CAT 951c getting hot

[Coaldust]

Dagnabbit. This thread is going sideways. We need a serial number. This ol’e 951C is hot and bothered and it needs fixed, ASAP.

Or, before long, we’ll be talking about blown cylinder head gaskets and cracked pre-cup chambers and other mayhem.

Aftermarket, ah?
Like from Walmart or a quality unit from ISSPRO or Murphy?

I would not trust the accuracy of the replacement gauge until verified. Been there & done that. Learned the hard way.

I got this guage from Autozone. Had the same one on a skid steer that I used to have.

Have you cleaned engine oil cooler tubes that coolant flows thru it to keep oil temp in check. Will be over top of spin on engine oil filter.

I have not but they removed the entire engine when they did the rebuild.

Ok here is the S/N 69H4866. Yes thanks for all the help!! Just spent $6700 on rebuild and dont want it to blow something else

Roger that. Let’s take a couple measurements today, (after you install the regulator).

Beg, borrow or steal a infrared thermometer.

Next, get her warmed up. Work her until the regulator opens up. You can tell, because the top radiator hose will get hot when the water starts going to the radiator.

First, record the temp reading of the dash gauge. Go to the engine and use the infrared thermometer to take a reading at the gauge sending unit.

Next, Measure the temp at the regulator housing and then at the lower radiator hose where it connects to the water pump.

Watch the fan! Watch the belts! Be careful. And report back.

Ok Will do. I am waiting on CAT to get back to me on the regulator. As far as the fan and belts go, belts and fan are new, However the fan is blowing out instead of sucking in, is that correct?

I think that fan is reversible. Air flow direction may not make a difference in our troubleshooting, at this point of the process. Good to note.

If it is in fact a reversible fan make real sure all the blades are locked in and pushing or pulling the same way. Had a D333 or maybe a 3306 in a 966C loader that was overheating and found the problem was someone missed one blade while reversing them!

Almost every front engine track loader I have seen had a pusher fan, after you run one awhile you will see why.
