2003 156 2.0 JTS - help needed
Guys - can anyone help with diagnosing these snags with my 156 please? Need to picture paint a bit for this - so please bear with me.
It's an 03 2.0 JTS with 116,000 miles on it. It's had most of the last year off whilst I got on with other stuff. I have fitted a new radiator as the car was running hot - the old rad was shot beyond believe - hanging would be a good description.
Since the new radiator went in - the engine then ran cold, barely moving off the C on the guage. So I've fitted a new thermostat housing - which has worked as the engine will come up to temperature.
The car has no MOT at the moment, so I can't legally drive it - but running the engine on the drive, after about 25 - 30 minutes the temp needle rises to the 3/4 mark on the guage - electric fan doesn't cut in - so I switch off at this point rather than risk it boiling up.
I've hooked up the fan to a live supply and it works....so presumably the switch controlling the fan is duff? Is that the one located on the fan shroud? Or - could it be something else?
Also - at idle speed the engine 'hunts' - especially before it warms up. The exhaust note at idle speed is uneven, like there's a misfire, it improves a bit when the engine is hot - but still doesn't seem right. Open the throttle and the lump smooths out nicely and revs like a turbine.
I've had the plugs out of it and checked them - all appear fine. Whilst in there I renewed all the spark plug tube oil seals, plus 1 x HT lead (old one came apart in my hand) as they had been immersed in an oil bath.
I put the car in for MOT and it failed - on a brake pipe (no worries there) - but the emissions were off the scale....?
So - can any of you learned guys on here shed some light on these snags please?
Any intel/suggestions/ideas gratefully received - thank you.
