Firstly, a thermostat that opens quicker will not give you better heat. Your heater core may be partially plugged causing a low flow issue. Another area to check would be the water pump impeller for corrosion or slipping on the shaft. Does the vehicle's cooling system operate well otherwise?

I think its a rubber o ring on the end of the sensor.

The manual says there is no dipstick. The transmission is a sealed unit, filled for life. It's really a bad design to not have a dipstick, because transmissions will weep a little fluid at times and it's a good idea to check the level once in a while. The Manual says that if it leaks fluid you have to repair or replace the transmission. Not a valid repair when the car has 160,000 miles and it's a pint low. There's a plug on the passenger side at the bottom of the transmission to check the level (with the engine running, so it needs to be on a lift) and there's a yellow filler plug hidden under the air cleaner on top of the transmission.If you put in 5 quarts, it is either too much or too little. Both cases will cause the fluid to foam, causing jerky shifting. Mine was too low at 185,000 miles and it was banging shifts when hot. By the way, that transmission needs about 9.8 quarts after a pan drop and filter change, so your 5 quarts is way too little.

replace radiator cap

ignition module is dead easy to replace right on top under the aluminum coil cover

try and dertermine as to where it is coming from by using a rag and drying the area - hopefully you can find it after doing so and then make the repair

The gm line of that erra runs their turn signal through the hazzard switch, when your turn signals are inop, try depressing the hazzard switch a few cycles, if this alows your turn signal to function again as hazard switch will be required to repair the problem, hope this helps

Sound like your master cylinder needs replacing.

sound to me like a wheel bearing in front or rear.

Maybe the timing belt hope it help

Check transmission fault code.Because some code when they appear put o?l pressure high to not burn the clutch and cause hard shift hope it help

Robin, if you smell gas you need to have that checked now!!! A fuel leak can result in a fire. Also check for engine codes and vacuum leaks The idle air control valve may be causing problems Hope this helps ,Bill

You did not give enough information about what you did not pass on emissions. Usually it is the co2. If that is the case, it is either the sensors at the catalytic convertor need replacing, or the catalytic converter itself. You can get sensors at the wrecking yard but NOT catalytic converters.

First ,check all vacume lines for leaks. Check all engine grounds for corrosion or EGR stuck open
