Question about 1997 Ford Explorer AWD

1 Answer

Possible cracked block on 1997 ford explorer

The test was some kind of Hydro carbonation test where they use some type of dye and it causes the antifreeze to change color. It failed this test once and they thought that my radiator may have not been flushed when the other guy installed my new radiator week or so before. They cleaned it and it failed same test 2 more times. Said I was loosing compression and had internal leak. I know they have as well ran a compression test on it. Said my water pump and thermostat is working.

An error code of 0457 came up. any idea what that is?

P0457 FORD - EVAP Control System Leak Detected (Fuel Filler Cap Loose/Off)
EVAP control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly.

Vehicles that meet enhanced evaporative requirements utilize a vacuum-based evaporative system integrity check. The evap system integrity check uses a Fuel Tank Pressure Transducer (FTPT), a Canister Vent Solenoid (CVS) and Fuel Level Input (FLI) along with the Vapor Management Valve (VMV) or Electric Vapor Management Valve (EVMV) to find 0.040" diameter or larger evap system leaks. Federal vehicles can utilize a 0.040" leak check rather than the 0.020" leak check required for California vehicles (click over pic for zoom).


- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors

Possible causes:
- Missing fuel filler cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap

Possible solution:
- Retight or replaced fuel tank filler cap

Tech notes:
It is a very common problem with Ford vehicles. There are service bulletins for the following vehciles:
1997-2000 Ford CONTOUR
1997-2002 Ford ESCORT
1998-2003 Ford ESCORT ZX2
2000-2003 Ford FOCUS
2002-2003 Ford THUNDERBIRD

Would like to know how to determine if I need to replace my cylinder head or if it is the gaskets, I got white smoke coming from exahust and going through antifreeze

Hi, we are never sure if the problem is the gasket or a cracked head until the head is removed and pressure tested for a crack. Oftentimes, we remove the head carefully to preserve the gasket as much as possible so that we can inspect the gasket for leaks. If it is obvious that the gasket was leaking based on visual observation of breaks in the gasket, then we may skip the pressure test and just replace the gasket; however, there is no way of knowing until the head is off the engine.

Vehicle cooling system loosing water, foam in engine oil and had a new head gasket 9 months ago

Seems as though once again you are in the blown head gasket or worse situation. This can also be a result of either a cracked head or block. There is a dye test that can be performed on the head once it is removed, the block would have to be magnafluxed to make sure of no cracks. The later requires complete engine rebuild.

1997 ford explorer check engine lite is on.Code says low pressure in egr but ive replaced the egr valve and egr pressure sensor no luck

you probably have blocked passages in the intake manifold. remove the egr and check the port for a clog. you can scrape most of the carbon out with a pick or screw driver and then use some spray carbon cleaner in there. also check the metal exhaust line to the egr

89 nissan pulsar vector (auto),overheating problem.Had Thermostat & housing changed because they were corroded,also radiator hoses have been replaced.Flushed out the radiator & filled with fresh...

well any thing near to the red could and most likley would crack the heads, if there not all ready cracked!
if the gear box is working fine and it drives ok
i think you should first look at your water pump but you may have a blown head gasket thats why it boiles up on you could take it to the repair shop and ask them to do a " snifer test" it checks the water in the rad to see if there is any hydro carbon's in it if there are its a head gasket blown or a cracked head!
these hydro carbond's come from burning fule only and if any hot gases from any head gasket's or cracked head's are getting into the water jackets there will be some in there,,
its a common test to do first,,
it turns the test blue or red! then have a compreshion test done that could also pick up a blown head gasket
what ever happens you must not let that engine get over heated or it will do far more damage than just crack the heads ,,,,,,,and if im right
(which i think i am) when that gasket go's pop it will boile over in seconds not minuets watch it closly

Engine overheating

good morning and welcome to fixya
how hot is the engine temp reading? you need to make sure that the water pump is actually pumping you should be able to see the coolant moving past the radiator cap if you remove it. is the vehicle losing coolant? you might want to take the vehicle in and have a block test done on it, this will check the hydro carbons to see if you possibly have a blown head gasket or a crack somewhere that there shouldn't be. please let me know so i can assist you further. thank you again

please rate this solution??

Possible cracked block or head

A cracked block often results in oil in the antifreeze. A cracked head or blown gasket is often heard while accelerating plus it my chug or miss. Take it to another garage and get the system pressure tested. I am not sure if thats what you meant by "a carbonation test". Check for milky looking oil on the dipstick first. If its normal then have the garage inspect the head for leaks using an ultraviolet light around the heads. It may a clogged rad or a faulty water pump too, even a faulty rad cap. Let me know any more info when this is checked. I hate to see someone ripped off.
