Title: How can i check my motor temperature?
Post by: Yoni159 on May 23, 2020, 02:15:23 PM
How i can check my motor temperature if its not overheat can i check it with non contact digital laser thermometer? If yes so where i should aim the laser thermometer? The the engine block? Or engine case? Or the cylinder block?

To what will you compare any reading you take?
Or are you just curious about temps on various parts of your scooter?

There's probably no significance in the temperatures. You are only measuring the outside of the engine which is inaccurate as they do not represent the inside of the engine. Plus there is no airflow which will decrease them further.

Who cares as long as it runs.

What really matters for engine health is the oil temp. If the temp exceeds the oil rating it loses some lubricating ability which can cause additional friction, heat, and wear. If the bike is stock I wouldn't be concerned about the temp.

If you don't need a readout while driving I would look into dipsticks with a temp gauge built in. I have a carbed bike where the temp especially when modding is important and some people install an oil cooler depending on what all mods have been done to the engine.

Does your bike have a problem to cause you concern?

yes i was a leak from a weep hole in the water pump about a year ago but not real leak its was.few drops and i never fix it.. now its not leak anymore but its still the seal still need to be worn.. and i concerns about maybe its can cause a oberheat and i didnt know it

yes until you have engine failure in the middle of the road... Great answer

Maybe you want to know the coolant temperature? That's what the dash gauge is showing but without an actual number of degrees. Autos run around 180-190 degrees F.  I, too, would like to know the actual temp (of the coolant). Why doesn't the gauge at least have a red line or light to warn of overheating?

If it's already stopped leaking then there's nothing to worry about.

If you're worried about overheating, make sure your coolant is topped up in the reservoir (under the left footboard), very old coolant is changed for new coolant and your radiator fan is spinning (it cycles on/off). The only way you can tell your system is not overheating is by looking at the digital temp gauge with 3 bars.

The gage indication IS pretty broad but it is what it is. Better than a light that comes on when too late!

yes i flushed the whole system about 3 month's ago with fresh zerex green coolant and the radiator and the reservoir are top up

 And another question in need to do 40000km service and now i am on 41500 km can be done damage to the scooter if i delayed it in 1500km?
Title: Re: How can i check my motor temperature?

No. The service intervals are based on experience and judgement and to a certain extent are quite arbitrary. No harm is done by a 1500 km over. You can pick up the next regular interval or extend it by 1500 km if you wish. The main idea is to have some periodic system.

  on my 2016 Piaggio b v 350  the Temp. reads 190  ,. riding on the road,.  in stopped  traffic it turns the fan on and reads 210,.

If you're really concerned and want to monitor your temps, buy an aftermarket sensor and gauge such as below and mount it. I've actually thought about doing this myself, but then I realized I have no real need, I was just board and wanted to mod the bike.
