Coolant leak by trani? 1st gen 4.7

Hope that fixes your problem! And once you have free time, we need to hear more about your intake setup. TB spacer? Air intake tube?

 

Thanks knabors! The tb spacer & air intake were done by the previous owner along with the front bumper but i would have upgraded the same exact things so it was nice already having it done. Unfortunately I’ve never driven one without a cold air intake so I can’t speak for the difference it makes.

Everything I have done to it since I bought it back in 2018 is
- Vinyl floor
- touch screen radio
- 12” sub
- topper and I installed rails on top that have a couple light pods on the end (not hooked up yet)
- hi-lift mounted on the front bumper
- aftermarket light pods on front bumper
- new grill(not to happy with the one I have)
- blacked out some of the silver trim
- 2.5” leveling kit.
- Level 8 17x8, -10
- Pirelli scorpion mtr’s (they rub just a little)
- 1 1/2 supreme wheel spacers
- weather tech plastic on the hoods and the windows (it helps for the front windows but is only for looks in the back lol)
- Gibson exhaust manifold

and small things here and there. If you want any pics of anything lmk. It was my work truck for painting but I’m switching jobs so i don’t have to worry about getting it that dirty anymore and I can upgrade it the way ive always wanted to. I would have upgraded it while I used it for work but how many painters do you see roll up in somthing that looks like it belongs in the mountains? Lol

 

Also no local auto part stores had the gaskets I needed so I will give an update on the coolant leak tomorrow

 

If you had Toyota coolant in there and mixed it with regular green/yellow you may want to consider a flush soon. From what I've heard organic acid coolants like Toyotas and regular coolant don't mix well. The Peak OET line of coolant for Toyota's is good stuff. I do think theres a type of valvoline coolant a lot of people on here use though that is cheaper. (I think that's the brand anyway)
Hope you get your leak sorted.

 

I agree NickB. I’ve been doing a lot of research and read about that. I was afraid to top it off at the start but the can said it’s meant to top off different kinds of coolant so I figured it should be okay for at least a week. I’m going to do a flush on mostly all the fluids very soon

 

There is also a rear water bypass with a gasket on each connection. I had a leak here on my 02 Sequoia. You can see it on this video:

thank you for the info seth. If messing with thermostat housing doesn’t resolve the issue I will try this. I need to wait 24 hours for the RTV to set, flush the system and refill it then I’ll know for sure
