Over Heating / Radiator Water Level

[Donkey]

Hi everyone,

Need help asap. i have a 95 aristo and had the water changed as it is a new import. The problem is the temp gauge rises then drops, rises a bit higher then drops and so on. it spits water/coolant out of the reseviour tank. Can anyone help????? someone told me that aristos run a bit lower in the main tank. Can anyone help.

Many thanks,

Hate to say it but it sounds like a cracked head- the system's being pressurised by the engine compression. Could be a head gasket instead- is the water milky looking, and does the oil have a milky/watery top layer?

No oil in the water and no water in the oil......... it's like there is a air block on the sensor... If it was the gasket wouldn't the heat just rise? this rises and drops...and so on.

Oh dear. Better be careful not to overheat the engine. If overheated, it will cost you a bomb to do overhaul!

maybe have a poke around and check the thermostat too
