Unhappy 1994 Mustang V6 3.8L Engine Problem - Please Help

Hey guys, first time poster here.

I have recently bought my 1994 V6 Mustang and following a replacement Coil Pack, I am now having an issue where it appears that the engine is overheating.

The water temperature is right at the top of the guage, the engine is labouring at around 500-600 rpm, and (bizarrely) the vents only blow out cold air, even when the heat is set to full.

The car seems to drive fine, the radiator coolant is topped up, and the oil level is well within acceptable limits.

Any ideas you guys might have about what this could be would be greatly appreciated, as I've only had the car around a month and a half and I've yet to experience it in normal driving conditions.

Cheers in advance,
John

it could be just a bad sensor....

Check to make sure your fan is kicking in. You could also try replacing the thermostat before you do anything more major. (Like a water pump)

I agree with schreiber. Make sure your car is actually running hot first......

Update:

Both head gaskets have blown. Anybody know any decent places in the Manchester region to get such work done?

I have a current quote of 600 labour and whatever the parts cost.
This is, of course, before I find out what the actual cause was.

Didn't Ford have a recall on the head gaskets for 94-95?

I believe it was those years that had head gasket problems.

no, but the 98's are known for blown head gaskets. you shouldn't have drove the car until you diagnosed the problem. anyway, the gasket itself is a cheap piece but you're looking at around 2000 in labor just because it's hard to get to. if you have any friends that are good with cars, now would be the time to ask a favor.

Fly me over from Oslo, Norway and I'll do it for free (food and drink). I've done the head gasket swap on my '95 twice. I'll use a weekend.
Hell, I might have a pair of head gaskets in my toolbox already as backup, hehe.

It's not much parts needed. Gasket set and new head bolts.







The 94 - 95 does have a recall for head gaskets, but I'm not sure if Ford Europe (which is German) will fix it.

When I think of it, I've changed out those head gasket 3 times, thanks to "Brand name D". Not going into details, but had to fix a little issue with one of the heads.

when they go about fixing the headgasket issues isnt the prescribed solution to do something with deepening the head bolt holes and stuff?

The vents were blowing cold because here was air in the cooling system.
