My car is overheating and there is a bubbling water noise in the front, what could it be?

Check your oil dipstick. If there's a grey/creamy sludge on it that means water is finding its way into the oil system. Your cylinder head gasket/cylinder head is faulty.

Fill your coolant bottle. Leave the top off. Start the engine and watch the coolant level. To begin with, you will see air bubbles escaping. This is normal. If bubbles continually appear or the coolant level 'shakes' violently, this indicates that exhaust gas is finding its way into the cooling system via a cracked cylinder head/faulty head gasket. Also look at the exhaust gas - is it clouds of white? If so - that's steam from water being burnt in the engine - a head problem.

Over heating is a sign of a cracked cylinder head/faulty head gasket.

The other causes of overheating includes a stuck thermostat or a leaking/blocked radiator.

If there's no sign of a coolant leak underneath your vehicle - suspect the cylinder head gasket

Have the head gasket checked, it sounds like it needs replace.

white smoke is caused by-- water or anti-freeze entering cylinder . if in radiator or the overflow tank. it will look like a chocolate milk shake. check on oil dipstick for traces of water or anti-freeze. also, a bad head gasket will let water or anti-freeze in combustion area. head gasket symtoms if bad. Symptom #1: Chronic Engine Overheating
Symptom #2: Significant Drop in Coolant Level Symptom #3: Mixing of Coolant and Engine Oil
Symptom #4: White Smoke from Exhaust Pipe
popping of overflow cap Symptom #6: Air Bubbles in Radiator
Symptom #7: Engine Lacks Power GOOD-DAY!

First off, there is a number of reason why u are hearing bubbling noises but first lets address your Fan. I take it that u have a 2 fan setup, when you say " The passenger side cooling fan will not cut in". This fan is associated with the AC, and only comes on when the AC runs. Helps with better air flow thru the condenser which is in front of the rad. Does the AC work?

OK, now for the bubbling noise. First off the noise indicates to me that maybe you still have problems with over heating. Does the fan on the drivers side come on? Where is the Temp gauge at when it does come on? You might have air in the system, which canbe bleed thru a bleeder screw on top of the motor. I found the best way to do this is have the frt of the car elevated abit with the car off when filling the coolant reservoir. Other things associated with over heating, thermostat not opening, or stuck open. Head gasket, possibly exhaust is getting into cooling system, building up pressure which vents when you shut engine off. Hench the sound. Water pump possibly leaking.

i Just fixed a problem with a renault megan washer motor. If the motor makes a noise but is not pumping any water & the jets@ the windscreen are clear, then pull the suqirter motor out off the washer bottle( the bottle stays in place ) it just pulls out from underneith the bottom stone tray& may need to remove bottom bolt, inner lower wheeel arch. Right Now where the black & white squirter come out of the motor gentlywith a screw driver pop these off together. ( test motor again) ( put in water ) Then with Snap ring plires & part the white & black outlets apart & you will find a rubber seal that looks like it must of grown. When it grows it blocks both ports off. you need to shorten the rubber & keep it flat as remember its job seems to block off either the front or rear port. if it not a good finish you may get water coming out of the front & the rear ifeg your working the front squirters

people across the world sit down in front of tv and watch rally cars go through there paces,but remember these cars are not the cars you in your local showroom.The things you describe i could tell the same story 1000 times over you are not alone plus you purched the car in 2001,and i dont know /but the local vicar owned it?????.i have said it before this engine is an old renault 1900cc,engine it never done renault any favours infact quit the oppisate download.adrian;;;

Normally it is the head gasket not the manifold gasket that causes overheating, it does it by cracking and allowing water from the coolant system to be blown out of the exhust or get dumped into the sump.

When you start the car is there water coming out of the muffler

If not then dip the oil , is it like a thick chocolate milk shake

Final check is to take the cap off the radiator or header tank and see if there are lots of air bubbles coming up.

Any of the above means a shot head gasket

Fan shaking? not a good thing... you need to find out why...fan itself or water pump...change whichever is bad.

Was the car using much coolant before you forgot to replace the coolant bottle cap?

The clinking noise you describe - that may be 'pinking'.. a noise caused by an incorrect air/fuel mix .. and also a symptom of a blown head gasket. Another symptom of a blown head gasket is white smoke (steam...) from the exhaust.

First, check your engine oil on the dipstick. If the oil is a creamy grey colour this indicates a blown head gasket. The creamy grey colour is caused by coolant finding its way into the oil system.

Fill up your coolant bottle with coolant. Leave the cap off, and start the engine and let it tick over for 10 minutes. As the engine warms up air will escape from the coolant level - keep topping up as necessary.

Keep your eye open for extreme bubbling in the coolant bottle - violent bubbling in the coolant bottle is caused by exhaust gases finding their way into the cooling system via a defective head gasket.

If there's no violent bubbling, replace the coolant bottle cap when the engine has ticked over for a few minutes..

... and then begin to look for leaks as the engine ticks over. Look under the car to see if there's any falling fluid. Check around the radiator and the hoses. Check that the coolant bottle itself isn't leaking.

You say your car isn't overheating - that's a positive. One symptom of a blown head gasket is overheating.

However, your coolant is going somewhere and you should try and find out where ... If it isn't a leak from somewhere, it may well be the head gasket.

Prices? To have a cylinder head gasket fixed costs around £500 - £1000 British pounds. A coolant bottle costs around £30 (look on Ebay)

If the head gasket is leaking/defective you can try a modern sealant/repair, which I am told are now quite good. Have a look on Ebay:
