What engine do you have? One noted problem with the 4 cylinder engines is the reliability that at some point the intake will crack. I went through all the same things when I bought my 93. Drove off the lot, started overheating, replaced the thermostat and still had the problem without moving from the driveway. Look all around the intake. Make sure car is full of coolant and have the engine running. Most likely you will see a small coolant leak on the backside by the firewall. These cars were known for this problem. By the way if this is the problem make sure you take it to a reputable mechanic, make sure you get a new one installed. I had a used one and had the car back in the shop the next day. It then sat there for 2 more weeks while the used car dealer and I had a "discussion".

I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.

hi all i have fixed the problem please note this is for the renault scenic 1.9 dti 1998 reg. i had taken the casing off on top of the engine the one that covers it all for noise meaning the black cover. and looking back to the bulk head to the right hand side you can see 2 hoses which are side by side which are going into the car i dis connected both hoses and got a hose pipe and blasted them into the heater matrix with water (cold) and i dont no if this was a good idea but i got a mop bucket full of hot water reason why hot is because the engine was hot and poured it in to the tank where you top up your water just to fluss the system when it was filling i started the engine then kept pouring the water in when bucket was empty turned engine of asap re connected both hoses. on the LARGE hose you have a bleed screw i had taken that of completly then started the engine to let the water bleed through but again kept pouring water in the top up tank half a mop bucket whilst engine was running i replaced the bleed screw and hey presto the job was done i have not had any heating in the car for 4 yrs but now its hot hot hot. hope this helps to all with the scenic

I'm not particularly familiar with that vehicle but all that I have seen also have a valve that opens and closes to allow or restrict the fluid flow to the heater core. It could be a problem if you haven't already eliminated it. The air defecting doors under the dash that direct air to the floor or to the defroster are also suspect.

You just might have an air lock. Try bleeding the system from the heater hose at the firewall. Losen one hose a little, and at operating temp. open slightly to let air out. You will lose some coolant, but just refill the rad. Now, both hoses should get hot.
