the problem is when the engine is warm the heater is only luke warm, all pipes under the bonnet are hot, the heater box is hot down the right hand side, but the heater is only blowing warm on the first speed, if i click it onto speed 2 or 3 it blows cold,

cheers, neil

cheers for the mega quick reply matey, will call and pick up a new one tommorow

Maybe a build up of gunk inside your heater matrix. give the heater matrix a flush out as this can stop water passing it properly.

neil73

will try that too, will a rad flush be ok or will it need the hose treatment?

louie1

The hose will be fine just remove both hoses from the bulkhead and wash it through both ways. you may get a load of brown water come out if its bad. just dont have the hose tap on to hard, gently does it ok!

cheers matey

fushed it through tonight and water was clean, still have the same prob so will change the stat at the weekend, is it best to buy a gen one or will a pattern part be ok?

Robs Frst

gen, or pattern should be fine.

what temp does the car run at, also will it go up and the rad fans cut in ok. does it even have a thermostat in it?

neil73

the gauge sits on m of 'norm' (the fan kicks in between m and r) and when i drive it drops down between the solid white block at the bottom and m. defo got a stat in there, saw it when i did hg last december. you can see the water swirling around in the header tank when its warm????????

louie1

check that the feed and return hoses are hot and if thats the case try the lever that changes the temp from hot to cold on the heater box is not stuck/playing up!

neil73

will do, cheers matey

neil73
