i have a b18b now and i noticed that the block doesnt have that plug like the picture above on there wanted to know where i can connect the wire's that go to that

 

Help

 

 

that plug is for your cooling fans. i think its a cooling fan temp switch. but on the b18b its relocated next to the thermostat housing.

i hooked up a plug to that sensor by the thermostat housing like ur talking about and my temp goes to half warm when the car hasnt even been started in like 2 day's i just turn the key and it's on half warm i tryed switching the wires and nothing ****'s got me confused, i've had different motor's in the car and never had this problem... thanks for you reply

 

where exactly is it located? i know when i had a b18a in my rex there was a 2 prong sensor to the side of the filter and one more on the top of it.

 

Yeah being i cant see your picture on the back of the B18A1 there is a 2 prong thing for you temp and thats for your cooling fan i also have found a B18A1 but it was a 92 and the temp sensor was on the thermostat housing and on the b18b1 the temp is on the thermostat housing so im thinking 90-91 engine on the back where the oil filter is is the 2 prong thing for the fan and... but if your starting the car its automatically already at half way i dont know what to tell you on that... sounds like you have postive battery going straight too it or something... have you ran the car until the fan kicks on... it will take a while for it to kick on but if it does start to over heat your anti freeze will kick into your resovor box then thats when you shut the car off and if the fan didnt kick on i'd say get your own fan to it so it can cool down..

i drove the car today around the block and left it on for a lil longer & fan's didnt turn on & it didnt over heat temp stayed the same.. Thank for your reply

 

like everyone said, the picture is the thermo switch for the radiator fan. That sensor has nothing to do with the guage however.

The sensor that is bad that is most likely causing your guage to flip out is a coolant teperature sending unit, which should be on the distributor side of the engine. it should be a single wire, and you should measure the resistance from the post on the plug to the engine block. I dont know what the resistance values are for the b18 sensor, so you will have to look it up, but figure those out and you will most likely have your answer.

 

i dont know... the relay could be bad if the fan isnt kicking on...
