Kw w900l cat c15 overheating

Do you know if it's a 3 or 4 row radiator? I don't know about KW's, but Pete's usually run a 3 row radiator up to 475 HP, higher HP runs a 4 row. If you had a factory uprate, 550 is still the same engine rating family, but you may not have a good enough radiator for 550 HP. Typically, if the radiator was replaced, replacements are all 4 row unless you bought an OEM one from the VIN.

If you radiator is OK, thermostats are a possibility, I'd use a temp gun on the outlet and you will be able to see where they open. They may be opening fully to equalize the temps in and out, but they may be opening late.

Also verify your temp with a temp gun on the T-stat housing, 200 is not bad, If I remember right, they are 195* T-stats in Acerts. It's possible that you have a sensor issue showing higher a higher temp that it really is. On you truck, you only have the 1 sensor that gives the same signal for the gauge that the ECM reads. It's always good to verify that it's giving a correct reading. The sensor is on the front of the T-stat housing behind the accessory bracket and a pain in the butt to get at on an Acert.

 

+You may have to swing the A/C con. out of the way to get to your air to air cooler to ck. for dirt covering front of air cooler then pul air cooler to see how much dirt is covering ft. side of rad. if all is clean pulling rad. to have it cleaned on inside at a rad. shop or replaced, some replacement rad, are not made to last as long as the ones that came on them new?

 

Is 225 degrees overheating the engine?

 

Not quite. It getting up there where theres an issue or you would question why it's that warm. Not alarming and in panic mode yet. Engine fan on is 217*F. Are we talking coolant temp? Oil temp may be considered normal considering operating conditions.

It is unlikely that 225 would cause permanent damage or a failure to any engine.

 

Anyone check your oil cooler? If it's not doing it's job, your coolant temps will rise to some degree. Just a thought.

 

Not likely cause water boils at 220 am some change I think. Hard to cause damage when coolant is still flowing unless it’s so god awful hot like Evans coolant
