level sensor in coolant reservior no floaty

[mrg]

Ever since I got my supra the coolant level (bird cage) light has been on. Today I finally pulled out the reservior and cleaned the damn thing. I can actually see thru it now! Anyway, I tested the level sensor with an ohmmeter and it reads normal. (open circuit when up, ~4-5 ohms when down). The problem is, even after cleaning - water does not make it float.
Anyone ever have this problem?

hmm, maybe a wiring issue?

 

[Afunk]

they don't float

jonathan1: NOT a wiring issue - I can make the light go on and off by moving the ring up and down

if the ring doesn't float then how does the sensor work?

Personally I just disconnected the sensor. It's of no use to me as I check my fluids at least once a week. Disconnected it will not throw the light.

True.
I certainly considered that - but I want everything to work. Maybe I could glue a foam ring to it?

If it's an up and down thing I would guess it should float. Maybe there is some foam or somthing missing from yours.. The TSRM does not go into details..

More backyard engineering for my toyota... : )

Try another reservoir? The 86.5-92 N/A and turbo should all be identical in fitment, harness and specs.

float is full of water! drain it, clean it, coat it in a thick layer of epoxy

Or get a new bird

Thank you!
But here is what really bugging me - Is the sensor designed to be removed easily? If I try and pull it out will I break it?

hahhahaahhahhaahhahhahaha removed easily....... ROFL hahhahahahhahahahahahahhaha

You know its a Toyota Supra yeah?

LOL ya can't even open the lid easily!

 

[mrg]

Update:
Pulled the coolant level sensor out of the tank today.
The float was heavily covered in dried glycol. After scraping it off, the float became lighter - but not enough to float. The core seems to be made of a solid, porous iron inpregnated substance so i couldn't drain it.

Sick of the whole thing - I cut up some packing foam and epoxy'd it to the top of float ring. Let it dry and trimmed it up. Baby works like a charm.
