clio heater

hi i have a 1991 clio 1.4 rt
and the heater just does not get hot at all in the car i have changed the thermostat could it be anything else or is it just possible that the new thermostat could be faulty or wrong temp range
please help as the winter is now here it is horrible to drive with hat and gloves on
many thanks

if no bleed niples fitted,remove right hand heater pipe.(looking under bonnet.) start eng and let water run out until no air bubbles.keep topping up water!

tried removing heater pipes etc... to remove air
it hasnt worked all the pipes are getting red hot and doesnt seem to be any air in the system is it worth trying the thermostat again or you think it may be a blocked heater radiator

if both the heater pipes are hot ,the water is flowing through the matrix.check to see if the flaps inside the heater are opening,

well it looks like the old clio might have died (RIP) It started leaking water bad from behind the exhaust manifold area at the weekend i removed one of the exhaust manifold bolts and the water was coming out from behind them think the head gasket may have gone now someone said could be £500 upwards so might scrap it now seems a shame its a lovely little car
does it sound terminal to u ?

possability of a core plug rusted out,realy hard to tell,but further stripdown should tell.

I have a Renault Clio 1.2 Oasis - the Heat inside the car is at best Warm.
I have changed the thermostat, changed the water pump, flushed the system through with water, and with radiator flush, but it's no different.
The only time I can get HOT air through is if I run the car for a while with the FAN blower Off, then switch it back on - then I get about a SECOND of hot air.
This to me suggests that the water isn't circulating - but as I have said earlier, I've changed the water pump and flushed out the system ??? Can anyone help. dylanpugh@usa.net
