SOURCE: Mazda MPV Coolant Loss (but no overheat)
i had the same thing on my wifes 2000 mpv van...the ends of the radiator are made of some sort of composite type material....it had a slight crack in it....wasn't obvious until it got worse and started streaming water from it when warmed up....even after it cooled enough not to be spewing it was hard to actually see the crack though a few inches long....was hard to even see where the water and antifreeze mixture was coming from until i took out the radiator
SOURCE: 2001 Mazda MPV upper front oxygen sensor change
I replaced this sensor about 6 months ago. (If this is the sensor that is located near the firewall on the exhaust manifold under the ignition coil.) The only way to easily replace it, is to remove the MAF and air filter assy. then remove the intake plenum, remove the ignition coil, and then you'll have access to the sensor. You'll need a sensor removal socket. If the socket slips around the hex of the sensor, then you'll need to use a regular deepwell socket and cut the cable from the top of the sensor, or use a combination wrench that will fit it.
The most difficult part of removing the intake plenum is getting the nut loose from the EGR valve. DO NOT just remove the two bolts holding it to the intake plenum. It will not line up correctly during re-assembly and may not seal tightly either.
This took about a Saturday to do. You'll need new plenum gaskets to replace the old. While your at it remove the throttle body and clean the carbon from the ports that lead to the EGR valve and replace that gasket as well. The gaskets will run about $30.
