Here’s the latest reader question, along with my reply!
Gary asks: I need one of these and a monkey wrench was thrown in. I was ready to order and it stated not correct if coolant heated PCV. How do I find out if mine is coolant heated?
My reply: Your ’04 has a plastic intake manifold and I think what you’re referring to by “coolant heated PCV” is just that – the plastic (PCV) is heated by coolant. This refers to the passages in the intake which flow water (coolant). I’m pretty sure this manifold is “one piece” (some intakes have separate sections) and I think the gaskets are integral.
Do you have a shop manual for this car? Do you have the correct OE or aftermarket replacement intake for this car?
I don’t think Lincoln (Ford) made different intakes for the ’04 4.6 in the Town Car – so as long as you buy the correct part, with the correct pieces to install it, you should be all set on that score.
But be sure you know the procedure before you start work. I can’t emphasize this enough. Do not just “dig in.” Know what you are about to do – and have a reference manual handy – before you begin taking anything apart. And know exactly what to do before you begin putting things back together! Especially assembly order and torque specs – very important with aluminum and plastic!
Finally: Take your time. Don’t get impatient. Take pictures before disassembling – so you can refer to them during re-assembly, if need be.
There are many videos on YouTube that may be helpful, too. Here’s one:
