Yes it is part of the cooling system. It is not designed to allow for the hot air in the engine compartment to circulate, rather its supposed to aid in pushing the hot air downward and out of the engine bay. Band aid for a less than adequate cooling system.
@@freedom1garageyes it's a stop gap measure. I just replaced glow plug #4 behind the steering shaft and wasn't able to separate it so I used a wobble extension and shallow six point socket. For some reason the connector nut was 7mm instead of 8mm but so was the nut I had in my collection. The thread is a standard M4. I couldn't reuse the old nut because the connection stem just snapped off when I went to loosen it. This was probably the first one to fail with the rest of them not far behind but it's good to know at least this one came out quite easily. Other videos show some nightmare scenarios where the hex snaps off the glow plug leaving you with nothing to spin the plug out with. Then there are basically three methods for removal at that point, easy out if the electrode broke off and came out. Weld a nut onto what's left of the glow plug and try to spin it our and worst case drill out the threads and tap the tube to extract what's left. I soaked mine if penetrating oil before I tried removing it with the engine cold and it broke free easily and came right out. There doesn't really seem to be consensus on which is better hot or cold engine but cold worked for me in this one instance. Steel into aluminum has always been tricky.
The stepper motors are Notorious for going bad in those pick ups on the gauge cluster!
Good video to help fix glow plugs for sure. You do a good job and need more subscribers. Thx
Thanks farmark! Our numbers are growing and we consistently have good watch hours. So our content must be helpful to some. More to come!!
That silly thing is a fan shroud that causes the air to circulate in the engine compartment. It was added to reduce cooling issues on earlier models.
