I have recently purchased this vehicle- its a 97 Disco V8i 4.0 liter automatic purchased in the US. The troubles I am having that I hope someone can help with:
1- the engine temp rises after a short period of idling, but will reamin at normal temp when driving around, with or w/o AC on... 2- hot water is leaking down from the edge of the center console all down the passenger side of the vehicle - we are talking a quart or more of hot water. the odd part is that i have flushed the system and replaced the coolant with fresh coolant- but the interior "leak" as I will refer to it is pure water. It has done this at normal operating temp as well as when it is runnign hot!-DIAGNOSIS- I have checked the hoses and water pump,etc for leaks and collapsing hoses - found NONE. I have removed the thermostat and tested it in boiling water, it opened up at around 200 degrees, but fairly slowly- I have ran it without the thermostat and have repeated the overheat process- not sure if running without a thermostat could possible cause overheat, but it was just a trial and error thing. The viscous coupling on the main fan attached to the waterpump appears to lock up when the engine is hot, not sure how stiff the coupling should be when it is hot- anyone have advice? Auxiliary fan comes on when running AC, not sure if it comes on otherwise- is it temp controlled?? waterpump shaft appears balanced and not loose. there is only a tiny access hole (1/2") in the top of the actual radiator
-observed no bubbles in the radiator. no yellow residue on the oil cap, no water present in oil or vice-versa...
if anyone can help with these problems or knows a better ng or website then THANKS!! :) appreciate all advice! robbie
