Possibly a split hose or loose clip?

 

Or a faulty radiator core, i've had mine replaced and I know i'm not the only one.

 

as above a few members have had a problem with the bottom of the radiator core I think, I know Paul R26 has, get it back to renault your lucky you bought it at a dealers and not private?

make sure you do a pre check sheet mind to check nothing happens to it while its in!

 

Thanks for the suggestions guys a loose clip or a split was my first thought, but this would surely fail the pressure test? There stands a good chance that the rad could be at fault, as the loss of fluid does seem greater when the engine is up to full running normal temp, this is also when the rad has greatest flow through it.

What seems to be the issue's with the rads? do they rot from the inside out? or is there a part to blame? I know the warranty covers the rad, but it sure wont if its a stone that has damaged it

 

It's where the core meets the plastic end on the n/s ive done about 5 rads for this

 

mate pressure test the system when the engine is at optimum running temp and you should find your leak

 

Well i have found the leak now, seems to be from the top nearside corner of the rad. Only problem i have had now is that the warranty company doesnt want to pay, even though a Renault specialist diagnosed the problem! The main dealer want the car back to take a look as they say the warranty will cover it. The problem is that its £200 for recovery back to the dealer & then it might be alot more if they decide the warranty wont cover. I guess then i have to pay from what they have said. Bad times

 

drive it back

 

I think i will just drive the car back once i have had it fixed, & dump the leaky rad on them with pictures, bill and say that they have to contribute something towards

 

Had the fixed back in October with a brand new genuine part fitted and supplied by the Renault specialist i use. The Renault garage where i bought the car from approved the fix and so did the warranty company who paid the bill.

As of yesterday i now have coolant leaking all over my garage floor and the rad seems to be leaking AGAIN! From what i can see it is leaking from the top nearside corner AGAIN!

Has anyone else had a similar problem? or am i just that unlucky, and need Two rads in 6 months?

 

Oh dear I think someone else had problems on here Renault parts warranty will cover the cost

 

That sounds really unlucky. I went to Fastrads for my replacement rad. Just hoping it's gonna last a long time, but at £57, it won't break the bank . You'll see my post on it - Bird Strike - it's got a different core design.

 

It seems that part of the shrouding of the fan, that supports a intercooler pipe was broken causing the pipe to hit the rad.

£58 New fan shrouding
£164 New rad
£200 labour

The above which iam having to pay as the Renault dealer has refused to help me eventhough the car has 6 months warranty remaining

 

Whats their basis for refusing?

 

Well, here's a story for y'all.

My car came home a couple of days ago and proceeded to piddle all over the concrete in our carport. The liquid was thin, but felt slippery. Had a sweet smell (kinda like very weak honey/golden syrup) and disappeared quickly, so figured it was coolant.

The expansion bottle took about 3 litres :shock: so it was quite clearly a significant exodus. Had a look around and followed the splatter pattern back to this little blanking plug:

The temporary fix? Yep, two hose clamps. It had perished and split, and I figured it was slowly (or not so slowly) squirting liquid into the back of the engine bay.

My coolant is now very dilute, and I'll have to replace it as soon as this is all sorted.

Doing some digging, I also found what I guess is the bleed point for the cooling system:

which hides down behind the engine, battery/ecu, air intake and is right next to the brake booster. It's just visible in the next picture too. Can anyone confirm if this is the case?

So, the next step is to find a plug for the one that's failed, and replace the coolant. Fun times opcorn:

 

Part number for that plug is 8200293992. And thats one bleed screw the other is a bolt on the thermostat housing not far from the plug, you need to ensure an air run of coolant from both of these before bringing the car up to temp to complete bleeding.
