405 Heater...

Nov 30, 2003 2 Replies

Ok, the heater in my 405 never truely seems to get hot anymore? (Mk2 1993



1.6i cat).

If i leave it running and standing, or am in traffic or whatever and get the fan to come on, then it blows pretty warm, but not hot like it used to, and the vents under the windscreen don't ever blow as hot as the vents in the dash!? After the car is nice and warm (not so warm the fan is on), the vents in the dash blow warmish, but the windscreen ones don't....



Any ideas anyone?



TIA



Check the engine coolant level.

Also check she's not oiling the coolant - oily water will block the heater matrix in no time.

Have you ever used Radseal or similar? They're a bugger for blocking the matrix.

Thermostat, or partially blocked heater matrix?
