February 3rd, 2004 09:12 AM #11Lahat ng liquid-cooled engines ay may thermostat. Almost 100% of the time nasa upper hose naka connect yung thermostat. Subaybayan mo lang yung hose papunta sa engine side. Yung flange na saan naka connect yung hose ay syang housing ng thermostat. Tanggalin mo lang ang flange na yun (held down by 2 or 3 bolts). Expect about 1/4 of the engine coolant to escape when you remove the hose.

Keep the thermostat. Other things that needs thermostat: aircon,
ref, flat iron, oven, range, freezer...it's there for a purpose.

February 3rd, 2004 03:13 PM #13hey guys! i read all the threads and I think dapat nga yata talaga andun yung thermostat. I had that problem with my honda vti... sabi nung mekaniko, wala na daw yung thermostat so ang tagal bago magbukas ng fan... sobrang init na talaga ng radiator before it turns on (pero di ba dapat hindi na sya mag-on kasi nga wala yung thermostat?). now I have to buy a new one... meron kaya nyan sa mga surplus shops dyan sa evanghelista? or if new, magkano kaya yun sa casa... (tragis gastos na naman...)

Actually, the radiator fan is switched on and off from the E.C.T. sending unit via a relay. You can remove the thermostat and the fan is still going to turn on and off depending on the temperature of the engine coolant.

if this is the case... what is the function of the thermostat? isnt this the one which turns on the fan? thanks!
on the other hand, yung mga hindi belt-driven fans ay ino-off/on din ng isa pang thermostat. yung iba wina-wire directly yung motor ng fan, bypassing this thermostat/switch para palaging naka-on.

February 3rd, 2004 05:21 PM #17ebbfols,
thank you! so there are two thermostats operating... one for the control of the coolant flow and one for the fan... I asked coz my car keeps overheating! and just a 78km run from laguna to makati. I had it checked before and the mechanic said the thermostat is missing... But I assume this one is the one controlling the flow coz he removed the tube connecting the engine and poked it with his screw driver... having found that the screw driver was unobstructed by his methodical poking procedures, he concluded... it was removed. now im afraid i have to replace both! =(
Do you know where I could have this fixed aside from the CASA?

February 3rd, 2004 05:59 PM #18Hello. Istarted the thread and was talking about the thermostat usually located in a water outlet on top of the engine by the upper hose.
The other one is the THERMOFAN switch usually attached to the radiator and is used to turn the fan on and off on FWD cars.
Madaming nagoverheat dahil dyan sa thermofan switch and is often overlooked as a cause of overheating. MAganda ginawa ng Mazda yata? Pag nasira ang switch, always on ang fan(failsafe) binaliktad lang nila ang wiring, unlike other manufacturers always off pag nasira anf switch. Makes you wonder why they didn't copy Mazda on this simple solution...Pride?

Actually, the Corolla has the same failsafe feature, and I think most if not all cars are the same. Is there a particular model you noticed does not have this feature? I still dont understand why the thermostat should not handle both duties of controlling coolant flow and fan operation. The only reason I can think of is that the fan switch monitors the coolant in the radiator while the thermostat monitors the coolant in the engine. This way the fan does not turn on until the coolant from the engine enters the radiator. But it still sounds a bit redundant to me.

February 4th, 2004 10:51 AM #20thermostat and thermoswitch are 2 different things.
it's best to have both installed and working properly to ensure that the car doesn't overheat
Kwento ng katrabaho ko, meron daw sya officemate dati na Italiano na tinanong daw bakit...
