Re: Low compression on cylinders 2,4,6 after belt tensioner broke

I had a timing belt tensioner fail and the #1 cam was off by 1 tooth and all others were dead on. With this slight misalignment the engine barely ran. I managed to dump it off the car where I could...

Re: 2002 L300 A/C problem

Have you tested the clutch relay?

Manually activate the clutch and verify it remains engaged?

It sounds more like a failing clutch or relay or both.

Re: Passenger size floor matt is full of Dex Cool

I'll flush the heater core when I replace the O-rings. However, when it comes to heat, the Saturn heats better and faster than our other two vehicles (Dodge Ram 2500, and an 2000 Yaris Hach Back). ...

Re: Passenger size floor matt is full of Dex Cool

I placed two paper towels beneath the heater core another under the pipe connections. I left them there for 3 days. I found drips beneath the pipe connections and none under the heater core. I...

Passenger size floor matt is full of Dex Cool

I have had this issue once before and it vanished for a long time. Over the winter, somehow, the Saturn was leaking coolant and the light came on to add coolant. I added 2 inches of Dex Cool to...

Re: 2002 lw300 3.0l v6 timing belt broke, bent valves/rods

I would not use radiator hose, it is not made for fuel contact. A pickup truck filler hose is perfect for the larger intake hoses. You'll have to buy it by the foot from an automatic store, but you...

Re: 2001 L200 vibration while accelerating

Rotate your tires and see if the vibration problem changes.

Re: 02 LW300 V6 Fuel Pump and OBD2 Trouble

So the relay was dropping voltage across it causing the connected devices to experience low voltage hence their unpredictable behavior. Nice find!

Re: 02 LW300 V6 Fuel Pump and OBD2 Trouble

The intermittentness of the gauges and OBD2 interconnect still makes me believe the key switch could be at fault. Why would it work once and another time not? Digital elections don't act like that,...

Re: 02 LW300 V6 Fuel Pump and OBD2 Trouble

A completely broken timing belt would allow the valves to seat and as long as the cam shafts are not spinning, the engine would simply rotate and not start. Some valves could hit the piston(s). It...

Re: 02 LW300 V6 Fuel Pump and OBD2 Trouble

A defective CPS can't disable to the starter from spinning the engine. The CPS strictly is a signal generator to provide clocking signals used to time the engine. It's the chicken and the egg...

Re: 02 LW300 V6 Fuel Pump and OBD2 Trouble

The engine will rotate but will not start if the crank position sensor is bad. I am thinking the key switch is not really switching the RUN wire to ON, therefore gauges don't work and the ODBII...

Re: 02 LW300 V6 Fuel Pump and OBD2 Trouble

Don't rely on a ohm's test to determine crank position sensor is good or not. A bad one will simply not provide clocking to the ECM and therefore no start. The crank position sensor provides the...

Re: 02 LW300 V6 Fuel Pump and OBD2 Trouble

Have you considered the fuel filter is plugged? Disconnecting the fuel filter and testing for fuel pump is working might be good to isolated the a fuel delivery issue.

Re: New Thermostat Replacement, Still Only Running At 180 Degrees. Why ?!

The entire behavior of the coolant system depends on the input from the temperature sensor. It could be indicating the engine is hot and it is not. Have you ever seen a PO128 code?

Re: New Thermostat Replacement, Still Only Running At 180 Degrees. Why ?!

For sheets and giggles, I would change the temperature sensor and see what happens. Also, make certain there is no air trapped in the coolant system.

Re: New Thermostat Replacement, Still Only Running At 180 Degrees. Why ?!

Are you certain they actually replaced the thermostat? If the same codes returned, they did something wrong.

Did you burp the system as described by others? If you have air trapped in the...

Re: New Thermostat Replacement, Still Only Running At 180 Degrees. Why ?!

How are you measuring you're temperature?

What problem are you experiencing with the temp too low?

Re: Noise Coming From Timing Belt Cover, Rear Sprocket

Better to diagnose what is and forget about what is not otherwise you consider iterations which mean nothing and convolute the works.

Re: Noise Coming From Timing Belt Cover, Rear Sprocket

It may run for another 5,000 miles or quit in less than 10 miles. When our timing belt tensioner failed, we had just driven 200 miles, I noticed a lack of power going down the highway. It was...
