Tundra leaking coolant

Hey guys I recently changed out my timing belt and water pump on my 2000 tundra 4.7 and it ran great but out of nowhere it started leaking coolant I can tell it's from the water pump because it was seeping behind the alternator and I looked above the engine and see coolant splashes around near the water pump and throttle any advice on how to fix it it just over heats and leaks a lot of coolant

 

I think you’ll have to remove the water pump and reseal it. Get new gasket and rings. Also don’t forget the FIPG.

 

Thank you will let you know once I fix it

 

Keep in mind it looks like you're running the incorrect coolant (green). That's not what our trucks require. You'll want to flush that old shit out and get the correct coolant in. The 4.7L has to drain plugs on the engine block for this.

 

Ah shit well I didn't know that all I did was put in Prestone ready to use I didn't know if there was a specific type of coolant I needed

 

Yeah and if you mixed it with existing pink, that's even worse for the system. Can lead to bad things.

 

No I drained the old one and oil as well when replacing the timing belt and water pump

 

When I swapped my Timing belt and water pump, mine leaked too. I had reused the factory radiator hose spring clamps and they'd lost their spring. Replaced with new hose clamps and no more leaks.

 

Was it leaking the same area as mine?

 

No idea from that one picture, but I didn’t see it coming out of the hose fitting since it was underneath, just saw all the wet stuff below it. Just saying it’s worth checking those connections before tearing back into the water pump

 

We do have a lot of “common coolant leaks” I. The megastores, 2nd reply with nuisances: https://www.tundras.com/threads/so-you-wanna-buy-just-bought-a-1st-gen-tundra-eh.115928/

• Coolant leaks: Three common causes: One is the is the gasket behind the thermostat housing, another is the coolant crossover at the rear of the block, and last but not least, old radiators is another source. Here's a list of things to check if you're losing coolant. For repairing the leak behind the t-stat housing, check this out. For the coolant crossover tube issue, you'll likely find coolant at back of the block, near where the trans and engine meet, check this reply for video/fix. This post is for leaks at t-stat housing/inlet neck. This replycontains links to three other off-brand/odbball leak cases. For radiator leaks, this is one example of a tiny one - always replace with Denso brand radiator, and know different cab types use different sizes, careful where you order, scAmazon especially tends to deliver damaged products often (RockAuto has a spotless record with forum members). Proactive radiator replacement is wise. The transmission line routes through the bottom of the radiator ... golook up "pink milkshake", ithappens in these trucks.
