Little history. We've been fighting this for about 3 years, runs hot under a load. changed thermostats twice, foam is sealed around rad, rad is clean, checked timing and so on. Last spring we took the rad in to have it rodded. Put it back on and did some field work with it and it did fine, temp wise. We thougth problem solved, no not yet. We had it on the grain cart last fall and did fine. We had the motor front cover oil leak fixed over the winter, field ready, right? So this spring 20 minutes after pulling in the field it starts warming up again. Yesterday I decided to try again. Pulled the exhaust off looking for a problem. That looked ok. But the aspirator line was warm to the touch in front of the rad when running so I'll be replacing muffler anyway with the eliminator. AGCO wants $1400 for the muffler, rediculous. Still searching for the problem I took the water pump off. This is what I found.   So does anyone recognize this part. Brass and even has number stamped in it. It was inside the water pump, laying flat, just infront of the impellor. We're thinking it came from inside the rad. Broke loose somtime last fall while on the grain cart and then lodged in the pump. This pump may still be ok but we're putting a new one on since its out. $160 from Agco. This is the kinda stuff that drives me nuts. I really hope this is the end of this headache.

I'm considering pulling the water pump on my 8010… same heating / cooling issues as you mentioned! Thanks for the post. This is what a forum is all about! |

I was wondering if is was maybe left inside the tank when it was rodded at the radiator shop or was it origiallly a piece of the radiator. Dad said he is going to take the piece to the radiator shop just to see of they recognize it next time he's there. Unless someone here knows?

nice to FINALLY find the culprit !! I know stuff like that can drive you batty. Maybe 'google' the number on the tag ? I've found a LOT of interesting info doing that.

We did call our Agco parts guy, he is usually pretty good, he says its not anything to do with an AC number, but possibly from the radiator manufacture, he couldn't be sure. Leon B ------------- Uncle always said "Fill the back of the shovel and the front will take care of itself". |

| As I read that ,I come up with 0265065 which would make that part of a 7000 series PTO shield someone made a tool out of and left behind for you to eventually find. My bet is longer ago than when the rad was rodded. |

Actaully the first digit is a C, so it didn't mean anything to our parts guy. Leon ------------- Uncle always said "Fill the back of the shovel and the front will take care of itself". |

| Glad also that you found your problem, I was thinking that the oil cooler had a brass tag on it, but what you have there seems too big. Good Luck, Mike |

| Looks like it might be a baffle in the radiator, of some sort... |

70265065 is a shield and an Agco part # don't know if it fits an 8000 or not ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

Mack, the piece of brass was inside turned parallel to the shaft. It looked like a flap valve. I'm guessing the flow was half, I don't know. I'm not going to guarantee it's fixed but it sure looks promising. Leon ------------- Uncle always said "Fill the back of the shovel and the front will take care of itself". |

I sure hope that solves your problem. Whatever the outcome, it is good to get foreign items out of your cooling system anyway. You want to work some magic on my Mack truck now? It wants to run hot in funny ways like you were experiencing. I believe I will be pulling the water pump now just to satisfy my own curiosity! Thank you for sharing your findings. It might save some of us a lot of anguish. ------------- If it weren't for the last minute, I wouldn't get anything done! |

I had a modified F350 that tended to heat up. One day I took the fan belts off and found the water pump shaft spun freely and coasted like there was no impeller. I didn't take that pump apart to check the impeller but traded it in on a new pump and that solved the overheating problems. My guess is that the impeller cracked and didn't grip the shaft anymore. Couldn't see it from outside the pump on the 390 engine. Gerald J. |
