Question about 1999 BMW 318 ti

2 Answers

OVERHEATING!!!!!!! my car began overheating on a 6miles in to a 8 mile drive, it had a small crack in the rad' which i changed the next day, i bled the rad' ran the car again and it overheated. So far i have changed the water pump, thermostat, all water pipes, taken the head off, had that skimmed and pressure tested, new head gasket and blocked off the heater matrix to eliminate that from the coolin system and still it continues to overheat, it looks to have poor circulation as pressure builds up in the rad, pipes and hoses after 5-10mins of running and can be seen rising in the expansion tank!! is there anythin else u can think of that i may of missed????

Ilragatzzo78 is 100% right.  I had the same trouble with my 318ti.  It took a lot of sitting on the side of the road.  The only solution is time.  Bleed, bleed and re bleed.  You can bleed it through the bleeder screw on top of the radiator (plastic screw).  I didn't know about the angle part, but thanks for the idea..

Nooooo.
that's the problem
yes, you have to take the coolant filling cap off " expansion tank cap "
turn your car on for at least an hour
the bmw line has a very bad problem wich is " bubbles " inside your water system
you have to have your car inclined and running without the cap so he can bleed all the bubbles out.
sorry you spent all that money but after you replaced the radiator all you had to do was that, to get rid of bubbles.

so, do this. park your car on an incline position, engine up.
remove the cap. let it run for at least an hour.
refill as needed " coolant "
do that the following morning and for last refill the collant as needed.
problem should desapear.
hope this helps

I have a 2001 nissan sentra 1.8 with 158,000 miles. Problem started a month ago,no heat while idling but when revved up or driving would have heat. Changed thermostat,bled system from bolt above thermostat...


unfortunately these engines are known for this condition and for head gasket failure.with engine cold pressurize cooling system with spark plugs removed.look down into holes with flashlight after about ten minutes.....im betting youll see a puddle of coolant on piston...usually its cyl# 2 or 3.i cant think of any other possibility for system repeatedly airlocking other than a head gasket.good news they are probably one of the easier ones to replace.

Car is overheating when when driving for around 15 to 20 minutes. if car is thrown in neutral when driving the temperature drops immediately. thermostat has been replaced and system has been bled properly....


Is it overheating to the point of boiling over, or does the guage or light just come on? What i am suggesting is that maybe it's the heat sending unit, or temp. sensor that is faulty. If the thermostat is working, the water pump is working, the coolant isn't low, the fan cuts in and out, and the rad isn't plugged, i would almost say it has to be the sensor. Let me know.

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

2002 chrysler 3.5 overheating - new rad, water


It can a the first stage of blowing head gasket.

Fill your coolant tank to the full mark when it's COLD.

Start the car, and pay close attention to the tail pipe for a small puff of white smoke.

After 15 minutes,If you do see any vapor then take the car for a 8 minutes drive.

Park the car and listen for bubbling sound from the coolant tank,

If you see bubbles coming up then you will need a head gasket change real soon.
