What does the sertting with the number one and number two do? is one a faster fan... please help

Install a fully charged battery. Put on the parking brake and see if the key can be removed. If you need further help, please specify year and exact model. A VIN number would be helpful.

Actually, rather than replace the head, you can fix the spark plug hole with a "Time-Sert":

One thing they talk about on the site, "Ford spark plug blow-out? Repair kit part number 5553 Ford Triton spark plug kit will repair blown out spark plug's in Ford heads."
Here's the page for Ford's repair kits:

I've used these for years, and they work great!
Much better than a Helicoil, as the Time-Sert retains full thread strength!

But....I would STILL recommend removing the head to do this repair, so as to avoid metal chips/shavings from falling into the cylinder, but you'll save the cost of a new head!

Yes, yes, and yes.

A Time-sert is the best, as they actually have kits specially for drain plugs.

They're better than heli-coils, because they give full thread strength.
Also, a heli-coil's alright for something like a stud that you'll put in once, then leave alone.
But it it's something that you'll remove and reinstall time after time (like a spark plug, or a drain plug), eventually the heli-coil starts to UNcoil on you.

When you install the Time-Sert, the end threads (the first to go into the threaded hole) are expanded outward into the threads it screws into, locking it into place, but still allows removal with a EZ-Out if down the road you damage it.
For a drain plug I'd put a dab of thread dope (the paste, rather than the tape) on the threads just for a little added insurance against leakage.
Time-Serts come in different lengths, so you can measure and get one that is shorter than the material thickness you are installing it in so it doesn't protrude, which allows for full drainage of the oil.

Try to remove the dust buildup in the back of the tower. If necessary unscrew it and vacuum clean.

What is the model number to your Sylvania TV?

yes it will be fine.

You need to get a 'Helicoil' or 'Time-sert' kit for that particular thread (diameter & pitch)
They come with a larger drill & tap + inserts
'Time-serts' by Wurth UK are the best but expensive for 1 thread (I know I have most popular sizes)

Hope this helps (if so please mark as very helpful)

yes time -serts can be useed to be torque

A fan that no longer works will cause a heat problem. While it may not cause a complete failure, it can cause some strange things to start happening. Your best best is to shut the PC down and remove the cover. Restart the PC an determine which fan(s) has stopped working.

At this point, you can either 1) contact IBM for a replacement fan or 2) remove the fan yourself and google the name and model number of the fan to find a direct replacement and either order online or 3) visit a local PC repair shop to buy a replacement fan that matches the defective one.

Buying direct from IBM will probably cost the most, but will be the exact type needed for your PC. Buying locally will probably be cheaper and faster, but may not be an exact replacement unless it is the same model, etc.

When calling IBM you'll need the computer model, serial number and any other identifying numbers on it for them to help you out.

Fan motor needs replaced.
