3.4 water pump and thermostat.

How long did it take for you to do this yourself.And difficulty level?

 

Both answers will vary widely based on the experience and skillset of the person answering.

 

Well I'm not a mechanic but pretty inclined and generally do tasks myself.On the house cars ect.But this 3.4 is kind of a pain.I bought the parts this evening and wondering should I tackle this job myself? Any help is very appreciated.It may sound dumb but I've never had to do a lot of work on a 3.4.

 

3 to 4 hours with the proper tools, space, and know how

Tackle it yourself. When you tag team, things tend to not get tighten or you end up with misc parts leftover.

 

Thank you! What are the preferred proper tools.I have a bunch of tools,but any specialty?

 

Nothing specific, no special tool needed to change the timing belt/water pump. Just a complete set of socket (having the correct size - 3/8 to 1/2 drive), metric allen socket, breaker bar, wrench/gear wrench, and air impact.

 

Having a crankshaft pulley tool helped a lot when I did my timing belt and water pump.

There's a good sticky here to make your own if you don't have one or want to buy one.

Should I just do the timing belt while I'm there? Don't think it needs it but hey

 

That too on some engine. But all the 5vz i worked on, glad i didn't need the tool

 

I would. Why do double the work. Judy but the complete kit with hydraulic tensioner etc

 

How many miles since it was done?

 

for curiosity... when you pull the lower hose / thermostat housing off note if the jiggle valve on the thermostat is in the 6 oclock position or not.

I am curious to see if you notice a lower operating temp IF it was at 12 and now it is at 6.

 

Search there is alot of info on this. Guys just recently talking about it as well

 

Oh yeah? No need for the pulley tool?

 

Hmm I've heard 6 and 12.Go with 6 eh

 

I'm not sure a guy owned it before me

 

12 o'clock position for the bypass. Air rise in coolant, keep that in mind. So placing it at 6 o'clock, it won't be any good

 

If your air impact can remove the balancer bolt, you don't need the holder.

 

FSM states 6 o'clock

I'd just block off an entire weekend if you can. You will be learning as you go. I'd watch the Timmy time video first and maybe have it going while you do it!
