What is an 02 sensor upstream 98 astro van


02 sensor is your oxygen sensor, 98 chevy astro carries 3 oxygen sensor. i belived your bad sensor is on the passenger side by the exhaust manifold but if not try the drivers side all the oxygen sensor for this van are the same. you need to go under the van to replace it, if is to hard to get it out turn your van for five minutes then turn it off and try again, be carefull not to burn your self. the one close to the catalytic converter is the downstream oxygen sensor ok, good luck!!!!!!

I have a '98 Astro van that starts fine when cold but is hard to start win hot. It idle and runs fine. After it cools down completely, it will start OK. I was told it could be a fuel pressure problem and...


I agree, replace the Coolant temp sensor, it will have 2 wires going to it, Not 1. Usually located just behind the breather near the thermostat outlet.

This sensor controlles your timing and fuel to air ratio.

Coolant temperature relay switch


Most vehicles use a coolant temperature sensor which is located near the thermostat directly connected into the coolant line, or near the thermostat housing, there are relays for the cooling fan which is usually located in the power distribution box under the hood.
