This should include both the visible and internal aspects of the exhaust piping. Loved it so much bought second one in 2007 and had ran hot since day one. we have a commercial exmark zero turn mower that turns off when it gets to hot and i cant afford to take it to repair shop. Each diesel engine is different but ideally the coolant boiling temperature will increase under pressure. 22328HD—Serial No. It is important the fan shroud and the baffling be the correct size and positioned correctly. in. B.) If the outflow of air measured is less than of the minimum rated allowable air flow for the engine than it is advised to inspect the air cleaner. I’ve owned two Kubota diesel zero turns, and bought both new. If no leaks are visible it is advisable to pressure check the line with forced air. Toll Free: 844-340-4114 The loose hose clamp is something a lot of mechanics often overlook but this simple issue can allow air into the cooling system which causes a reduction in the cooling capacity of the coolant/anti-freeze mixture. B.) • Overheating can cause the camshaft to swell and then break. It is advised to drain the current cooling system and then flush out any leftover coolant. • Overheating can cause damage to the bearings and crankshaft. Minimum antifreeze levels for Caterpillar engines must consist of at least 30% ethylene glycol based antifreeze. Whenever you need service, genuine Toro parts, or additional information, contact an Authorized Service Distributor or Toro Customer Service and have the model and serial numbers of your product ready. Any sort of dirt between the fins can restrict air flow throughout the radiator core. See actions taken by the people who manage and post content.

If the sending unit is malfunctioning it can give incorrect or missing data to the temperature gauge. A.) Much like hoses and clamps a restriction in the air inlet system can cause overheating to occur in the cylinders. Something simple as a cap not closed can overheat and engine and ruin it. The thermostat was changed and system flushed last year, the coolant is full, I even added "Ice" by Royal Purple to try to get the temp down. The Stage V engine uses passive DPF regeneration during . The higher an engine operates at altitude the lower the capacity of the cooling system on the overall engine. Detroit Diesel had been building only 2-Stroke Cycle engines like the venerable 6-71 since General Motors created the division in 1938, However, by the late 1970’s with the raising cost of diesel fuel and the inefficiencies inherent in their 2-Stroke Cycle engines which caused them to consume more diesel fuel than their competitors’ modern 4-Stroke Cycle engines, DDC realized that for … A.)

OEM trademarks, such as Cummins®, Caterpillar®, Detroit Diesel®, Mack®, John Deere®, Komatsu®, Waukesha®, are trademarks of the respective OEM. Follow the engine operations manual to the letter. It is important to not push an engine too hard under load for an extended period of time however job site conditions sometimes dictate extensive wear on the equipment. Overheating can occur when two different coolant mixtures reach different boiling points. Some electronic diesel engines will automatically switch to air-cooled at reduced power if there is a loss of coolant. Damaged hoses usually can be seen visually if there are any leaks in the line. Hi I,m LOZA Have a D1105E has been brilliant,it powers a Toro greens master, althought it is getting on I have religiously kept it well maintained like all my mach;over heating started slowly now 10 minites and she stops,checked everything,inc water pump-rad and a new fan,next a full flush out,I lose no coolant Toro zero-turn radius mowers can cut mowing time because they are easy to maneuver around obstacles.

The Toro Commercial 72-inch 7000 Series zero turn riding mower features a 898cc Kubota Diesel engine, durable construction and enhanced comfort. An improperly sized radiator will cause the engine to run at a higher than normal temperature. Adjust the water pump belt as needed. Hoses without any major leaks can soften over time and be susceptible to fraying. If the water pump is only working at half capacity it will result in low coolant flow and thus overheating of the diesel engine. Temperature diagnostic systems might simply need to be re-calibrated. Normal operating temperature of a Caterpillar C7 for example is 180-200 F °. Take notice that all OEM manufacturer’s brand names, trademarks, symbols and/or product descriptions are for internal engine/part model identification only. The radiator is prone to getting clogged with dirt and debris. The soft areas of the hose can become kinked or crushed during operation and restrict coolant flow. It protects the stems, bearings, etc… The coolant conditioner stabilizes the cooling system and is very important. C.) Another remote possibly of overheating from the exhaust system is that somehow hot exhaust gases are being drawn back into the cooling air inlet.

If the air cleaner is beyond cleaning replace with a new OEM spec engine air cleaner to prevent engine overheating. • Exhaust valves will expand causing damage to the valve guide. You may contact Toro directly at www.Toro.com for product safety and operation training materials, accessory information, help finding a dealer, or to register your product. C.) The fan shroud is the housing that hold the fan blades in place. Matching the quality of the coolant to what is already in the engine is important. When air gets into the cooling system it will cause a reduction of coolant flow due to the presence of air bubbles. If the air flow is less than the minimum amount allowed by the OEM it means there is a blockage somewhere higher in the exhaust system. Overheating can cause a number of problems to the engine. Consequently if the wire from the sending unit to the gauge frays or shorts out it can cause the temperature gauge to not work correctly. Installed some missing rollers and took her out to try.

The consistency of the coolant should have the following properties: • Color that is similar to the old coolant used If the new coolant does not roughly match the coolant in the engine do not add the new coolant and “wing it”. Not even the much-praised zero turn mowers. The baffles keep the temperature of the radiator down therefore any missing or damaged baffles will cause excessive heating of the air through the radiator. For example the radiator filler cap rated at 15 PSI will generally increase the boiling point of the coolant to 265 F ° with a 50/50 mixture of antifreeze and water. Lack of the proper air flow can cause the coolant not to cool to the proper temperature differential. #2B Denver, Colorado 80229 A blockage from the air coming out of the engine can cause excess overheating in the cylinders. A blockage of the shunt line from the radiator top tank to the engine water pump inlet will cause a reduction in the water pump efficiency. Make sure there is not a blockage in the engine compartment and that all of the associated radiator exhaust parts are not damaged.
