Oliver 60 heating up

[Treeman22]

I have an Oliver 60 I got running within the last couple years. It runs great! I'm proud of how good it runs considering I'm not necessarily a mechanic.

Anyway, it starts right up runs great, but it seems to be heating up after it runs awhile. Antifreeze will run out of the overflow and the engine block will get hot to the point where I can only leave my hand on it for a few seconds at a time. Also my water temperature gauge never reads more than cold.

Another thing to note, this tractor has no thermostat in it. Should if have one?

Is anything I explained normal for this tractor?

I love driving and running the tractor and I don't want to ruin it due to overheating.

Thank you for your help!

Is this the same tractor with the recored radiator and new water pump? Why is there no thermostat? It should have a thermostat otherwise it will overheat. Has the temp gauge ever worked?

Yes it has a recored Radiator and new water pump. Also the temp gauge is new but I have never seen the dial move on it.

It didn't have a thermostat when I got it and I wasn't sure if it was supposed to have one or not. Would you have ideas on where I could order one?

Thanks

The part number is J525. I'd check with the usual places, Korves, Agpartsfirst, Ricks ag parts, Maibach, etc.

Thank you! I will look into this.

Maybe this question sounds silly but, is it possible that I need to run a power wire to the temperature gauge? Maybe that's why it's not working? Right now I have no power hooked to it.

It may have the same problem my S88 had. The block was full of rust etc. When I opened the block drain it only dripped coolant till I took a piece of wire and started poke around in the drain plug hole. Then it started to come out but so did chunks of rust. So I drained the whole cooling system and fill it with vinegar and ran it till it got hot and shut it down and let it cool. I drained that vinegar out and refilled with vinegar and ran it till hot. I let it cool and then drained it and rigged up a fitting so I could back flush the system by way of the block drain with a garden hose. Temp gauge on it now only get up to around 200 if that hot

Thank you. I have not opened the block drain. I will do that and flush it out very good. I appreciate the feedback!

Maybe you have one of those cheap made in India temp gauges..... I've had a few that didn't work right out of the box.
Mechanical (capillary tube) or electrical?
Before you spend any more money, that's where I would start. Get a good mechanical unit, before installing, poke around inside the block where the sender goes to make sure it's not plugged with crude, refill with water for further testing. Let us know what you find.

Update, my brother came to the house and we tested the water pump. Took the top radiator hose off and cranked the engine over. Lots of water pumped out. So the water pump works.

After that I drained the entire coolant system out and removed the block drain plug. I found quite a bit of rusty chunky junk and other dirt packed in there. I dug that out and flushed the system with a garden hose very well. I flushed from block drain until water came out the radiator and flushed from Radiator back to block drain. I did this several times until the water ran completely clear, then I flushed both directions several more times.

I also took out the temp gauge and made sure that was cleaned out. I tested the gauge by heating up water on the stove to 200 degrees. Dumped the water into a can and took it out and put the temp gauge sending unit into the water. My temp gauge needle moved up as it should with hot water. So the temp gauge works.

I will put vinegar in and run the engine until it is hot let it cool down and flush the cooling system both directions again very well. Then I will put fresh antifreeze in.

After this is complete I should have my issues resolved. Thank you to all who posted I appreciate the advice!

I suggest before you add antifreeze you work the tractor (harder the better) with just water. The rust chips may have gotten to the radiator and slowed the flow which will lead to heating. I wonder how I know that?

Thank you I will do this! I plan to run some vinegar through it as well.

Good luck with your project. Keep up the info. Good to share all our knowledge. Helping everyone here, is what this forum is, great job everyone. GG

You did get a thermostat yes?

 

[zanny1]

Be sure to flush the radiator backwards and forwards. I had a JD years ago that had crud in the bottom of the radiator tank that would clog the radiator when operating. You's be surprised what got poured in there over the years!

 

[Treeman22]

I have it ordered. I will put it in after all of the flushing and cleaning is complete. Thank you for asking.

I filled tractor with water and ran until hot, opened the drains and flushed both directions several times. I filled with water again and ran it for about an hour and drove it around. The temp gauge never budged off of the lower end of the cold. It didn't seem to overheat. Which is good. I was able to hold my hand on the side of the block for at least ten seconds at a time. I was able to do the same on the thermostat housing and the engine didn't boil over or anything.

I boiled water in a can and out the temp sensor in the boiling water. The temp needle only went up to the mid way point on the work range. I wonder if the gauge is not accurate? Is there any way to remedy an inaccurate temp gauge?

It seems the water in the engine would have to be basically boiling before the needle on the gauge will ever move. Maybe that's normal?

All to common now days to get a new part and it be bad right out of the box. Good chance that is your problem and probably made in the land of almost right

What kind of gauge did you get? Universal? Or original type cold/work/hot gauge?

The gauge has the the yellow background and reads cold work hot the colors on that are blue green and red. I believe it's the original type. But it was new when I put it on
