Rusty coolant water.
Rear brake cylinder replaced
Heater matrix replaced
Back offside door leak.. swimming pool effect.
Usual 'Renault service tool' nonsense to deal with when working on the car. This can be a major pain in the ass.
Back off side door leak appears to be related to the inner membrane being ripped by some asshole or another. The rear seat covers are handy to wash in the washing machine if you care to spend a wee bit of time taking them off. Use small cable ties to replace the metal fastening rings if you do.
Quick off the mark seems eager enough.
Could do with a rear internal light/
The rusty coolant water is due to a high zinc content in the radiator and heater matrix metal. This is why the proper Renault coolant is recommended.
I replaced my rusty water with this and it's been fine, though it cost £40. This stuff isn't cheap.
Will the rusty water damage the engine?
