Cold mornings?

**pewter99** · 12-12-2003 12:02 PM

It seems that when I start my truck and take off in the cold mornings, I hear water running or spashing around the passenger side firewall. There is no leeks in the cab or any where. Anybody have this problem or know what is causing it?

Can't help you there, mine makes all kinds of noise, hahah

good luck fixing it, hope it works out,

coolant overflow maybe? when it heats up the water/coolant basically expands into the "catch can" or collant overflow.

could be that. :shrug:

More than likely you are hearing water/coolant circulate through the heater core.

That does make sense, thanks.

That is what I was going to suggest.
