Question about 1996 Ford Thunderbird LX

96 Tbird misfiring cyliner #4 with leaking coolant

The other day i first noticed a very noticeable clunk and hesitation while driving. At first i thought it was the tranny or tourque conv. I had it hooked to a cpu at autozone and they said my #4 cylinder was miss firing. I was told to replace the coil pack, spark plugs, and plug wires. Well ive yet to replace them. Reason being, i pulled the #4 plug out to investigate. When i pulled the boot off the plug it was coated in coolant and the cavity the plug is in was filled with coolant. I then took the plug out and it didnt appear to have any coolant on it and looked to be in good condition. I just replaced the plugs a month ago. My question is, where is the coolnt coming from? Im hoping its just and external hose leak or somthing and not something more serious. And also, ive drove approx 100 miles with it like this. Will that damage nething? Its a 1996 Ford Thunderbird with a 4.6 Litre V8. ThankYou

    If it was a leaking head gasket wouldnt it be in the oil? Ive only seen the coolant on the outside of the engine. With the spark plug still installed there is coolant in the hole on top of the plug where the boot connects to the top of the plug. Thats why i was thinking and hoping it was just a hose or something located near the plug leaking. I dont know.

Engine over heats while driving but cools down at idle

while driving coolant will cool down because air is flowing across radiator at idle no air movement ---check fan operation as well----- but until you fix leak you will still over heat due to lack of coolant and pressure

Overheating and leaking coolant

Depending on the car most cooling systems on late model cars have an air bleed valve on the cooling system usually on or near the thermosat housing. When filling the cooling system it is necessary to bleed the air from the system to avoid an air pocket that may develop in the cooling system. I am curious as to why you would think it needed coolant from hearing a clunking sound... And you still need to address the original reason it needed coolant...

It sounds like the engine has a bad vacuum leak, they are very problematic for a leaking intake gasket. This usually would be accompanied with coolant loss, but not always. Other causes are loose air plentum snorkel (if air filter recently replaced) or a leaking vacuum hose. It could also be a sign of a computer problem starting. It would be best to have a technician or parts retailer scan it for you to narrow the problem down. The clunk noise maybe unrelated or possibly engine noise(like an intake issue), check the oil and coolant levels first.

I have changed plugs using the platinum plugs and the problem don't go away. These plugs can make a car run worse in some cases. I have found it best to use the OEM or a step above on 4 cylin and 6 cylin engines. The Plats work fine in 8 cylin engines. You could also have a bad plug wire. The plug wire could be jumping spark. At night, open the hood, start the car with lights off. Look around the plug wires for sparks jumping. If a wire is bad, the spark is leaving the wire and grounding itself to the nearest metal causing rough engine idle and misfire.

I too have the same problem on my 2005 1.8t B6. I noticed a hole in the breather hose coming off the valve cover that runs to another port under the intake manifold. I have the hoses on order and should be here on Wednesday. I'll post again if that fixes my problem.

This sounds like the heater core radiator has a leak. After disconnnecting the negative battery terminal and draining the coolant, you will have to perform the following:
1) disconnect the heater core hoses.
2) remover right side sound insulator and glove box module.
3) Remove the programmer shield, if equipped and disconect the air mix valve link.
4) Detach the programmer vacuum and electrical connectors.
5) Remove the heater core cover, leaving the programmer attached.
6) Remove the heater core retaining screws and the heater core.
7) Take the heater core to a radiator shop for repair and re-install.
