#39 of 57 Re: 89 Mazda B-2200 Running Roughly [the_bean] by 7801brian Dec 31, 2008 (6:46 pm)
Replying to: the_bean (Feb 29, 2008 10:47 am) I was just wondering if you still had your B-2000 engine for sale. If you do, I was wondering how much you wanted for it and what part of the U.S. you live in.   Thanks! 7801brian
#40 of 57 B2300 Engine coolant system eating itself by a70roadster Jan 06, 2009 (4:40 pm)
I have a 2002 B2300 P/U. Went to change the thermostat and found the engine cooling system eroding internally. Seems like the wrong coolant was put in the engine. Funny thing, the coolant has not been replaced. It was topped off twice. 1 by the dealer and 1 by the oil change place. 78k Miles and no one ever recommended the coolant be replaced during all of the service visits. Because the warranty expired, MAZDA disavowed any responsibility but offered a couple hundred dollars in service credits. BEWARE the coolant you use. DO NOT USE MAZDA EXTENDED LIFE COOLANT. See owners manual page 275. I believe this is what was in my engine because when it was drained, it was orange/brown in color NOT GREEN. WORD to the wise.

I have an engine miss under load or heavy acceleration. It seems to be much worse in cold weather. I have changed the plugs and plug wires with no help. I have the ECM code checked, it indicated a temperature modual fault. I changed the electronic thermostat, but no help, trucks runs in normal temperature range. I have visually inspected the coil and see no issues like cracks or moisture. The truck has 118K miles and has been well maintained. Any one have a similar problem?

Replying to: TimSC (Jan 24, 2009 9:03 am) yeah actually i do! but not with my b2000. its actually with my F2T mx-6. my mazda cuts out at 4psi and between 3 and 4 thousand RPM. i've had it checked and was told it was the ignitor. i replaced the whole distributor. this helped a bit but the problem still remains. after calling around and talking to a few car gods i have 3 possible answers (all sensors) 1) the cam/speed sensor 2) the temp sensor or 3) the TPS (throttle position sensor) i was told the problem is definately electrical! i'm yet to atttemp the replace these sensors but if/when you fix your truck please let me know and i'll do the same for you when i fix my engine issues.

#44 of 57 87 b2000 engine vibration by 19k40rocky Mar 07, 2009 (9:27 am)
I got a used engine out of a salvage yard in Colorado recently to replace my other engine that suddenly had a knock and bad compression on one cylinder and turned the antifreeze black and oily. Anyway, the new engine has a mild vibration to it starting around 2000rpm and keeps it up through the RPM range. Pickup really doesn't want to go past 70 mph and makes the steering wheel feel like you are hanging onto a vibrator. It has 140 compression on all the cylinders. Vacuum gauge holds 20 inches steady. The pan looks like it has been taken off before as it has orange form a gasket on it. I am wondering if someone had this thing apart and turned a rod around backwards or something. If it is could I unbolt the rod and turn it without messing up the rings? Not really excited about having to pull this engine back out. I had called the salvage yard I got if from and they told me to change out the harmonic balencer. That didn't work either and don't think they are going to stand behind this engine. Any ideas for a out there?
#45 of 57 timing marks by lion_of_judah Apr 18, 2009 (12:47 pm)
where is the timing mark for crankshaft (?) I see the diamond (oil pump) and triangle (camshaft) how do i find tdc to set the timing? mazda b 2500 truck Replies to this message: the_bean (Apr 21, 2009 9:08 am)

Replying to: lion_of_judah (Apr 18, 2009 12:47 pm) there will be a small notch on the pulley. it may have lost its color. the best way to find it is to put the car in gear (engine off) unplug the coil and roll the car forward until you see it. then mark it with a bright colored paint pen. when the notch aligns with the "TDC" mark your golden. OR you can remove the #1 spark plug, place your finger over the whole and turn the crankshaft. when its on the compression cycle you'll feel air being forced past your finger once the air stops blowing or you start to feel suction your very close to TDC

I Have a 1986 mazda b2000. Timing problem? Will not start. The belts and fan turns. Sounds like you are trying to start a electric motor. There are no signs of life. The guy i got it from told me he got in it one day and it was running sluggish and the next day he got to the end of his street and it died and that was that.   I Tried starting fluid and that will not work at all.   Got it for $300.00 nice truck if i can get it running.

Replying to: lonestar1045 (Apr 24, 2009 12:29 am) Have you got spark? Pull a plug wire to see if you got a good spark. If not it may be as simple as a distributor cap gone bad. There is a little carbon piece in under the cap that can go bad and do that as happened to me once. Also might be the electronic control module in the distributor. they go bad too.
