I got a 2nd gen with 195000 miles im thinking about seafoaming it. Jus wonderig if its a good idea and if soo how would i go about doing it?? Hope someone can help.

 

Worked wonders on my previous car ('99 Toyota Solara SLE)... Went from not being able to break traction to being able to do semi-decent burnouts. I have yet to try it on my Bimmer or my GF's CL.

 

As far as your car, yes, I would highly recommend it.

 

Yeah, many TL owners have used Seafoam and have had good luck with it.
There are many previous threads on how to use Seafoam. Check the 2nd Gen's DIY sticky for more info.

The simplest method is to just put a can of it in your gas tank. Some use it in their motor oil before a change. Others have used in through the vacuum line for the intake. Search and read up on what procedure best fits your needs.

 

Seafoam is a cleaner. And yes it does everything as advertised. I would recommend a 1/2 can through the vacuum line before a spark plug change, 1/2 can in the crank case before an oil change and 1 can in the gas tank when almost empty.


It will clean the gunk out of your oil, clean any moisture build up in your gas lines. Through the vacuum lines it will clean a lot of carbon deposits that have accumulated over time.


All this equals a better driving car.

 

What if i use it after an oil and spark plug change? Kz i just changed all that out

 

For the spark plugs: No HUGE foul since there isn't any corrosion/deposits for the dirt knocked loose to cling onto, but still recommended to do so beforehand... In other words, still better than Seafoaming at 75% of your spark plug's life and driving it until it's at 100%.

For the oil change: I'd wait until your next oil change since you don't want all the deposits that have been knocked loose to float around in your oil and quintessentially making that oil change useless.

 

Ok so maybe waitinn would be a better approach. I mighr aswell just clean the egr valves

 

I would say yes. Wait until the next oil change. But beware, every time I put seafoam through the vacuum line you will get a lot of smoke, so try to do it in well ventilated area. Not your garage. After seafoaming through the vacuum line also let sit for up to 15 minutes and then driving down the road at WOT until you don`t see any smoke left. It also might throw a code, don`t worry it will go away.


I would also recommend:
~cleaning the throttle body
~lube the hinges on the throttle plate
~clean the egr passages and egr valve
~clean and lube the throttle springs
~remove and clean the iacv valve

 

What fluid would be best to clean egr passages and throttle body?

And would cleaning the intake manifold make a good difference?

 

Throttle body cleaner for the throttle body.
Brake cleaner, deep creep or seafoam spray for the egr.
All purpose oil and q-tip for the throttle plate hinges.


Intake manifold, yes.
