heater problems (newbie)

[gonzo94]

hi,i have recently purchased a 96 corsa trip 1.2 8v,the heater works but not to its full ability.i have changed the thermostat,flushed the cooling system with a small caustic solution,the amount of crap that came out was not surprising,the previous owner had no mechanical know how,since i have done this action my temp gauge hardly moves of the lower mark,i have made sure that there is no air-lock in system,just does'nt give out much,any suggestions please.

Does the gauge go up in traffic but the comes straight back down when on the open road?

[gonzo94]

yes it does,is that common,most of my cars have been vauxhalls,cavs,omegas,carltons etc,but allways great on the heaters.

heater matrix possibly had it

[scotty cav turbo]

yes it does

If it does that then, the thermostat is stuck open.

brand new one fitted last weekend,even tested it in a saucepan before fitting,us plumbers do strange things!!!

Is it the gauge or the heater inside the car thats the problem.....

[gonzo94]

all the vaux's that i have had over the years,the heaters have been spot-on,gauge hardly moves and it struggles to give out any real heat.

i have just had a brandnew x14xe engine in my car and mine did the same thing

jusst leave your car running to let the temp go up nuntill the fans kick in

do this 3-4 times and it sorted mine
