I NEED HEAT!!!

(1/4) > >>

whitewolf:
Ok, I have to consult those wiser than me once more.....

.... I nearly got frostbite yesterday morning, all blow and no heat from the hearter!

Now I have already flushed the system, and heater matrix, in both directions,and water is clean and flowing freely and a new thermostat has been fitted. But she still only gets just past the quarter mark on the temp guage and there is naff all in the way of warmth worth mentioning comming out of the vents. :?

And ideas people??

A very warm thanks in advance

L90OOK:
How far are you driving?  Is the journey long enough for the engine to warm properly?
Did you bleed the system properly when you flushed & changed bits?  The heater is the hardest to bleed :roll:
What is the coolant level now?

Evilgoat:
It depends on what you are driving.

V8 should be able to cook chips on the dash after about 5 mins :)
200TDis seem very variable. Serenity is 'warm' after about 3 motorway wiles and hot after about 10. Roo (Datalas's Motor) Takes about 30 miles to get to 'marginally above freezing'

Check water levels, bleed the system, check your thermostat isnt stuck open and bung in some antifreeze (yes this will help)

I've had the idea of removing the engine fan and going for a Kenlowe suggested as a means to raise the point the fan comes in a little.

Not sure about 300TDis

whitewolf:
The journey is 15 miles with some good hills to get things working.

Spent ages bleeding the system through both the top of the rad and the header tank,the water running from the bleed plug on the rad was free from bubbles.
 level is currently high in the header tank.

L90OOK:
Is the top rad hose getting hot?
If not I'd suggest the thermostate is stuck open.
What engine is it?
