Need help diagnosing Coolant leak

    Hi everyone,

    I have a 2002 sr5 6-cyl, and I have a coolant leak. I'm losing some coolant but not too much, nothing to where the engine is overheating. Opened the hood noticed red coolant dried around every hose connection point, and then noticed coolant leaking out of the top of the radiator and dripping down.

    I'm wondering if I just need to get a new radiator?

    I've heard the stock ones end up cracking or the o ring gives out over time with the plastic ones.

    If someone could give me some advice on this that would be awesome.

    Thanks

    All of the hoses seem to be in good condition. No cracking and the clamps are still very tight. As you can probably see as well I see that it looks like coolant has been sprayed everywhere from it leaking while driving. So I feel like it has to do with the top of my radiator, but I don't know what's causing the dried crusty coolant around the connections.

    Let me know what you guys think.

    Thanks

    Have you ever replaced the cap and hoses? You could try that first, something you'd probably want to do anyway if you replace the radiator. They're often considered preventative maintenance items, radiators, debatable. The cap and hoses are going to be cheaper as well considering that we're not sure it's the radiator. Also, you could pull it anyway and have it pressure tested.

    To me..

    Looks like your clamps are not tight enough. Im not seeing enough squeeze in the tubing for my liking but not too tight. The hoses tho good can still leak. To me looks like your radiator is or near failure. If you have the plastic radiator they fail quickly.

    IMO replace all hoses and radiator but I need more pics.

    Alright I'll think I'll go ahead and just replace the radiator and hoses, haven't done it for a while.

    Do you have any recommendations for a good radiator that won't have this problem again. One with out the plastic?

    Thanks.

    I hate to say it but aftermarket ones are all made in China and probably made by the same company just different names. I have one on my Tacoma with the 5vz-fe(v6) and really no problems been on there 4 years now plus. It's plastic. Most all radiators today are plastic. It's not that it's plastic is not the problem, just like if it was metal it just wears out from all the stress and heat.

    I recommend you replace those clamps just to be safe. They are cheap insurance.
