Coolant smell???

**dieselkane** · #1 (**permalink**) 12-28-2009, 06:01 PM

I have recently started smelling coolant pretty strongly. Definitely more so than usual. The level of fluid doesn't seem to change, and I haven't added any in a LONG time. But I am smelling it fairly strong now.

There is pressure in the cooling system, but it doesn't seem excessive. I am lost... anyone

If you smell it, start looking. Check the radiator and hoses, sometimes the o-rings leak. Have you had any work done recently? (not just coolant related work)

No work done recently. No engine work done ever actually.

Check o ring at radiator hose middle front bottom. I took mine in, $244.00 to fix, not under warranty. I have had white exhaust rarely, the shudder, the billowing exhaust and noted I lose about 1/2 gallon antifreeze each time. The antifreeze odor was present. Good luck...

Take the truck out and get it up to temp and flog her real good. Then immediately pull over and open the cap just enough to relieve the pressure built up.

Post up how many seconds it hisses for. Anything more than 1-2 seconds and you may have the same problems as me.

I like to check the pressure when I get home, and when I get out of the truck I usually smell coolant. When I loosen the cap, it takes a bit to relieve pressure, and there are also bubbles I can see coming up when the engine is running. But I don't think the bubbles are a problem. I have a coolant combustion gas tester, I will test it today to see if there is C02 present. I REALLY HOPE NOT

I thought my cap was loose when I first started smelling it, but that isn't the problem.
