Just a quick moan about last nights frustrations of not being able to undo a number of phillips head bolts.
I have now spent about 3 hours trying to remove the four bolts securing the heating matrix without any signs of movement other than cross-heading the screws.
I have tried some of the usual techniques, covering in oil and leaving for a couple of days, using a flat head screwdriver, hammering in a driver bit and mole grips but the metal is so weak nothing will bite.
I checked the welded in nuts from the floor heater vents and they are not rusty at all. Then in trying to get a better angle to one of the screws I decided it might be easier if I removed the starter solenoid switch, but then I ran into another phillips head bolt that stopped me in my tracks again!!
I think the only solution is to drill them out with a left hand drill bit which I don't own, yet! I will certainly replace them with nice socket bolt heads.
LOL...I did the same thing. I had to use plan B . Drill the screws attaching the heating box. Socket bolt heads will replace every Philips headed bolt in the car.
