Here's the guide to the timing chain.The Ignition TimingComputer operated - electronically controlled (refer to decal)

One of two ways to fix this is to change the caliper bracket. This is the best way and probably the cheapest way as you can find plenty of these cars in wrecking yards.

The other way requires inserting a Heli Coil. You buy the Heli Coil kit for the original bolt and drill and tap the hole to a larger size and install the Heli Coil insert to restore the hole to original size.

Check the battery's state of charge-might be too low. Check battery post connections. Clean and retighten them, and check battery ground, and connection of cable to starter. Sounds like starter is not getting full battery voltage to work.

Lot's of these problems going around. First thing is to locate where the coolant is going. Is it leaking onto the ground or going through the engine and out the exhaust? As for no heat, Check to be sure you have enough antifreeze. Pure water can cause the engine to not warm up and result in no heat. Air in the system can also cause these problems and must be bled out through the air bleed screw on top of the engine. On most of these cars it is towards the passenger side front on a metal pipe. It's a funny looking fitting with a flat head screw on top and a hole on the side. With the system full and the car running, slowly open the screw until bubbles come out and continue to bleed until you get no more air out. Let the car run to reach normal running temp and try bleeding again and again until you can't get any air out (they're funny that way). If you can not locate coolant leaking onto the ground it's due to a blown head gasket or a cracked head.

Here's a guide on how to replace.Here's what it looks like.

under the hood is a relay, check that too, there should be 2 of the same you can switch quick to test, also both plugs must be in ( under the dash next to the heater motor and on the motor on the same set of wires ) - I could jam/wiggle the wires into the motor "plug" towards the motor and mine would work - brushes where wore out so you may have simply replaced a worn out motor with another worn out one. can test that easy with a couple of wires and a battery... if you have to wiggle the receptacle get a new motor.

Check brake light switch (likely faulty). This issue may not be related to the engine issue.If not the brake switch then check wiring for possible short circuit.

check your fuse box. High beams (brights) usually have their own fuse. Otherwise it could be a problem with your switch (i assume its one of the arms behind your steering wheel) buyt i would pull the fuse first. Refer to the diagram for your specific car. fuses are cheap and you can tell theyre blown when you pull them out (a break in the fuse)

Often times the headlights, brights and turn signals are on different fuses. I used to have a 98 and I was surprised at how many things were connected to each other in the fuse box. If you can not find a fuse related to the brights, then get a fuse tester and walk through all the fuse. If not, it is not a total loss, any car audio place installs alarms can trouble shoot it, if they want the money, rewire or fix it. They are usually cheaper then an autoshop.
