4.6L manifold leaking coolant. To repair or replace?

Hi All,

Typical problem...coolant leak in the manifold near the coolant temp. sensor. Its a small leak. My question is that should I replace with a new manifold, repair somehow, or let it be? my concern is that with the freeze/thaw of winter it could get worse and leave me stranded. Car is 99\\' with 142K, nothing special, I just want to keep it running. If needs replaced, I\\'m looking to do it myself which I\\'m excited to do, and if i go that route, are there other improvements that I should make wile im at it? (clean throttle body, new wires, plugs, injectors?)

Any insight and advise is greatly appreciated!

A coolant or oil leak usually is telling you it is time to work on the engine. Water and oil are the live blood of the engine. Loose those and the engine dies.

It is time to replace the intake. Go to www.crownvic.net and there is a good write up about replacing it. Just take you time and follow the steps.

Afterwards check the old manifold and see if you have a crack in it. That is usually the problem that causes the leaks.

And have a Happy Thanksgiving.

JD,

I am currently trying to set up a Crownvic.net User name. When I did it sent me to Supermotors.net. I signed up (which is how I am replying to you) but I still cannot log into Crownvic.net. To make matter even more frustrating, there is not help section where I can email moderators (at least that I can find) if you are not a member. Any chance you can point me in the right direction?

My issue is the standard P71 Intake Manifold being made of plastic and needing to be replaced. That is the major primary issue. A secondary issue is one of the (2) Upper Radiator Hose Inlet bolts is broken.

Thanks for any assistance,
