guys i have got a big problem with my reault 5 gt turbo.
whenevr im drivig, i hover heat!

God! Did you send this by text message? ;-)

If you're overheating it'll most likely be a problem with the cooling
system. I presume you have the coolant topped up properly?

Does the electric cooling fan come on when the engine is hot? If not it
might be worth investigating the fan fuse, the fan thermostat, then the
fan itself, then the fan wiring.

If it does, then the water system may well have a fault.

Before looking at expensive options, check that there are no air locks in
the water system. I believe the Renault has bleed valves on all the top
water hoses. See if you can let air out of these while the engine
running. Also give the hoses a squeeze while running to try to force air
bubbles back up to the header tank.

If it's not air in the system then my first suspicion would be the
coolant thermostat (that redirects cooling water through the radiator
once the engine is hot).

Second suspicion would be the water pump.

Then you'd have to start looking at the possibility of a silted up system
with sludge blocking the waterways in the engine or the radiator.

Hope this helps,

Rich
