hello,


i am from Belgium and i have a camaro 68.


i have a prob with the lamp in the dash thats indicate the temperature( dummi lamp)
when the engine is cold and i turn it on afther 5-10 min the dummi lamp go s on. the engine temp is 200-210 farenheit and it stays on that. so evrything normal. its a new radiator new water pump and a new sensor. its strange that the dummi light of the temp go s on after 10min. when i take the cable of the sensor the light goes off. when i put the cable on a negative(engine) the light goes on. is it not an electric prob?


i hope someone can help me. it turns me crasy


thanks and greetz from Belgium.

 

i would suspect the sensor. what engine? stock should be 170-190 operating temp, 200 in hot weather

 

Replace the sensor...

 

Years ago I had a stock 69, and put on aftermarket gauges. Normal operating temperature on my 307 was 180, it never went hotter. I'm not sure what the temperature threshold is for the idiot light sensor, so I'd be more curious as to why your engine is running too hot. My current 69 might get up to 200 when screaming down the highway at 4k rpm's.

 

it is 396v8 big block. i put now a sensor from a potiac trans am 73 455 superduty 7.2v8 when the dummi light goes on i have 210 farenheit and it stays on that temp,when the engine just turn.

 

You should be using a sensor made for your car, doesn't matter what engine you have in it.
Also make sure you're using an idiot light sensor, not one for a gauge. They work differently and aren't compatible.

 

thanks i will try that, thanks alot for the info. i hope it will work.

Since you have a BBC, aka, 396 CID, I suggest checking the following:
1. As said earlier, correct sensor, thermal switch for light - use Standard Motor Products P/N TS-11.
2. Use a 180°F thermostat
3. Use a fan shroud, and if no A/C, w/pump pulley and crank pulley are the same diameter; if A/C equipped, crank pulley will be larger diameter making w/pump spin faster and fan pull more air across radiator/condensor.
4. By design, BBC's with A/C, had a large foam insulator or single flap sealing strip across radiator support preventing air recycle across radiator from fan. If yours is not A/C equipped, maight try this to help cool.

 

hello,


i gonna start with the right temp sending unit for dummi lights


thank you .


many greetz from belguim.
