Low Coolant Light Warning
A plea for suggestions, if I may?
I have a 2000 Suburban, 5.3L engine. Two hundred and twenty thousand miles. Been a great vheicle.
The dang low coolant warning light comes on every so often and it is driving me nuts.
Sequence of recent events:
A while back, light comes on, check reservoir, add fluid, and go on about my business.
A few days later warning light reappears. Shucks. Add more coolant. Fluid is going somewhere.
Took it to a radiator shop. Replaced water pump after a radiator guy (local business) said he saw it leaking a bit. Also checked all hose clamp fittings for tightness, etc.
Light reappears again in a few days.
A week or so later, the Mrs. rear-ended another vehicle at low speed and had front-end damage. Radiator was replaced due to the accident damage. I think the coolant sensor is in side of the radiator but I may be wrong. My thought is the sensor should be good.
While at the repair shop / body shop, a GM mechanic there diagnosed bad head gaskets (of which I suspected). What else could it be (I am thinking)?
Had the gaskets replaced.
The Mrs. called this morning on the way to church... low coolant light returns..... She's mad and I'm going nuts.
Any suggestions please?
