coolent leak

It's the infamous plastic coolant crossover leak... Does your plastic intake manifold have the plastic coolant crossover? If it does, then there is your problem.

See my sig for replacement pics.
 
ok my engine is totaly stock besides intake so im pretty sure its the plastic intake etc. what parts should i buy to fix it and should i be worried about a rebuild?

No, you need not worry about a rebuild. The intake is not difficult to replace.

You have some choices. You can buy the updated NPI intake with an aluminum crossover. You can buy the PI intake but it needs adapter plates ($$) or some installation tweaking (RTV dabs in the proper spots) to get it to seal just right. The NPI intake is quite restrictive and the engine power output is limited by this intake. The "PI intake swap" is a very popular modification and it is well documented in many, many threads here and on other Mustang boards. If you are mechanically inclined, I suggest that you go with the PI intake. If cash is tight then the cheapest option is the NPI intake with the aluminum crossover.

The coolant may have gotten into the sparkplug wells. If it has then the engine will develop a miss. At least you know what to look for. Sop up what you can with shop towels. Get a can of compressed air (keyboard cleaner at Office Depot/Office Max/Staples/etc.) and blow out the remaining moisture. Dry off the sparkplug boots and put a tiny dab of dielectric grease in the boot and swab it around. Just be careful pulling the boots off because you don't want to break a wire.

I will try to find some threads for you to read. Somebody here did a nice write-up, complete with pictures.

There is a heater hose that goes right down the middle of the V, underneath the intake manifold. While it should be fairly reliable because it is mostly hard line, be sure to check it and the rubber hose going to it at the back of the engine.
