Also check your fan relays, they're located on the left side by the washer fluid in a rectangle black box. If your check engine light isn't on, leave be, they're ok..

In the transmission pan. Drop the pan filter has 2 screws holding it in place. You can't miss it.

check the linkages gear stick to gearbox.

Engine Number Generally found on the front nearside of the engine block!

The fans will not come on till the temperature is above about 90 degrees so it sounds like yours is working ok! The fans will come on as soon as the AC is turned on!

If you already checked the cooling fan system you are a step ahead. If you have gone through all that you have done. you may have a crack somewhere in the cooling system, external or internal.a mechanic should do a pressure check to test for this possibility

EGR is the exhaust gas recirculating valve . It's part of the emission system designed to lower emission of nitrates of oxygen. The vehicles PCM is sensing a problem with the flow or lack of flow thru the EGR valve. The EGR system has several components including the egr valve, erg solenoid, possible EGR temperature sensor and/or a DPFE ( differential pressure feedback sensor) and vacuum hoses. They are located on or near the intake manifold and connects to the exhaust manifold system also.

this relates to the EGR valve solenoisd , the test procedure is as follows . With the ignition on and engine off, use a scan tool to activate the EGR solenoid. Listen or feel for a clicking, indicating that the solenoid is operating. If the solenoid does operate, you'll have to check current draw on the ground circuit. It should be less than one amp. If it is then the problem is intermittent. If it isn't then there is excessive resistance in the circuit and perform the following 1. When it's activated see if you can blow lightly through it. IF you can\'t there may be a blockage causing excessive resistance. Replace EGR solenoid as needed. If there is no blockage, disconnect the EGR solenoid and the PCM connector containing the EGR solenoid control circuit. Using a digital Volt-Ohm meter (DVOM) check resistence between the control circuit and battery ground. It should be infinite. If it isn't, then there is a short to ground on the control circuit. Repair the short to ground and retest as needed. 2. If the solenoid doesn't click as it should, disconnect the EGR solenoid connector and connect a test light between the two wires. Using the scan tool, command the EGR solenoid on. The light should light up. If it does, replace the EGR solenoid. If it does not perform the following: a. Check for 12 Volts on the ignition supply voltage to the solenoid. If it isn't present, inspect the supply circuit for an open, or a short due to chafing or breakage and re-test. b. If it still doesn't operate: then manually ground the EGR solenoid control circuit. The light should light. If it does, repair open in EGR solenoid control circuit and re-test. If it doesn't, replace EGR solenoid.relates to the EGR valve , the test for the exact cause is quite intricate so have copied and pasted the information , keep me posted if you wish

Code 304 means the number 4 cylinder is not producing power. It could be the plug, injector, or other problem.

If it's the original system it's covered in the MPV owners manual that you can download and print, at no cost, here:

If yours is an after-market stereo you'll need to Google it by make and model to locate a manual.

you have a misfire in cilnder 1 and 5 you can check the sparkplugs wires and coils, i hope help you

use the handle of the jack

Sounds like a bad sensor.
