    My wifes car has a leak. It's not going to cylinder head as there is normally a puddle under the car after parking. Where is the drain point for the system. I assume it is at the bototm somewhere but I haven't had a chance to get under and have alook around. Only going up on a trolley jack so hoping it's not too hard to find.

    i have a renault clio 172 sport (2000)....


    i noticed that my car heaters dont always blow out warm air even when i put it on the hotter setting, soon after my car started to overheat and i could see by the needle on the dash, i looked under the bonnet and relized that the coolant levels were bellow -min- , ive added water but it seems to just gulp it down like a dehydrated person...


    the levels are not maintaing between -min- & -max- i'm worried that my car might overheat and cause alot of problems.......


    can someone please help me to find out what is wrong with it because i don't really understand the whole entire problem


    thanks matt

The head gasket on the R 5 is aluminum,Just see if your oil is like turning a white colour.
if not then its not the top gasket and you can check the water pipes,even a small leak can cause this when the water heats up and build presure so you dont see it coz your driving.

also check the water bottle's cap if it seals properly,you can loose water from steam too...

Hope this helps...

Do the checks as above (check oil for water contamination - white residue etc ) But if there is a puddle under car after stopping and you can check this by putting down cardboard or newspaper under engine, then most likely fault is the water pump or pipe leakage. I solved my water pump leak by adding a stop coolant leak solution that can by purchased at any car parts shop. Still working after 5 years - though I carry a spare container of the stop leak solution and a litre of colant as a matter of course.

This is valid for cooling systems in general, especially on Renault models where the water reservoir is in the flow path, as on eg the Clio, as distinct from models where the reservoir water only flows into the system for top up.
The actual rate of water loss is quite critical to the solution. Also whether the engine tends to overheat, even a little, when under stress. If it does, then assuming there is enough water in the system for functioning, look for a head gasket problem. Don't overheat badly or for too long, it will quickly accelerate the problem to a crisis.
Check extremely carefully the possibility that the head gasket is slightly blown and drawing water into the head in small quantities, or sending gas into the water and pressurising it, which would cause persistent loss through the water reservoir pressure cap.  Small water loss into the oil won't show because the engine burns it off. Suggest you run engine, then undo water bottle reservoir and rev the engine slightly. Look for bubbles and if there are any, sniff for exhaust smell. Look for unexpected discoloration of the coolant water.
If your engine passes those tests then water may be leaking away from a hose or from a fracture of the bottle, especially at the base.
If there is no identifiable leak or loss mechanism then either you've missed it or water is going into the engine in small quantities. Watch the situation very carefully for signs of change. These engines are quite robust and will go for a long time in this condition without blowing up or suffering any serious damage, but eventually the gasket will blow properly and you may be looking at buying a new cylinder head. You can get them for £100 to £200 on the web, but the main problem is being stranded.

If their is no visible leak then it must be the head gasket. Does your car overheat? Coolant has to go somewhere since its a liquid there's nowhere else for it to go. If I am not mistaken, Renaults have aluminum heads and have a history or warping causing the head gasket to leak. get a 2nd opinion

Renault megane scenic coolant loss


A small leak in the head gasket will cause the coolant to disappear,but will not always be visible steam from the tailpipe.(small leak).A good way to check for this is to remove the spark plugs(keep them in order),and see if one of them is cleaner than the rest.(The coolant will steam clean the plug,and leave a slight greenish hue in some cases).If you do find this,you're looking at doing a head gasket.

I have a renault clio 52 reg, the engine coolant keeps goin down


i have a clio, had same problem too. its the head gasket. when this breaks or cracks it allows water into parts of the engine it should not, and therefore the water starts to mix with the oil forming this 'light brown gunge' the problem is that when driving with a damaged head gasket you will damage the head of the engine too which is why this is reoccuring. your best bet is to take apart the engine, clean it out, buy a new head gasket and then get the head of your engine skimmed. this could solve the problem depending on how damaged your head is.

I have dirty water getting into the spark plugs of my 1993 renault clio 1.8 16v. what is causing this problem?


What happen at some time or another your engine got hot, now the head gasket is damage and letting water go where it should'nt. The only fix for this is to have your head gasket replace and the cylinder head check for crack's and resurfic, also they'll need to fine out why it over heated in the first place . Good luck
