Gravely 260 Getting hot.

I have a Gravely 260, with a Kawasaki 27 HP water cooled engine. Ever since I have had it (not new) the temp light comes on after about 15 min of mowing. I have replaced the temp sender but still happens. There is no thermostat in it (previous owner removed it) It does not boil over. I checked the radiator with a inferred thermometer and it reads about 180 and the block shows about 240-250. Could the water pump be bad? I don't think the radiator is plugged. Any suggestions?

I have learned that everyone with a radiator on their mower should have a radiator clean out tool…they are never clean until you do so. Do that first and foremost and properly clean it. If any of the fins are bent down from power washer, try to bend them all back so it can have proper air flow. This is extremely important with lc motors...

I would back flush and fill it for one, anything with a ton of hours that has never seen a proper back flush is likely to have corrosion and dirt in the water system getting in the way of progress. A nice, proper flush of the system, then re-fill with a fresh 50-50 mix.

And I would put a thermostat in it.

For the correct answer when it comes to the water/antifreeze mix:

Read the instructions on the container...it's there in black and white. That way you don't get bad info.

Ethylene Glycol and water always mix the same way.
