Where did my coolant go?
« on: 28 October 2005, 16:22 »
Drove to work this morning, nothing unusual at all happened.

Left my car for 5 or so hours, got in it at lunch time and drove away, coolant warning light was flashing, checked the bottle, it seemed empty, chucked a pint of water in it, drove about 1 mile, parked and left it for another few hours, checked the coolant and the full pint was still there.

I put another pint in and drove home, car behaved perfectly normally.

I don't check the coolant regularly but it was serviced about less than 2 weeks ago and the coolant was replaced so it should've been full.

Any ideas?

I checked the dipstick and the oil filler cap and the oil looked fine.

Get a blue coolant header tank cap from GSF. Might stop some steam loss ?

... it's turned into a fashion show for poofters.

Ive got this problem. Goes down about half a pint. Gonna try the blue cap mod 2moro morning

you can get a dye that you put in your coolant which makes it easy to pin point leaks.

common spots for leaks are the 2 flanges on the block, the one on the front with the temp senders in and the one on the right hand side that goes to the heater matrix.

you might wanna check around your water pump, mine was leaking sometimes but then it would seal itself up again... didnt bother fixing it.

You might also find the thermostat housing has not been fitted correctly which causes it to drop the coolant when the engine warms up but if not a long distance Thermostat doesn't open and no water leak.

Mine was coming out through the coolant expansion header tank seem, when it had been running for some time.

Changed tank and was fine for a while, then leaking from radiator a few months later. Radiator then needed replacing .
