Hi,
I've finally got my Mega back on the road but am still having a problem with my heater :(.
I got it up to running temp. and noticed that on tick over the temp. dial crept up to 100 and when i put the heater full on it remained cold, on checking the 2 pipes coming through the bulkhead to the matrix the bottom pipe was red hot and the top was cold :o.
The heater and running temp. was fine before i did the cambelt, water pump and breather clean and so am worried that i have possibly put a pipe on wrong :question.
The HBV seems OK(no leaks and not touched in work carried out).
Any ideas as this is getting me down now after all the trouble i(and RichieRich)went to refitting the metal bar behind the radio which operates the heater flaps and still ending up with a non working heater :(.
Thanks,
Pete :).

My initial though is the heater matrix is blocked. Might be worth disconnecting pipes going through baukhead, and running a hose through the matrix
-
Thanks, I'll give that a go and keep me finger's crossed :-X.
I take it a blocked matrix would cause the engine temp. to climb a bit higher than normal as the top and bottom radiator hoses were so hot i couldn't touch them for more than a few seconds :o.

Well today(Saturday)i took the Mega out for about a 6 mile run and when i got back i checked the matrix pipes again and this time they were both red hot so tried the heater and it seemed to work fine :-X.
The blockage as TheBoy suggested seems to have cleared itself :) but the engine still seems to run hot especially when stopped in traffic or at lights, so my ? is what should the temp. gauge read when sitting for a while and the fan comes on and how many fans should actually come on?
I know these big engines get hot and as i said you can't really touch the radiator hoses for for more than a second, so is this normal as i don't want to boil the engine or do any damage such as HG :o. Is there any way of testing if it's just normal heat as it doesn't blow any water out of the overflow or anything like that :-/.
Any help to put my mind at rest greatly appreciated,
Cheers,
Pete :y.

Temperature gauge should sit halfway which is 95 degrees (unless a facelift) then in traffic should go up to around 97 then the fans should kick in bringing the temp back down to 95. :y

Alright Daz, thanks for the reply.
Mine seems to sit near the 100 mark with fan/s on, do you know how many fans run when it/they start up?

Would have thought if the car was that hot Pete they would all kick on..
Have you checked the fuses under the bonnet in the triangular fusebox? Two 30 amp fuses iirc maybe Green..

No Daz but will tomorrow ;) is there 3 fans on a V6, 1 engine side and 2 the other side?

Yeap :y two front ones are the air con fans but do come on to help out.

Thanks for that Daz :y
It might be that not really having compared it to another car that it may be normal for mine as i had a Scorpio 2.9 a while back and when you opened the bonnet on that it was like opening an oven door :o.

Should not really be at the 100 mark though Pete :-[

Maybe my gauge is a bit over active :).
I have got another set of dials i could put in and see what it reads on that one :).
-
Look at the live data, and see if that co-relates with the gauge... the gauges aren't the best in the world
Failing that - make sure you give that matrix a damn good flush - it was clearly blocked by the symptoms, I had the exact thing on Max's car - I just wonder if the blockage has moved....
-
Are both pipe hot each side of the radiator? is the radiator itself hot all across it? I must admit I thought it could have been the rad but I could be wrong :-/

Excuse my ignorance, but what do you mean by what I've highlighted and it was possibly partially blocked due to not being started for 3 1/2 months but will try giving it a good flushing to be on the safe side :y

Think James means plugging a Tech 2 or "My Naff Code Reader" into the car to see what the actual car temperature is and not what the gauge is showing, but if the gauge was right before surely it just wont have gone out of sync?
My money still on the rad or fan fuses :y

Ah right Daz, gotcha :y.
As for the gauge i did have them out when i tried fitting some stick on white dials which meant removing the pins and the pointers :-[ so that may have something to do with it :-/.

If at the end of the day all else fails then I'll get it tested as James suggests to be safe :).
