towe001 Posted March 3, 2011 Report Posted March 3, 2011 Have you tried the timing ? Whats the weather like in your part of the world ?Just an average nice day or just crank the air con and stay indoors ? How fast does it overheat ? As fast as it would be to make a cup of coffee or would it take a while ? When does it overheat ? Around town or on the highway (or at speed) ? How long does the battery charge light stay on for ? Goes out as soon as the motor gets kicked or stays on for a while and its on and off at times ? The weather can play a part in the operating temp. Over-advanced ignition timing can drive the temp up - Try timing the motor. As can a blown head gasket - Compression test. Overheating around town could be a blocked radiator or at the least a blockage somewhere - Radiator shop and get it pro-flushed. On the highway it could be the water pump. (I think those two are the right way around) Battery charge light could be a sign of the belt slipping. Another one is bad hoses. Soft is bad, you need them to be nice and firm when you squeeze them between the hand and have a look for cracks, splits, bubbles etc (their bad) 1 Quote
altezzaclub Posted March 4, 2011 Report Posted March 4, 2011 That's a pretty good list Towe.. Sinister there is a thread called the ultimate overheating thread or something like that- Why pull the head unless the gasket is blown? ..and if you haven't confirmed its blown do that first. First symptom is a car hard to start in the morning first time, then fine all day after that. (water leaks into the cyl as it cools at night and condenses on the spark plugs) Crude test is- one morning before you drive it take off the rad cap, full the rad right up and then start it. Let it idle while you watch the water level. If it bubbles over the top before it warms up you have compression being pushed into the radiator through the head gasket. Professional test is a leakdown test at a garage or the test kit that shows exhaust gases in the radiator. Jets would show problems in other areas. Blocked idle jet means car wont idle, blocked main would mean car coughs, lacks power, or won't run above a couple thousand RPM, blocked secondary means car won't run up top. A bit of shit in a jet would run it lean, which would overheat it, but it would be so bad you would feel the lack of power. Overheating- radiator blocked or cores had it, thermostat jamming, motor water channels full of shit, water pump knackered. As Towe said, retarded ignition leads to overheating. So now we heve educated you, you can go and find that the points need replacing and timing resetting! :laff: Quote
SinisterRolla Posted March 5, 2011 Author Report Posted March 5, 2011 Haha ur a couple of legends cheers for that :D yea I'm in perth and the battery charge light does stay on for a bit but it starts and runs fine and its defo overheating in the time it takes to make a cupa il hav a play about and see what works.
