Scan Gauge II Reviewed

Scan Gauge II Reviewed

Popular MVS Volvo Forums member Robert (rspi) tells us what he thinks of the Scan Gauge II.

My review of the Scan Gauge II that I purchased for iPd. ScanGauge II is worth the $$$.

I’m a little bit of a number geek and like to know what is going on with certain things all the time. So I decided to purchase one of the Scan Gauge II code scanner, etc., from iPd. Yes you can get them from other places, I just like to do business with companies that support us Volvo owners. So I purchased one in July 2009. My primary reason was to have a trip computer in my ’97 960.

I was so busy traveling, working, etc., that the thing sat in the box for about 6 weeks. Eeeekkkk! So much for the 30 day money back warranty. Anyway, I finally opened the box and hooked it up to my 960. My main goal was to check my fuel consumption. I’d like to know what kind of gas milage I’m getting, especially at $3.75 per gallon for 93 octane . Pluged it in and it fired right up. It took about 20 seconds to sync with my ECU but I was ready to start playing then. The 1st thing I did was check my CEL. Ah, P0330, misfire #3, it reset the code in seconds.

DIY: 1998 S70 GLT Turbo Coolant Hoses, 2 Radiator Hoses

DIY Turbo Coolant Hoses, 2 Radiator Hoses

MVS Volvo Forums member extraordinaire CN90 writes a beautiful DIY for how to replace a 1998′s coolant hoses and radiator hoses.

This is strictly preventive maintenance:

- The Turbo Coolant Hose was bulging and about explode any time.
- The Lower Rad Hose is leaking at the radiator side.
- Since I am replacing the Turbo Coolant Hose, I may as well replace both Rad Hoses.


- Lower Rad Hose PN 9470409 for Turbo (NA different PN); about $35 at dealer.
- Upper Rad Hose PN 1335433, about $15 at dealer.
- Turbo Coolant Inlet Hose PN 6842190, about $8 at dealer.

Modded 245 – What Went Wrong?


If I’m honest, if I had the last 13 years with the Volvo again, I would have stripped the shell a decade ago when it stopped being my daily, and fitted an LS V8, T56 gearbox and a BMW M3 back end. The interior would still only have two seats, but it would be more complete – a nicer place to be. But I didn’t, so that’s enough of that.

English Volvo 245 owner and Speed Hunter Bryn Musselwhite talks about the “organic” process of making his 240 wagon into a fast, fast Volvo.

How to Buy a Volvo

How to Buy a Volvo

Volvo owner, Volvo DIY’er, and MVS Volvo Forums Contributor mecheng gives us his outstanding essay on how to buy a Volvo.


I am writing this guide to help the general public and enthusiast when looking for a Volvo 850, S70, referred to as the P80 series from 1993-2000. It is also referred to the 854 or 855, where the last digit is the number of doors. Why, you ask well there are still quite a few on the road which is a testament to their overall durability and corrosion resistance.

Long before the typical reliable Japanese car will rust to its demise, the Volvo will still be running strong (ask me how I know). This guide is not all encompassing and the reader is encouraged to do all the standard basic checks when buying any old car. Like, did this car take a swim in a lake, is it composed of two different Volvos welded together after getting demolished at your local derby? Those are things you will have to investigate yourself with a Carfax report and trained eye or just have open and look for simple things: ie: welds on the frame = bad. I don’t intend to cover all the specs, variants for that you have many other sources.


“The one word everyone asks is: are they reliable? In a word, I would say YES but they need maintenance to get the most worry free miles.”


The one word everyone asks is: are they reliable? In a word, I would say YES but they need maintenance to get the most worry free miles. They are not the kind of car that is set and forget; they need small amounts of love, as I will get into. Overall, I have been pleasantly surprised with their reliability because they are sometimes lumped into the General: European cars are not reliable category which is false.

Do our cars get used to one brand of fuel?


MVS Forums Member huzzsaba:

Recently on a road trip, I filled up like I usually do at Canadian tire and got decent gas mileage that I usually get which is around 22 mpg. On the way back, I had to fill up at shell because there was no Canadian tire around, and I got the worst gas mileage in a long time which was around 18 mpg. It also felt like the car did not want to pick up speed.

Q: Do our cars get used to one brand of fuel?

A: No.

Volvoninja jimmy57 explains:

Every drop of fuel is a new world.

The engine control module (ECM) gets input from oxygen sensors and from the knock sensors that are info that has to do with fuel burn. If the fuel is higher in ethanol then the O2 sensor gives a leaner indication and the ECM adds fuel to get the input from O2 sensor within proper range. If the fuel is low octane (who polices octane of fuel against what is posted on pump?) then the ECM retards timing and then undoes the change to test for knock again. After a few knock “tests” that show high tendency for knock the ECM will adapt timing cylinder by cylinder until the level is found where knock is nil. This adaptive is load range dependent and is not long term. Periodically the ECM will tet for knock and will return to normal ignition mapping when knock is not longer present.
