    Very odd!

    Hi guys and gals,
    well the beast got hot the other day but very quickly and after shut off and pressure release it was fine and went another 8kms before doing it again...same cure but added some water after losing a bit out of the top tank.
    so I figured thermostat was screwed. Got a new one (Oem and recommended by specialist). Today I drained the system as per rave. Changed the stat (after a bit of cursing etc&#128556. Filled through top hose, filled radiator directly through top outlet, joined the two (with cleared bleed hose disconnected). Filled top tank till it was full and fired her up. Let it idle for 15mins and added more coolant till full and she was up to temp. Felt the new stat and bottom was still cool as was bottom hose...top of stat was hot. Took old stat inside and tested in boiling water and it opened fine...weird. So I thought 'bad new stat' and proceeded to redo the whole process with the old stat back in. Same problem at idle so took her for a half hour drive, up big hills, low revs cruise sections and a bit of mash the pedal for a while. Temp gauge reads 12 o’clock with tiny movements up occasionally but no overheating. Pulled up, no bubbling and didn’t feel overly hot but still the bottom of the stat is only just warm and obviously closed. Yet I know this stat works fine! so...I’m almost ready to throw in the towel with the old girl. Any help please?
    oh and one more thing...it’s idling strange and chugging black smoke like it’s on choke with occasional lifts in rpm to 1500.
    HEELLPP! It’s driving me nuts...I just want to drive the old girl for a while 😁
    cheers in advance

    Have you pulled the spark plugs to see if any have been steam cleaned?

    Not yet but why would that cause the weird stat not opening problem? Plug change tomorrow anyway.

    Stat would be opening, the cold side is the return from the radiator and of course only a small amount of cold coolant is needed to keep the engine temp in check at idle.

    After the drive there was still a big temp difference between the plastic above and below the stat inside. I figured it was still closed.

    Is it possible you’ve got the two small hoses on the wrong outlets on the thermostat?

    As for the chugging and smoke, I’d suggest cleaning the MAF, it’s possible it’s reading the wrong intake temp and over-fueling the motor, and also bleeding the cooling system as per RAVE. Never before have I filled the radiator prior to bleeding, have topped up the reservoir as it dropped once the thermostat opened. You need to fluctuate the revs around 2000rpm to properly remove air pockets while bleeding these things.

    Cheers

    I’ll check the hoses just in case but they went on as they came off...could’ve been wrong before I started. Will make sure as per rave. Thanks.
    so cleaning the maf....does it have to be a big tin of maf cleaner. For a one off job lol or will something else work?
    cheers

    Of course there is a difference, the bottom inlet water has been through the radiator and lost much of it's heat. What's the air temperature like in your location? Cold air = cold water.

    Quick update.
    plugs changed today and all were nicely blackened. No sign of steam cleaning 😀
    cleaned the maf sensor with isopropyl alcohol till I get some proper stuff. Took her for a good drive and temp sitting mostly at 12 o’clock with occasional very slight rise. Top hose is fine and not pressurised. Bottom of stat still luke warm while top is hot .
    still think she’s rich but will do proper maf clean asap and see what happens next.
    thanks for all the help...I’ll be back I’m sure 😁
    cheers

    ps next thing, getting cruise control working...and there are no vacuum leaks. All new hoses.
