3.0L 12V Timing Cover Coolant Leak Repair

Now this is one of the most common leaks on a Taurus that we see. They start off slow but I have seen them go all out with a rapid loss of coolant. If yours has this issue and have been putting it off here is the definitive how to video to get it sealed back up with a few tips and tricks to make it all a little easier. Hope this helps........

You are very knowledgeable and make it look easy. Thanks for sharing with us. I fear I will be doing this repair for the second time soon. I've got a slow drip starting again on the top of the cover because a strip of the gasket broke away.

If you follow it step by step and take your time it is easy enough anyway. Much easier than the new engine front covers like the 3.5L what a pain that is.

What did you use to clean the engine block surface, it's the best cleaning I have ever seen and I have done the job twice on my two Taurus.

Scraper to get the big chunks of the paper gasket off, then die grinder with 3M cookies on them then a final polish with scotch brite get them nice and clean and smooth. You just need to cover the exposed engine components like the chain etc so they don't get no grit then a thorough cleaning.

So what pad do you use that removes the gasket material not the aluminum. I have to say I am a bit leary of using the die grinder on gasket surface even though I love it with sanding disks for many tasks. I know pro guys do though. I would actually love to see a video of you doing this. Sometimes the darn gasket clean up takes as much time as turning wrenches.

^^^ its also the most important part or the job. I was not aware of the issue with using RTV on both sides of a paper gasket.

I have always used RTV on both sides of gaskets without issue myself, but I guess I could see how that could under the right case could let a gasket slide out. RTV does make the cleanup for a later replacement go way easier then the first time where just a paper gasket was way backed on the parts.

The guys in the Corps used to use it and split gaskets all the time, then again maybe that was them over tightening them but I have heard the same from automotive teachers back in the day.

Great video makuloco! After cleaning the engine and driving it around for a week I ran across your video while trying to see what part was left off when I had my compressor replaced. The O2 sensor connectors are just dangling and I can't see where they go.

Anyway, I checked that rear top portion of the timing cover and sure enough it's just a little bit wet. I've had to add water to bring the level from the middle to the top line of the reserve once or twice a year since the car was new (which is normal) so I never even thought to check. The job doesn't look too difficult, just tedious. What is the book time on it and how long does it take you to do it? Thanks!
