Re: Help with ECM fault code P048000, fan 1 control circuit

To get help with a DTC, give us the exact wording the Autel gives for a P048000. When a thermostat breaks up internally allowing coolant to flow unrestricted, there is no overheating condition. You'll instead have startup underheating -- it will take longer for the engine to come up to temperature.

Re: evap purge canister

There are dozens of possible leak points in the fuel / EVAP system. It's not recommended to guess your way through this maze. The diagnostic approach to use is the pressurized smoke test. Many repair shops have the equipment. You should make clear you want to pin-point the leak making repair actiona...

Re: Strange noise on startup in cold weather

I have serious concerns about the substitution of plastic parts for metal on engines. Add -30F to that equation, and I would cringe just pressing the "START" button.

Re: Strange noise on startup in cold weather

1. Does this sound mechanical to you? YES, YOU CAN HEAR THE FREQUENCY COME DOWN WITH THE RPMS. LET'S TRY SOME FREQUENCY ANALYSIS. ON THE KEYBOARD, THE NOTE WE'RE HEARING IS A "G" ABOVE 440-A, or 785 Hz. That frequency is NOT related to any multiple of the crankshaft 26.6 Hz, or firing rate 160 Hz. 2...

Re: Instrument panel: avg mpg/mph -- trip 1/2 & overall?

There's a section called Trip Statistics in the menus under "MyCar".

As far as undefined results on the dash display, take something like instantaneous "miles per gallon". When the car is not moving, the value is considered undefined, which displays as "--".

Re: Oil Anti Drain Valve for the P3 -- 3.0T and 3.2 Topic is solved

Paul - I have the Volvo B6304 T6 (Volvo-Ford) engine. I'm hearing engine friction noise for about 3 seconds at cold start-up, but no similar noise if I shut down and restart. I'm suspecting the oil filter anti-drain-back valve is leaky/broken. Is there a way to test the filter housing, cap removed, ...

Re: [2001 V70 2.4T] Occasional coolant reservoir boilover

It's possible your radiator is not shedding heat efficiently. It's usually clogged internal coolant flow, or poor airflow. Have you checked the front surface of the radiator for flattened fins? I've seen some cratered over 50% of surface area. Your running temp. is too high. Normal is 85-90C. When y...

Re: Service and Workshop Manual

It would help to state if you have an AWD or FWD. The FWD fuel tank is much simpler to replace. The AWD requires removing all of the interfering drive train components.
