Repair advice

[Matsui]

I got an oil change and transmissions fluid drain/fill done for my 09 GX470 (260k miles) at Toyota dealer. They came up with a list of issues that some I plan to address on my own and some probably through my independent shop. Their prices were just too expensive and I don't have that kind of money to spend.

1. Clean Fuel System ($294.08) Performed to Eliminate carbon deposits that develop in valve train, pistons, upper and lower intake manifolds.
2. Fuel injection service ($283.17) Fuel system has build up/deposits.
3. Coolant flush ($268.06) Tech found coolant worn and contaminated.
4. Ext Hsng Seal ($1,298.84) Transfer case pinion seal leaking gear oil - worn seal.

I obviously don't want to pay dealer money, so any advice on these especially for #1 - if just adding the fuel system cleaner is going to be enough or if there is anything more to it?

Also, #4 - I'm hoping it is just a seal replacement and not going to be too expensive (parts/labor)? What is actually involved in fixing this and what parts & part number if you know or based on your experience?

Bottle of Seafoam engine/fuel cleaner. Follow recommended guidelines and add to full tank of gas, and in oil. Change oil after about 100 miles.

They also have a spray that goes into the throttle body while the engine is running to clean internals.

Maybe also good time to check/change spark plugs

Drain coolant from radiator. Remove bottom rad hose, drain that. Flush rad with distilled water.

You can also get a garden hose adapter and connect it to one of the heater core hoses. Run for 5 minutes or until clear. Alternatively use a 5 gallon bucket and pump with distilled water.

Have had to flush the heater core on my jeep several times.

Thank you so much for this advice! Will definitely look into it and try it out. I've never added additives to oil, so it will be the first. Have you done this process and how did it turn out for you?
Spark plugs were changed about 40k miles ago so I think it should be fine.

I think I'll let my indy handle this one. How many bottles do you think I'll need. I have 2 sealed Toyota coolant bottles sitting around for 2 plus years. Hopefully they are still fine...

Two bottles of antifreeze should be fine. At least on the jeep it is. Haven't done either on my GX yet. But have done the seafoam on several vehicles in the past. Can't really say if I noticed a difference on anything but it also didn't hurt
