I unfortunately threw my back out a few days ago so no new progress on the MG, but I did replace the thermostat in my Volvo over Easter so I figured I’d throw this video up now. I was getting a check engine light and when I pulled the codes it gave me P0128 code. After doing some searching on the interwebs that translates to “Coolant Temp Below Thermostat Regulating Temp”. From the looks of it most people replaced their coolant temp sensor first which did not fix the problem, then they went for the thermostat which did fix the problem. I figured I’d cut to the chase and just go right for the thermostat and sure enough that fixed the problem and only cost me $10.

It’s been a while since I worked on the MG B so I thought I’d do a little recap and bring everyone back up to speed.

Since I was getting a whole lot of use from the stereo I put in the MG I decided to throw it into my wife’s 1998 Jeep Grand Cherokee. In video I give step by step instructions on how it was done.

In this episode I replace an auction sensor on my 2001 Volvo S40. I discovered the problem when I started getting a check engine light, I pulled the codes with an OBD-II reader and the code it found was P0130 after some googling that pointed me in the direction of the oxygen sensor.

My volvo S40 has what’s called an intereference design engine, basicly what this means is that if the timing belt were to break the valve would stop moving and would hang in a position that would ‘interfere’ with the pistons path of travel. It wouldn’t really be an ‘oops pardon me while I squeeze by’ type of interference it would be possible broken piston heads and bent and broken valves.

Thus it’s recommend that the timing belt is replaced ever 100k miles, well right now I’m over 120k and I’m nervouse to say the least.

My dad was kind enough to help me out(did most of the work) and we got it done.
