Still running your original radiator? CHANGE IT!!!!

If you haven't changed your radiator yet take my advice and avoid a huge mess and alot of money and change it. My transmittion cooler inside my radiator exploded and I now have my tranny full of anti-freeze and the rad and engine block full of transmittion fluid. I had to replace the rad and flush both. What a mess and alot of money.

Has anyone lost a transmittion due to this problem?

The truck is a 2000 with 135k. I keep up on all maintenance and this totally caught me off-guard.

Re: Still running your original radiator? CHANGE IT!!!!

I changed mine out last year due to dropping a drill with an extended bit into the side of it, (I know, dumbass CJ move) but other than that it still looked good. As long as they look good, and you do a flush every 2-3 years, you should be fine.

Very valid question here.

Toyota Red is what needs to be used.

Re: Still running your original radiator? CHANGE IT!!!!

Yes I always run toyota red and when I changed the timing belt I flushed and pulled the radiator. It looked brand new inside, I figured after 90,000 I would find some scalling inside it. Clean as new...

Re: Still running your original radiator? CHANGE IT!!!!

More info please:
Do you tow anything?
Has there been any coolant leaks or weird smells from the exhaust?
Overheating?
Mine (a 2004 DC) has 235K miles on it and it still looks fine (Toyo RED has only been used).

Maybe you can take the old radiator apart and do a little detective work.....see if you can pin point what failed......and post some pics.

Re: Still running your original radiator? CHANGE IT!!!!

I have not seen much on this forum about radiator failures. So I am going to assume that they are rare. I think I will take some risk and not replace mine. It looks fine.

Re: Still running your original radiator? CHANGE IT!!!!

I have seen this a few different times, it's not common but it does happen. Usually too late by the time people notice, ends up causing transmission damage, $$$!

Re: Still running your original radiator? CHANGE IT!!!!

I towed a Ski Nautique with it for one year. Just in the summer time about 30mins each way. I never have had any problems with overheating and when I did the timing belt I replaced all of the hoses after the inspection of the rad.

It was an internal failure of the tranny cooler. Sorry to say I don't have it anymore, on garbage night I put it out at the curb and one of the scrap metal pickers grabbed it. Here in MI we have scrap guys come around ever garbage night. Nothing stays at the curb very long.

I was working as an aircraft Mech for several years and have rebuilt everything from snowmobiles to boats and sport cars. I keep up on all preventive maintenance on my equipment. This thing just blindsided me. No hint of trouble before it blow.

Re: Still running your original radiator? CHANGE IT!!!!

04trdtundra, I will let you know if I end up changing the tranny. It slipped on the way home when the radiator split. I only had about a mile left to get to my driveway. Hopefully it will be ok.

Re: Still running your original radiator? CHANGE IT!!!!

I just bought my '00 with 132K on it about 3 weeks ago. One selling point the seller repeatedly made was that he had recently replaced the radiator. Yup, it was definately new....Then a week or so later, I checked my reservoir, and found about 3" of foamy orange sherbet in the bottom. you can read my post in the Engine Drivetrain forum about it.

Soooo I'm guessing this is what happened to mine, and the A-hole never flushed it properly.

Re: Still running your original radiator? CHANGE IT!!!!

Stone Blue,

Yup thats what happened, it took several cycles to flush all of the orange sherbert out of my cooling system. I added some degreaser and to help break down the tranny fluid and then flushed it two more times.

How is your tranny shifting?

Re: Still running your original radiator? CHANGE IT!!!!

Hard for me to tell...I've never owned an auto..
It gets the job done....But not having driven it BEFORE this happened, I dont know if its supposed to be "snappier" or not.....The ATF in it looks fresh, but that doesnt mean the PO didnt just flush & fill it afterward....I hope to pull the pan soon, and look things over.

What did you use for degreaser?....I tried simple green on the reservoir, it cut it some, but not good enough... I used Engine Bright spray to clean out the reservoir, and that did a great job with just shaking it........Not sure I want to use that in my coolant system though....I saw Gunk has a liquid Degreaser, but I havent been able to find it locally.
