    Angry Gwm shows overheat

    Hi,
    I am driving a 2.5 DTCI single cab 4x4 and experience some heating problems. It shows the temp rises, i losing power but when i stopped everything was normal. It shows hot but it isn't. It shows in the red but i can still put my vinger in the water and it is not burning my vinger. I then discovered that when i driving and the problem started i switch it off and after a while on again and everthing come back to normal. After a few kilos same story. Did anybody experience the same problem and how do you fixed it?

    Dit klink baie vreemd. Ek dink jou sensor is besig om te gaan. Of daar is n draad af...

    My first guess was also a faulty temp sender unit but maybe also a sticky thermostat, possibly also on its way out. Possibly the ECU also picks up that the car has overheated and goes into a limp mode hence the drop in power, but once you turn off and on again it resets the fault and the engine continues to run properly until the sender unit/thermostat plays silly buggers again

    To be safe I would replace both temp sender unit + thermostat along with fresh OEM/good quality coolant.

    Rather spend a little on these important parts than damage the motor

    The critical part here is thermostat. Replace this urgently.

    On any healthy engine, you should not be able to put your finger in the water. It sounds like your thermostat isnt opening correctly.

    PS - Faulty temp sensors wont blow the engine, but a faulty thermostat will...

    Die GWM gaan die 25ste Sept garage toe om die fout te soek.
    Ek sal terugvoering gee as dit herstel is

    Bakkie terug gekry van agente - Turbo inlaat pyp gat in, dit was blykbaar die rede hoekom dit in "lump" mode gegaan het. Volgens hulle geen fout met die sensor of termostaat nie. Snaaks genoeg, het die naweek meer as 500km gery en dit het nie weer warm geword nie. Hopelik is die probleem iets van die verlede

    After the repair of the turbo pipe that stop the lumb mode the problem seems to be gone. It's 20000km further and still gone.
    hopefully it stay away
