Question about Holden Cars & Trucks
I am looking at a Holden Astra Sri 2004 model. During a test run, after getting up to temperature, I noticed that cooling water was returning into the header tank via the upper return tube connected into the top of the tank. Is this normal for this engine?

When the engine cools the coolant will be sucked back in. We call it an expansion tank or overflow tank..

if our engine run at 82 celcius there no reason its start boiling when you turn it off its normal for temp to raise when you turn off the engine but to start boilling thats mean our temp is higher then 84 degre check our gauge manuelly check the temp with a thermometer directly in the radiator and compare with the gauge that mean the faster you go colder its get so the radiator does its job but what weird it goes up at lower speed so not enought air goes trough the radiator are you missing a front spoiller that redirect the air to the radiator if you raise the boots you gonna have to raise the cooling capaciter of the car check it out let me no. . pierre

my husband did everything that everyone else did that had this overheating problem. It was so weird that my engine cooled at a light and heated up going down the road. I have a north star 4.6 engine and this is natorious for happening. my check engine light also came on and so I had a diagnostics done which told me my #1 injector wasn't firing , car ran like **** as well. After putting in a new water pump and plugs,ect. and realized injector was good a friend told him we could have a blown head gasket. So just to see if this was the problem I went to buy a bottle of glassbeads and the auto parts guy told us to purchase a bottle of BARS STOP LEAK BLOCK SEALER NOT RADIATOR BUT BLOCK SEALER $31.99 . He followed the directions and we waited 24 hrs. before driving it. What ever the problem was has stopped my car runs like brand new and I am loving it again. no over heating no injector problem, runs great.......I hope this helps. I know its probly a temperary fix but its a fix and now we know what the problem was. SASSY

you need to replace the heater core and pressure text the radiator cap, replace if it leaks down go to a parts store to do this also you need to replace freeze plugs if you don't they will blow and ruin the engine,a slo check that the water pump is not bad, loosen the pump belt and see if you can wiggle the water pump with fan connected, if you have any play replace the water pump. and add new anti freeze.

SOURCE: Mitsubishi L200 overheating
i have an l200 animal, i started getting the same symptoms, bubbling noises, over heating, water being discharged into the header tank, i had a good look around the engine,there was no oil in the water or water in the oil ( signs of head gasket failure) when the radiator cap was off and i revved hard nothing happened, no dip in water levels and no splashing out. i took the water pump off and the impellor had sheered off the shaft. fitted a new pump and its been fine, maybe all these cracked cylinder heads and warped heads are to do with the engine being run with the fault not being cured.

I had the same problem on my 9-5 vector 3.0 TiD with the top up coolant warning. Nearly became bankrupt trying to diagnose the problem and trips to Saab. Header tank, sensors, pressure tested etc. The Saab squaddies couldn't figure it out until it got worse. It's a head gasket failure despite passing pressure tests initially...sounds like it's still early days on yours. Had to replace the engine for near £5000.but under warranty :-) Reckon 2.5-3k at a good specialists.
