Gas smell in cabin of a 2001 mpv

Replaced water pump in MPV , later wife smell "fumes" in cab, not so much on recirculate air, no gas to be found on, under, or around van. I have no sense of smell, but my eyes seem to be burning after a 25 km drive.Took a few refills to top up antifreeze overfull tank. Might still be going down but I just look at it after our cold spell, at add. Oil filler cap had the sludge in it and the PVC hose had some too. Van runs great, with normal exhaust gases coming out the tailpipe. My thoughts are a compression test ( for a possible blown head gasket), I hear the back plugs are hard to get at so I'm not looking forward to that procedure. One thought off the net was the fuel vapour canister filling w/gas due to the check value not being connected w/ the vacuum line connected to the top port. So I checked it and the vacuum was present at the top port of the check valve( top being the one on top when mounted, ie: next to the electric part of the valve). Any thoughts?

SOURCE: My Mazda MPV randomly begins to

the gas cap and check engine light thing are related in terms of the EVAP system, or the evaporative emisions system. This is NOT where your surge, or "chug" is coming from. The surge could be coming from a Exhaust Gas Recurculation valve that is starting to bind or "hang up" a bit. DO you notice this happens more at lights, or when coming to a stop? if so it could be an idle air control vavle.

SOURCE: I filled up my 2002 Mazda MPV yesterday at Walmart, Manning

Could be bad gas, water in the gas? Run the tank down to about 1/4 and put gas from somewhere else in it. Maybe higher octane for one tank full. Maybe put an additive in with it. If it clears up, then it was the gas.

SOURCE: 2002 Mazda MPV 6 cylinder Lx van. Check engine

You might access the Engine Control Module (ECM) using diagnostic equipment connected to the data link connector of the car, in order to pull out all Diagnostic Trouble Codes (DTC) memored. Also through "parameters measurements" menu check the upstream & downstream oxygen sensors voltage values - for bank1 & bank2 of V6 engine. For upstream oxygen sensors you should have a permanent fluctuation of voltage between 0,1 Volts and 0,9 Volts. For downstream oxygen sensors you should have a constant voltage value around 0,4 Volts. I suspect bad upstream oxygen sensor(s), but obligatory scan first the ECM memory and check oxygen sensors voltage!

SOURCE: my mazda mpv 2001 coolant leaking somewhere.

1. External Leaks
You need to get the vehicle to a mechanic to check all flexible coolant hoses, hose connections, around the exterior of the water pump and the entire radiator. To do properly the vehicle also needs to be on a hoist. If there is an external leak you should find coolant dripping from the front of the car while the engine is idling and the cooling system is fully pressurized. However it depends how bad the leak is and it's location.

2. Internal Leak

If coolant is leaking into the engine this is a serious problem and needs to be identified by a competent mechanic. For example, if you have a blown head gasket coolant will blow into the engine and contaminate the engine oil. If you check the oil in the engine's sump it should be completely free from coolant contamination.
You should also check the coolant in the radiator for any signs of oil contamination. If there is coolant in the oil then there will also likely be engine oil which has blown into the engines coolant passages and then mixed with the coolant.
IF you can find traces of coolant in your engine oil (or oil in the coolant) the likely problem will be a blown head gasket and the head on the engine will need to be removed and inspected .

Blown head gaskets are usually a result of an owner allowing the engine to overheat as a result of low coolant level, failed water pump or faulty thermostat. Overheating can also cause major damage to the head on the engine.

It's probably a fuel pump issue. Sounds like it's not giving the engine enough fuel.

MPV 2002. Black particles come out from air vents


I get the feeling this is the first time you've used the heater? Its probably accumulated dust. As long as you don't get a burning smell or smell exhaust fumes you should be ok after a few hours use.

Does 2004 Mazda MPV ES equip with a cabin air filter?


(cabin filter solution) Their is an cabin airfiliter behind the glove compartment (2004 mazda mpv) which is very easy to take off. Replace the airfilter or clean it with soap and water. Open the glove box and on the bottom left had side of the glove box if you apply enough presure on it by pulling it out towards you and slightly down it should pop off. The right side should slide out immediately following the left side pop. All it is, is a fork like claw holding on to a bar. On the ride side is a bar sliding into a hole. That should do the trick. After the first time its a sinch.

2004 Mazda MPV cabin air is just not getting hot enough.


If changing the thermostat didn't work, have the heater control valve checked, it may not be opening all the way to let the coolant circulate thru the heater core fully.

Unwanted fumes gas in ford falcon futura


is the car on recirculate or fresh air? air from your aircon comes through the bottom of your front windscreen, make sure its clear and free of leaves or anything that can cause blockage to stop it from become damp inside the aircon ducts. if it is definately petrol fumes you may have an exhaust leaking from your engine bay, releasing the fumes into your cabin, that is the most common reason for petrol fumes in your aircon.
