V8 over heating

<< < (5/6) > >>

Henry Webster:
Me neither! :wink:  I guess I shuld shut up, then!

I have the same drinking problem! :lol:

Range Rover Blues:
:lol:

My solution, get it to drink something cheaper.  At least it's not noticeably worse with the caravan on.

ok im getting very worried no as, is still over heating and im worried i may be damaging the engine......


i had another attemp of trying to sort it out yesterday, buy cleaning every bit of dirt off the radiator, flushing the system out and refilling it, toping up the oil, and i even took off the plenum chamber to see if there was a blockage in the cooling pipes..... gave it a good cleaning aswell, as that camber had abit of oily crap in it.......

thought everything was working and that i had done it, then suddenly it got hot again  :evil: !!!!!!!

ok im sure its not the cooling system anymore and that its more an engine problem now.....  all the fans work to try and stop it from over heating, well not to sure if the viscus is working properly but its always spinning so cant be that bad, and also it has always bin the same and it didnt over heat then!!!!!!


today it wasnt running the best ive every seen it, as when i first started her up the revs went to about 1500 as she usualy does but instead of falling straight away it took several seconds to drop, and then it was done in stages..... also when driving today it doesnt want to idle very well and feels like it missing a cylender or something as it shaking abit, and then i hear a knock that sounds like its coming from the exhaust (or could even be the bottom end :shock: ) ..... it use to idle at about 550 RPM when in drive and about 625 when in neutral, but now after driving abit and then pulling up to a stop it will idle at about 675 then take some time to slowly drop!!!!!!!!!!!

another thing i have noticed to day was, when i pull up to a stop and it feels like its missing, i have to press the break peddle abit harder to try and stop it moving, as it wants to try and move forward but in pulses (like on a certain power stoke of one clender...if you know what i mean)


to day the engine was apsolulty stinking hot, and was near impossible to open the bonnet, but the cooling system wasnt overheating yet, and was at a normal temperature..... its as hot as it was when the vaccum advance wasnt working, but ive looked at that and thats fine.... im sure there isnt another air leak!!!!!!!

the thing is the car runs great when on the move and has loads of get up and go


does this ring any bells for anyone..... im trying to describe it as well as i can!!!!!

Range Rover Blues:
The engine is hunting, that's why it creaps forwards in drive, don't worry about the box it's a symptom of the fast idle.

If it's misfiring there could be a running problem, an air leak in the inlet manifold, a clogged injector etc.  Keep an eye on the oil quality too, if it look cooked you have aproblem, run it on the thickest/best you can get in this weather.

A misfire could give you that knocking sound.  I accidentaly folded the top on the inlet manifol when re-nstalling the inlet and it gave me an air leak on 3 cylinders, some similarities to what you have described too.  Try a vacuum check on the engine at idle.

disco-v8:
so whats the best way to do a vacuum test?????


and also what sort of code read can i buy to read my ECU which is alot cheaper than yours lol?????
