My ?Is their any difference in a Thermostat for the 257 linhai engine and the 244 honda clone engine?Will either thermostat work in ether engine.Thanks for any help ahead time.

Not sure, both engines (244cc and 257cc) are different. pm bobf he has the 244cc one.

OK, the water is much the same in both.

I looked them up in the Roketa parts book and sub assembly charts. To me the pictures look the same.

MC 54 250 03-03 temperature sensor at $15.00

MC 54B 250 03-14 temperature sensor at $15.00

The numbers look the same except for the last number which indicates the item number on that illustration page. First guess is they are the same.

Scroll well down the page to find MC 54 250 or MC 54B 250, then click on 'Sales parts and menu', now scroll down into the parts area you want, then click on that name. Following the enlarged view will be a parts list. We only get a numbered item list but never a complete part number for the items.

EDIT to add: If you have one in hand just take it to a auto parts store and see if they can match it.

Whoa there, Grasshopper -- "temperature sensor" and "thermostat" are two different animals. You wanna be sure which you're talking about and which you're ordering.

You may be correct. The only thing I found on the parts list was the thing called temperature sensor. I never found one called thermostat. So I (ass u me) assumed that what I said was correct. Now I say, so what if wrong, the solution is exactly the same. Take out what you want fixed or replaced, take it to an auto store and ask them to replace it.

As I understand it the temperature sensor is an electrical gizmo that turns on the fan at a certain temperature, while a thermostat is a mechanical gizmo (bimetal spring concept) somewhere in the coolant flow circuit that opens at a certain temperature and allows coolant to circulate. I am only ass u me ing that scooters even HAVE a thermostat, have certainly never seen mine on either scoot. Be that as it may, I think thermostats are pretty generic, so pulling the old one and taking it to AutoZone or a cycle shop should work. Best I can recollect from my auto tinkering days, aside from physical size, which has to be exactly right, thermostats come in various temperature ranges, i.e., they open/close at higher or lower coolant temperatures. So if for some reason you want your engine to run cooler you would opt for a lower-temp thermostat that allows coolant to start circulating sooner. As to temperature sensor, I dunno if they are generic enough that places like AutoZone would have a replacement, but odds are a cycle shop would.

Casa Grande, eh? Maybe if I can figure out how without doing I-10 I'll scooter up some time and say hi. We can compare notes about our aching backs.

I mess the first one up, but below is where the thermostat is.

Yep and right there is the TEMP SENSOR.

Hope I never need to get at either of those -- looks like every shred of plastic has to come off!
