check your heater hoses one connects to the intake on rear passanger side of the motor it is likely the intake cracked there is a recall on this issue if the intake has been replaced with factory intake it is possible that the intake gasket is leaking check the bolts to be tourqed to specs if gasket is leaking replace gasket

Crown Victoria Plastic Intake Manifold Heater Leak Fix

When the stupidly designed intake manifold cracks where the heater pipe sticks into the plastic here's how to fix it. You will notice the plastic around the heater pipe is connected to some plastic to the front of the car from it. Take a hacksaw blade and cut about a 1/2" groove in that plastic - just enough to get a hose clamp around the plastic circle that holds the pipe. Tighten the clamp and voila! No more leak.

In Utah, a 2010 Crown Victoria will run you approximately 29k. Although with a few more features a 2010 Crown Victoria could run you closer to 31k.

Antifreeze if you get an internal leak in your engine it could ruin the motor

There are several reasons why a Crown Victoria will not start. One reason could be a dead battery. Another reason is that the spark plugs and plug wires may need to be changed.

Check the M.A.F. ( master air flow ) on the intake. This could be a factor.

Thermostats determine when antifreeze enters the main cooling system. If the thermostat isn't working correctly, the antifreeze could enter the engine to late, (or not at all) resulting in an over heating engine. Another problem of having antifreeze enter the engine late, is that if your engine is very hot, possibly a little warmer than common, when the antifreeze enters the engine, the cold fluid could cause the engine block to cool down quickly, causing a cracked engine block.

could possibly just be your C.V. joints

An engine cylinder MISFIRE has been detected on the ( # 3 engine cylinder ) firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of 1998 Ford Crown Victoria ( 4.6 liter V8 ) ( I'm not a mechanic / technician but it could be the sparkplug , the individual coil for that engine cylinder , a problem with the fuel injector for that engine cylinder that is causing the air / fuel ratio to be incorrect , or maybe some other problem )

Engine overheating could be caused by several reasons. Some of them are, thermostat, faulty fan, faulty sensor, bad rad., blockage somewhere, water pump.

you might have a blown head gasket and the coolant is leaking into the cylender and the engine is burning it.

User Avatar

Heater hose has a leak, freee plugs expanded in freezing weather because not enough antifreeze , engine block cracked or a blown head gasket.

Ford Crown Victoria. Or some names are Porsche and Mercedes...

There could be quite a few reasons why the car won't start. If cranking or turning over the engine is the problem and the starter is good, it may be the battery. If the engine turns over but won't start you have bigger problems...

Could be a few things. Does it leak antifreeze? if so, fix the part that leaks. If not, you could have coolant mixing with oil inside the engine, which burns it. check your spark plugs. If they are white, you are probably burning antifreeze - fix immediately. your exhaust will smell "sweet" as well if you are burning antifreeze.

Antifreeze does 2 things. First it protects your engine when the outside temperature is below freezing and the vehicle is not running. If the coolant freezes it could crack your engine block requiring a new engine. Caution: 100% antifreeze will also freeze up if it gets too cold. For best results you have to mix antifreeze and water. Check the antifreeze container for correct mixture. Antifreeze also has other things in it that keeps the water pump in good shape, prevents corrosion of the the radiator and helps transfer heat out of the engine. You need it even in hot weather.

It is possible that the antifreeze is coming from a bad water pump. Clean the engine off. Watch it to see where the antifreeze is leaking from, as it could be a hose instead of the pump.
