Sensor light looks like carousel?

scruffboy · 10-20-2005, 11:54 AM

On the left side of my dash in my 89 Supra, there is a sensor light that looks like a damn merry-go-round. I've only seen it light up once, when I first bought the car. What the heck is this, and what is it suppose to represent? Are the Japanese messin with our heads? I know I wasn't seein things, so what gives?

Sincerely,

James

what color is the light....orange? if so then the radiator reservoir is low on coolant

Ok, my coolant is topped off, but there is none in the plastic reservoir tank. Is that good or bad. I thought the reservoir was for overflow. The car never overheats.

Thanks

The light works by a sensor in the plastic bottle. It should be kept at 1/2 full. These cars will, on occasion, send coolant to the bottle when hot, then suck it back into engine when it cools down.

OK, so I go the radiator topped off, and I don't leak coolant. But you say I should fill the plastic res to half full? That's easy enough, but I thought the plastic reservoir was only for overflows. I'll take your advice, I don't see how it can hurt.

Thanks,

James
