After so many over heats.a car sometimes cant handle. after constant over heating your cars rubber gaskets could have gone bad and turned brittle letting in oil into spark plug well #1 for your spark plug problem i would recommend changing your valve cover gaskets. and for the over heating and not turning on. i believe you blew a head gasket.
REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF CAR OVER HEATING WHILE IN MOTION.MORE LIKELY ITS THE THERMOSTAT,LOW COOLANT IN RADIATOR OR COOLANT SYSTEM,BAD WATER PUMP,WATER PUMP WEEP HOLE IS LEAKING, WATER PUMP NEEDS REPLACING.CHECK ENGINE OIL,IF OIL LOOKS LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF CAR IN PARK AND OVER HEATS WHILE IN A LONG TRAFFIC LINE OR.BANK DRIVE THROUGH COOLANT FAN NOT TURNING ON, BECAUSE THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.CODE SCAN CAR FOR FAULTY COOLANT FAN RELAY OR FAULTY PCM. CHECK COOLANT FAN FUSE, AND HOT WIRE THE COOLANT FAN TO MAKE SURE ITS WORKING.IF COOLANT FAN DONT WORK WHEN HOT WIRED. COOLANT FAN NEEDS REPLACING. REPLACE BOTH RADIATOR HOSES, REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.BUY NEW COOLANT ADD 50/50 WATER AND COOLANT.IF ENGINE OIL HAS ANTIFREEZE IN IT.REPLACE ENGINE OIL AND OIL FILTER TO KEEP FROM LOCKING UP THE ENGINE.GET CAR FIX.DONT KEEP DRIVING IF IT KEEP OVER HEATING,ENGINE DAMAGE WILL OCCUR.I HOPE INFORMATION I GAVE YOU WILL FIX PROBLEM.PROBLEM COULD BE LEAKING RADIATOR HOSES BUT CHANGE THERMOSTAT THATS FIRST THING I WOULD CHANGE BECAUSE IF IT CLOSED, ENGINE WILL OVER HEAT AND CRACK CYLINDER HEAD OR CRACK PISTON, COOLANT NEED TO CIRCULATE THROUGH THE ENGINE TO TAKE AWAY THE HEAT FROM ENGINE.
over heating can be caused by a number of things. your water pump could have died or the gaskets could have went on the water pump spilling your antifreeze every where. in which case you need to replace the water pump and gaskets. when you change the water pump you should replace the thermostat because they usually fail at the same time. your thermostat could have locked closed. in which case replace the thermostat. i recommend getting a fail safe thermostat so when it fails it gets locked open and then the car dose not overheat. your belt could have broke so your water pump wont turn. replace the belt. your radiator or hoses could be clogged with rust and sediments in which case you need to flush your radiator and change the anti freeze. you may be just low on anti freeze... so fill it up and see if it leaks anywhere. your tubes could have came off, be loose, or cracked and leaking; so replace or tighten them. your radiator could have a hole in it or leaking some where.. replace radiator. if you drive on dirt roads a lot the radiator could be full of sand and dirt could be full of mud if taken off road. just rinse the radiator out with soap and water. are your floor mats full of water or antifreeze? you could have a bad heater core. replace heater core. or you can cheat and take the two tubes off the heater core and splice them together. (which will leave you with no heat). your fan may have gone out so it wont cool the radiator. the last thing i can think of is very low or no oil in the motor. top off the oil.
Hi, i would check the thermostat first unless the water pump is leaking
as the water pump is where the timing belt is is the timing belt needs
removing to get to the pump, take the thermostat out and place it in a
tub of boiling water and check if it opens up if it dont then it will
need replacing.
you need to bare in mind that it could also be head gasket failure so
make sure you get this tested if the thermostat is found to be in
working order.
Hi having no heat would suggest the thermostat is stuck closed and will need replacing, how ever the really bad news is that if you dont see any water leaking onto the floor or around the engine then this points towards head gasket failure, the thermostat failing would have caused the engine to over heat and this would have caused the head gasket to fail.
Have a good look for a leak as this is the cheapest solution, make sure you check all hoses and rad for signs of water leaking, if you find no signs then the only other way you could lose water is via the head gasket, if you cant see water leaking then it can only be going into the engine, either into the oil or being burned out through the exhaust.
check you oil level stick for signs of a white substance if you have this then the water is getting into the oil via head gasket if the oil looks fine then the chances are the water is being burned off in the cylinder.
let me know how you get on or if you need further assistance ok
if it is the head gasket there will be coolant in the oil or oil in the coolant, I would check to make sure the electric fan is operating, could also be a stuck thermostat or clogged radiator (both of which are MUCH cheaper to check and repair than a head gasket change.
First find exactly where the water comes from. broken hose or hole in radiator - if no leaks here then :- broken / loose drive belt to water pump - sign is no heat to internal heater thermostat stuck - heats up and overheats quickly. water from exits rad cap area also check radiator cap - should be sprung to contain water under pressure, usually these are very reliable
check oil filler cap [inside of] - should be oily and grey/black If it has a covering of what looks like soft brown aireated jelly then possibly hear gasket or other internal engine leak between water & oil ways. The excess pressure from engine will force water out of rad cap area . A compression test with variable readings for between cylinders will confirm this. Hope its not this. It's expensive
There are two slots in the valve cover right by the cam shaft sprocket that have to be honda bonded or black rtv. look closely at the valve cover right above the gasket underneath the timing belt cover. Hope that helps.
even after gasket replaced
