08 leaking engine coolant?

I have had my 2008 tundra in the shop getting the AC repaired. And the mechanic was having trouble fixing the problem then finally realized it was the compressor. He replaced the compressor and the drier. The AC seems to be blowing cold but now I've noticed (after getting my truck back yesterday) that now I'm leaking a good amount of coolant. The leak is coming from somewhere above the drain pan and I can't seem to find where it's leaking out of. I don't have any cracks in the overflow reservoir and the hoses seem to be good. Does anybody know what could be going on? Is it possible that they had to disconnect or remove the radiator or parts to it to replace the compressor and did not reconnect all parts? Any help is appreciated.

 

Thank you. The best I can tell it's coming out of multiple places. Not looking good.

 

Water pump? Gasket going out?

 

I'm with TJ on this. Also, our Tundras are kinda known for cracking the radiator. Regardless, it's a solid place to start.

But i'd definitely be on that shops ass. And if the radiator cracked it's most likely due to improper reinstallation which is the shops fault.

 

Wonder if he's taking to that shop before or check its rating

 

Definitely my thought. I've done a few radiator replacements the Tundra and if a tech is sloppy they can crack pretty damn easily.

Unfortunately, our radiators have cheap plastic on the top and bottom. Hairline cracks happen due to pressure issues, weather changes, and improper coolant levels (overheating), not to mention it becomes brittle throughout the years. Also, check to see if your coolant cap is bulging or concaved - this could indicate previous stress on the radiator which could have caused it to crack under pressure.

 

I wouldn't say it's much of an "issue" but over the years more and more manufacturers have turned to using plastic making them more prone to failure. haha Regardless, it's not a terrible replacement. And replacement parts are found for pretty low prices. Just keep your fluids in check and you'll be peachy.

 

Water pump on my 07 27k on it

 

That's just unfortunate! You shouldn't have to deal with that until you are due for a timing belt.

 

That was 2014 so it already 7 years old (bought it with 17k in 2013), it was quite the repair job,took me about 4 hours. PS no timing belt in the 5.7 to ever change

 

True... Poor 4.7's. Gotta love dual chains.

 

Smh.. they still go slack and still can break ask Nissan and there problems....

ask any 22r/20r engine what the problem with chain was tick tick tick and the god damn guides going out... Fun I own a 22r.. tick tick tick.

 

My (pink) coolant is low after doing a engine check (2008 5.7).

No signs of leaking.

Can I use regular auto store coolant?

GM Dexcool is also pink...... can I use that also?

Pentofrost Antifreeze/Engine Coolant????


What's the verdict?

 

Stay with OEM ...DO NOT MIX

 

i keep with toyota brand coolant... ebay's been the cheapest place i've seen it. A buddy of mine who's super nerdy looked in to the chemical side of things and low and behold, Toyota coolant is slightly different. I didn't bother double checking, just took his word for it and bought red stuff.

 

Thanks all.

I was about to go buy the pentofrost from advance Auto. ..... will spend the extra “mulah “ from the stealership
