Hi guys

Right here i go hope i come across understanding (woman):eek::lol:...the problem with my 156 twin sparkis that i can only drive maybe 2-3 miles before it completely overheats. The interiour heating system is blowin out cold air..and the temp gauge goes almost within 10mins to red...:mad:I previously had a problem last month with a hose being badly damaged do to wear and tear, which left me with losing water by the bucket loads out of the water tank. Me stupidly just kept filling the water tank up and heading off to my destination. I eventually put the car in to get fixed with a new hose.:)
I thought by replacing the hose it would rectify the heating problems, but it just got worse with the car overheating now too.:confused: Any Ideas??:eek:
I would be very grateful if someone out there could try and explain to me what they think it may be, as i dont want to get ripped off with the specialist and be out a fortune, as i already had a 147 and it cost me an arm and a leg, in the end, the car just wasn't to be!!:eek::cry::cry:
So please your help would be appreciated as i love my 156 :p:rolleyes:and this is the first problem i have had with it since i bought it 2 years ago (used). and do not want to part with it
Yours Hopefully:rolleyes:

First things first. Is it using water? If not it sounds as if it could be airlocked OR due to the extreme low temps we have just now it could be FROZEN. Is there anti freeze in the coolant system? Feel the radiator hoses and taste the coolant from the expansion tank, stick your finger in and taste it, if antifreeze is there you should taste a sweet then bitter from it. My guess is it's frozen as not enough antifreeze in it.

I'd agree that - if its only done this recently - its likely to be down to the coolant being frozen. Start your car and let it idle, checking the temperature gauge - if when it gets higher than 90 the top hose from the thermostat (on the gearbox end of the engine) to the radiator doesn't get hot - and feels stiff, then its almost certain that the radiator is frozen. Don't use the car like this, or you could do serious damage.

You could try thawing the hose by pouring hot water over it, but this won't really clear the frozen water from the radiator. If you can get the car into a friends garage where the whole engine bay can warm up to thaw the radiator, then remove one of the main hoses - either the one mentioned above, or preferably the lower hose to the radiator, and drain off several pints of water, then refill with concentrate antifreeze......(after reconnecting the hose, of course - have to say that - you wouldn't be the first to pour frsh coolant in the top and wonder why your feet were getting wet:lol:)

Take a look here, I had the same problem:

http://www.alfaowner.com/Forum/alfa-147-156-and-gt/202198-help-156-overheating-dispite-being-10-outside.html

We figured my radiator (and prob heater matrix) was frozen and this stopped coolant from circulating. I ran my car at idle and the temp went up to about 120*C but not much higher than that, don't drive it as it will rocket up. This seemed to thaw mine out and the temp settled. If it does start overheating then shut it down and do what has been suggested and thaw out the engine bay. Maybe use a fan heater to speed things up?

I also bled some water out of the radiator on the left hand side, I then poured 1L of concentrate antifreeze back into header tank. Should stop it freezing again.

Have been driving all day today and it seems ok.

Good luck,
Iain

DO NOT START A FROZEN ENGINE as you can shear off the water pump impellor or even snap the timing belt with of course the obvious conceqences. you need to defrost the engine first! once its defrosted run it. if it still overheats you may have sheared the w/pump impellor. if it doesnt refill with antifreeze. also dont just leave it ice expands and can crack radiators and engines wide open

Overheating and no hot air...All Fixed!

Hey Guys:D
Thanks a bunch for your response to my problem..looks like all your responses mounted up to the same thing...The big Freeze!:D:thumbs:

Take your point powercut - only suggested it as OP had already been running the engine....;)

Mazey - heater could still be frozen - or the heater valve could have been damaged by trying to open when frozen. Can you tell if the pipes going to the heater (two approx 1" diameter pipes running from near the thermostat back to the bulkhead) are getting warm?

yes i agree with what you are saying could still be frozen heater matrix of damaged valve. i think at this point i would now drive the car until its defo thawed out and maybe buy one of those in car plug in electric heaters as a temp measure and also to help thaw out the matrix
