Right where to begin... Cars been playing up the last few days, wouldnt start so got a new battery, fitted it and it starts all the time now. But, only for so long... read on. Yesterday I was fiddling round and noticed some green sludge under the bonnet, all round the intake and bulkhead - put this down to a CV rubber being split and its just sprayed it everywhere! Now my main problems are, the belt off the Alternator has been squeaking since I bought the car, WD40d it up and it went away but now even with the new battery the charge light is on constantly. So I guessed the alternator was fucked but after actually looking at it, the belt has either snapped or fallen off!! So my question is what else runs off that belt? Reason being, my car is now overheating (can hear it bubbling like fuck from the expansion tank when stopped) and the dial reads anywhere between half and off the top of the scale. I was just wondering if this lack of alternator belt would have something to do with it?? Heaters are cold as well - did this on the way to work the other day but suddenly dropped down again and started blowing hot about 3 miles down the road. Thermostat? Or worse?? Fan is constantly on too. The whole time Ive had the car the temp gauge has only ever gotten about a third of the way up the scale, even when driving it hard.
