I dont realy know how to explain this but, my car over heats so bad that the tappets go like tik tik tik tik,
The oil is fine and the water is fine, the water is actualy cold and the engen over heats,now i dont know if its a thermostat and if so how do you go about to replace it?

Re: Renault 5 GTL
Remove the thermostat, put it all back together, add coolant that you have lost, bleed out the air & see if the problem goes away. If the thermostat is seized closed, the radiator will be cold when the engine is overheating.

12th inlet 14 exhaust for the valve clearances ,adjust by the rule of nine that is number one down adjust number 8 -----number 2 down adjust number 7 ---and so so so every adjustment adds up to 9 ,simple when you know how isnt it
Suspect a sticky cam follower/tappet that is hydraulicly adjusted and isn't being controlled properly. Usually adding some additive in the oil that frees up lifters will help, or an oil change using an additive for the same purpose will help. It may even 'go away' on it's own over time. Good luck!
valve guides worn and tappet adjustment required, can check tappet adjustment first to see slightly better before removing heads and getting valve guides repaired/replaced on heads common problem
if raise revs to 1500-2000rpm and hold does clatter come and go come and go (valve guides) if there all the time tappet clearance issue
if there only under load (1st rev up) for a couple of times then stops possible big end bearing
all these are common for this engine
You can try a thicker oil. But it sounds like a valve lifter may be going bad. Try an additive to see if it makes any difference. May be that the pump did not pump the oil right away. Run the car for a while . See how it sounds.If the ticking gets worse it is probobly one of the lifters.
are they hydraulic tappets?? not adjustable but a mechaniics bodge if they are hydraulic ,,,,put a 5 sec squeeze of washing up liquid into oil filler and half a litre of diesel -----run for about 2/3 days without doing any boy racer stuff ,,,drain oil and refill with a diesel grade oil like shell rotella or anything cheap off of the supermarket shelf and refill with this and add some more washing up liquid .run for a couple of weeks then change oil and filter .and refill with a cheap diesel/petrol oil from supermarket and change oil every 6000kms or 5000miles or a least once a year more frequent if low mileage .this should free off the build up of gum in the hydraulic tappets without stripping the engine.expensive oil is well known for causing this as poly methyl methacrylate which is used to hold the oil viscosity has a nasty habit when full of crud from not changing oil regulary to clag up.moral of story change oil often but a filter every third oil change
If it ticks louder than most cars, maybe it is running a little hotter than most cars?
I wouldn't worry about it.
I suggested oil level as low oil level (to almost none) would make the valve tappets noisy.
But your "problem" as you said is when the engine is off, if this is the case then I wouldn't worry about it.
Take your family's advice.
The heat of the exhaust system contracting (cooling) is what you are hearing.
How much mechanical ability do you have? Replacing the head gasket on a 5 is not an easy job, and if you have water in the oil, you prob have compromised the main & rod bearings. Water & oil on the bearings makes them wear out rapidly. Plus, if you take the head off (don't pull it UP, leave a corner bolt in loose and PIVOT the head on the dowell pin, that way you will not pull up the liners), if you don't, you will unseat the piston liner seals, then you have a whole new problem to deal with. If you really want to do this, you need to remove the cyl head, and then take it to a machine shop to check the straightness of the head mating surface, and possibly the block. Then hope that the liner seals are not compromised when you put it all back together...
Overheating Renault engines is unfortunatly quite expensive.
Sorry, I do not have the torques specs.
