Hi again all, so the reason Im making this a new topic is I wanted to focus on the upcoming job of replacing my intake and plenum gaskets on my 01 Dodge Ram 1500. It has 165k on her clock. It’s the ex cab short bed 4×4 auto trans and 5.9 Mag V8
Im actually excited but a tad nervous about the job. So Im wanting to get all the advice and thoughts I can get on it before I get started. It maybe a little while yet as I need to acquire a few tools and of course the Hughes upgrade kit.
To catch y’all up within the last 6 months Ive done the following on the truck
New Brake line, pass side caliper, brake pads and rotors (August/Sept. 2014)
Oil Change (160k August 2014)
Trans fluid/filter change (162k Sep./Ot 2014)
Power Steering Pump (Dec. 2014)
Bleed cooling system (Nov 2014)
Tune Up (Spark Plugs Oct. 2014, again last month, wires Oct. 2014, Cap and Rotor last mont)
Pass side front wheel joint last weekThats all I can think of for now.
My plan so far is while Im changing the intake and plenum gaskets I will also do the following.
Check and replace drive belt if neccesary
Clean Idle Air Control valve
Bench clean fuel injectors and replace O-Rings (any thoughts or suggestions on how to would be great)
Check torque on rocker arm bolts, replace valve cover gaskets
Flush and change oil and coolantA question I have is for the coolant can I run a coolant flush, drain the radiator, refill the system with water and redrain it, then refill with antifreeze? Or do I not need the water step?

Chris see if this helps. If you don’t have rust in the system just drain and refill.
If you do have rust use the flush. drain the coolant refill with water (distilled) run
the flush. drain. refill with water run drain. then fresh coolant. I would replace the
thermostat while at it.Thiose are some of the videos Ive watched College Man, but I appreciate the thought. My coolent looks realitively fresh.
Good luck with the work. I’ll just add this. So many times I’ve seen things go south due to the best of intentions. In other words, “if it ain’t broke, don’t fix it”. To put a finer point on it, I would advise staying away from things like cleaning injectors and tightening rocker arms. Things like that can lead to trouble if you’re not in there to actually fix something.
Once again good luck.
Good point Eric. One of my other issues of debate is if I want to pull the radiator out. Ive been told it would open up even more work but again itd be adding to the time and chances of something getting broke. Although ive heard stories of the radiator getting crushed or hit whilst working on this particular job.
A 2nd question I just came across is Im not due for an oil change until 167.5k or so. The truck is right around 165k right now. My question is with this job is an oil change really necessary? I was thinking yes as Im sure coolant might get mixed in with the oil while doing the job
Hi,
I did my 3.9 Hughes kit last summer. About 140K miles on the clock. I posted what I thought important here. http://www.ericthecarguy.com/kunena/common-problems-pattern-failures/50534-94-02-chrysler-3-9-5-2-5-9-engines-intake-gasketOn the oil change; when I put it back together I drove it a few hundred miles then had the oil changed after running an engine cleaner through it. I had no problems with the radiator and the V8 has more room. I also did the Timing chain and added the tensioner they failed to use when first built.
I had the throttle body and the intake tanked and I have all new sensors on the intake and TB. Whatever is down under the AC on the top front of the motor should be replaced even if it looks good just to avoid having to take it all off again when it does fail. It really improved gas mileage.
Good LuckI appreciate the input I didnt think of the timing belt for my truck. Tho its not making noise tho Im pretty sure im close to being due for it
