Hi, my ke70 currently has no thermostat so it runs cold. I'm looking to put one in but I'm pretty lost is this a top thermostat: http://www.ebay.com.au/itm/TOYOTA-COROLLA-KE70-1-3L-8v-CARB-1981-1985-Stant-Superstat-Thermostat-/280833544296?pt=AU_Car_Parts_Accessories&hash=item4162fbd068#ht_4326wt_914

 

Also does it just go in the top radiator hose near outlet from the head somewhere?

hey mate,

 

best bet to go to repco and grab one, might even be cheaper than that. then you can take it back if it isnt right.

 

that ebay add does look right though. but yeah i don't recall them being 30bucks from repco. maybe $18 or $19.

 

here is a photo of where it is:

 

 

the best photo i could find on google images.

 

but the head is running to the right.

 

that thing that is corroded is held on by 2 bolts (you can see one, one is just out o fhte photo)

 

the thermostat is located under this.

 

make sure you get a new gasket too, and give both gasketing surfaces a VERY good clean.

 

i have found it best to get to both surfaces with a flat file, so you can make the surfaces nice and flat. and clean off all the scale while your at it.

Awesome, thanks for the detailed reply.

Pop in to the local auto shop and ask for a Tridon thermostat, part number - TT240-180 and they should just have to pull it off the shelf.

About $18 from Supercheap.

We run the TT240-160, the engine runs a little cooler and we make a few extra HP on the dyno.

why do you make more power with the engine runnign cooler? heat = power....

Probably keeps the engine from getting too hot

One reason would be cold air going in is denser. That's why cars run better on cold nights.

 

A motor is designed to run between about 75deg and 90deg. That suits the metals and the lubrication, so the system is designed to get up to those temperatures as soon as possible then level off and stay there no matter what load you put it under. That's why you need a thermostat and warm air intakes when you start driving, then cold air when the motor is up to temperature.
