
Cheers!

| serverly blocked radiator maybe.the only way to really clean them out properly is pull the tanks off and clean each tube with a cleaning rod and stick the tank back on.or thermostat was a dud it has happened before. |

Radiator. Some radiators are beyond the point of cleaning.
You might need to get a new one. |

| also the water jackets in the manifold cover will sludge right up, this might be a bit extreme , but I'd be taking the motor out and putting it on a engine stand and replacing all the core plugs on the block (that way you can flush the sh1t right out of the engine , also having the thermo's bypassed puts the power system under alot of load and will cause the car to over heat if its not done properly witch is done done by hooking the thermos upto a toggle switch, so you can turn them on and off ect!! also as the lads have said it also could very well be that the radiator is just plain rooted! |

if all else fails , there is a possibility that the heater core is blocked or the heater tap needs replacing. does your heater work really hot ? cheers.

| thats it your off ya P's now ( congratch ) , I never want to go without a drink for 3 years again ..lol i agree with trizo you may need an overhaul to get all the sludge and gunk out off the motor and now you have no power restrictions , there are many possibilities for a full performance rebuild... With the radiator i would replace the lot and not go for a re-core or flushout . The plastic/alloy ones fitted to newer cars are made to be throwaway , give me some brass and solder any day .... |

I think thats what I said above, take of the manifold and take out all the core plug and get all the sludge out! Being of the p's now but is always a bonus and opens new doors to the world of crazy ass car power  |

I used to repair radiators for a living and what crazybiker said is very true.
If the radiator is blocked, just flushing it out is like putting a bandaid on the problem and sometimes not even that.
A fair few used to come in that were imposable to clean out and we would just have to get them a new radiator.
and hey if it is just the radiator at least u wont hav to pull the engine out n apart. |

nah but its fairly straight forward...basicaly get all the sludge out you can and then just flush the engine out (taking the coreplugs out) enables full block flushing!! Just BE VERY CAREFUL WHEN TAKING OFF THE MANIFOLD COVER !! YOU DONT WANNA DROP CRAP INTO THE BLOCK

| Helps if you have a "chemical assistant" to get crap out of water jackets. Once you've cleaned the water jackets to the point where nothing brown and/or sludgy is coming out, get a good radiator, a new thermostat, and a decent coolant/inhibitor, and put it back together. If it still overheats after this, you're either cursed, or your gauges are telling porkies. |

Could be air in the system, a slight air leak will raise the temperature quite a bit even causing it to overheat... Has it actually overheated or is the gauge simply saying the motor is hot? Have you had the radiator replaced?? If its new dont worry about doing this but if you havent, get the top of the radiator taken off by a specialist and they will be able to see straight through it, not just the fins on the exterior... Just an idea to float in your head :)
Anyway im sure your other half has the motor out by now, but if its still in one piece get the system pressure tested by a mechanic which is normally free & will reveal any coolant leaks, thats the cheapest and easiest job to do and it will eliminate other possible problems as well. |
Cheers,
Nodg. |

| So long as he "rodded out" the cores (cleaning by pusing something through the cores and cleaning them out that way) you know for sure there's no restriction in the radiator itself. Now that the motor itself is out, have a look inside the water jackets and see how bad it is in there. Does it look like fairly clean cast iron, or does it look like the hull of the Titanic in there? |

| The heater core is only a "secondary" radiator in a colling system sense, but in any flush, the heater tap should be open, to the whole cooling system gets flushed out. Only change that one if you have to, because if a VH is any indication off how much has to be done, a VN is likely to be worse |
