Not good my friend most or all of the coolant should be gone by now. sounds like you might have a hairline crack alowing antifreeze to newly enter your crankcase. Antifreeze in an engine for more than 100 miles turns into a creamy foam that exits your drain plug. and if the engine overheated and stalled out definitly. sorry Man.

Can i put coolent leak repair through the reservoir tank as we cant find the radiator cap in this VW Bora v5


It depends on the type of leak sealer and how much flow there is through the degassing tank. If the leak sealer is a solid it should not be put in the tank and if it is a liquid with lots of solids that must be vigorously shaken it would be better if it isn't added to the tank unless the coolant level is first lowered to effectively empty the tank so the leak sealer will enter the main cooling system almost immediately.

In almost every case the best results are usually obtained by adding directly to the radiator and in the absence of a radiator cap or a filler on the engine, disconnecting the top radiator hose and adding the leak sealer there before reconnecting and topping up with the saved coolant will ensure maximum efficiency of the product.

Ensure that the battery is fully charged. Refer to Battery Inspection/Test .


?€¢
Ensure that the battery cables are clean and tight.

?€¢
Ensure that the grounds are clean, tight, and in the correct location.


Refer to Ground Distribution Schematics and Power and Grounding Component Views .


?€¢
Inspect for aftermarket devices that could affect the operation of the system. Refer to Checking Aftermarket Accessories .


?€¢
Search for applicable service bulletins.

To ensure that retained accessory power (RAP) mode is inactive, if equipped, open the drivers door during the following step.

The engine may start during the following step. Turn OFF the engine as soon as you have observed the crank power mode.

  1. Access the Power Mode parameter on the scan tool.
  2. Rotate the ignition switch, operate the ignition mode switch, through all positions while observing the Power Mode parameter. Refer to Body Control System Description and Operation for a list of the power mode states that correspond with each switch position.

Sometime when i g start my 1987 corvette its acts like its dead, i turn on the key all the lightcome icluding the secuity light but it will not turn over, iof i wait for like 10 minutes go back out an


no crank, it called.
what lights come on, there are like 30 lights or more.
HL, parking, dash , warning, dome, tail, stop. blinkers and dimmer dash lights. to name but a few.
sounds to me like , custom alarm, and is acting up.
but id need to sit in the cockpit to see whats' really going on.

all gas engines eveny back in mid 80s, or model A ford
the starter can be hot wired or jumper cable cranked.
see that tiny lug on the solenoid ,
so if jumper cables fail. (off running car) sill dead?
then you next hot wire the starter solenoid tiny lug
fails to crank, ? then hit the side of starter with a hammer
crank now>?

ok , hot wiring the solenoid (key is pocket)
the starter turns the crankshaft over fast,
the starter and battery are working now. so what is wrong
this is called the KEY line.
the KEY line is dead.
my wild guess, is aftermarket alarm installed and its breaking the key
line, like many do.

What causes an engine to overheat?


Are these boxer type engines like subaru? If so you need to "burp" the radiator to remove air pocket in the engine as the radiator coolant flows into the engine from the bottm,. what I call a bottom feeder. To do this look around the side of the radiator there should be some kind of bleeder valve there
PS> you really should include the YEAR, Make and Model along with engine size - with some more details to get better results here - like had you flushed the radiator or removed or replaced any coolant,. some history of how it got into this position...
Best regards

Alternator


Instructions1 Clean the positive and negative battery terminals to ensure a good connection with the tester's clamps.
2 Connect the positive and negative clamps to the appropriate battery terminals. The clamps must make firm contact with the battery terminals or the test results will be inaccurate or the tester may not work at all.
3 Turn the tester on and choose the option for "full charging system test." This will test your battery, starter and alternator and provide the most accurate picture of the problem.
4 Follow the directions on the tester's screen. These instructions will include cranking the vehicle after the battery test is performed, holding the engine at a certain RPM range and turning on certain accessories.
5 Read the results displayed on the tester's screen. The tester should scroll through the results, starting with the battery, then the starter and finally the alternator. An alternator test result showing diode ripple problems indicates a bad alternator.

Oil change tech says my idle relearn needs fixing on my 2001 Yukon XL...can my husband do this?


{: ) Anytime the powertrain control module (PCM) or the battery is disconnected, the PCM loses power, or the PCM is reprogrammed, the PCMs learned idle position is lost. The engine idle is unstable when the learned idle position is lost. For a 2001 Yukon XL, you can try these steps: Automatic Transmission
  1. Turn OFF the ignition.
  2. Restore the PCM battery feed. ( IF it was disconnected)
  3. Turn OFF the A/C controls.
  4. Set the parking brake and block the drive wheels.
  5. Start the engine.
  6. Ensure that the engine coolant temperature is more than 80°C (176°F).
  7. Shift the transmission into Drive.
  8. Allow the engine to idle for 5 minutes.
  9. Shift the transmission into Park.
  10. Allow the engine to idle for 5 minutes.
  11. Turn OFF the engine for 30 seconds.
Manual Transmission
  1. Turn OFF the ignition.
  2. Restore the PCM battery feed. (IF it was disconnected)
  3. Turn OFF the A/C controls.
  4. Set the parking brake and block the drive wheels.
  5. Place the transmission in Neutral.
  6. Start the engine.
  7. Ensure that the engine coolant temperature is more than 80°C (176°F).
  8. Allow the engine to idle for 5 minutes.
  9. Turn OFF the engine for 30 seconds.
After the procedure, you can do testing and observations. If unsuccessful, you may repeat the steps.
Also, the best time to relearn idle is after a throttle body clean (from carbon deposits)

Generally, you can check and test alternator with this procedure...

1. Clean the positive and negative battery terminals to ensure a good connection with the tester's clamps.
2. Connect the positive and negative clamps to the appropriate battery terminals. The clamps must make firm contact with the battery terminals or the test results will be inaccurate or the tester may not work at all.
3. Turn the tester on and choose the option for "full charging system test." This will test your battery, starter and alternator and provide the most accurate picture of the problem.
4. Follow the directions on the tester's screen. These instructions will include cranking the vehicle after the battery test is performed, holding the engine at a certain RPM range and turning on certain accessories.
5. Read the results displayed on the tester's screen. The tester should scroll through the results, starting with the battery, then the starter and finally the alternator. An alternator test result showing diode ripple problems indicates a bad alternator.

Hope helps (remember rated this).
