Hi all

 

Despite my Clio having been the most unreliable car I ever owned, for some reason I decided to buy another Renault and got myself a Megane. The starter motor went after a couple of weeks and now I have noticed I'm losing coolant.

 

I don't think its the gasket as I can see it dripping underneath but i cant easily see where its leaking from, also since beeing topped up, I'm not convinced it's even circulating now.

 

Any ideas?

Get some of the uv dye stuff and a lamp. It's great for highlighting leaks. Hopefully just a dodgy clamp

Roughly where is it leaking from?

 

Under front bumper?

Drivers side of engine - inline with wheel?

Sounds spot on for water pump area. If not circulating as you suggest, then it could be the pump.

 

Not knowing the age/engine etc, the older meganes also had a "flange" hose fitment on the block with an O ring which was known for leaking.

 

Never had any engine problems with our 1.5 dci megane (2008) but we did have the electrics issue (injector fault on dash, resulted in a new circuit board being fitted was the main one, but we also had issues with the rad fan running all time which was caused by a corroded connector on the air con switch. Had to cube mod 2 window regs and fit one new window reg motor in the 3 yrs we had it.

thanks, its an 2005 1.5DCI, l try taking another look. 

 

My Clio had rotten electrics and that was before the fuse box corroded, the air con never worked and eventually the injectors went.

 

I've only had this a month and the starter motor went, it took me an hour to change the front headlight bulbs due to the stupid access through the wheel arch (who designs a car where you have to remove a wheel to change the lights) and I have water in the passenger door side pocket which I thinks due to the missing wheel arch cover....

 

I have a horrible feeling of Deja Vu, I think Mr Haynes and I will be getting reacquainted. Shame really as otherwise its a nice car to drive

You can do headlight bulbs by turning wheel, but yes, its still a terrible design.

Unfortunately the housing snapped when I tried to get it out leaving the metal connector stuck inside, so I had to take the wheel off to get enough leverage with the pliers to pull it out..happy times

oh dear, happy motoring then..... :/

 

A coolant pressure tester might show the leak or at least help finding a  rough path from where it comes from. Most garages have these, you basically pressurize the cooling system which forces the leak to show. If water pump, you might not see it directly due to covers, but at least it might show it dripping from the timing case etc.
