so when I fire up the truck(91 22re) I get that sucking/slooshing sound of coolant passing through something....is this a shotty heater core? My brain is still in work mode...basically off, thanks for the help[cheers][36]

depends, is there coolant leaking onto your floor, or the smell of coolant when you turn your fan on?

I've heard it too sometimes on my 22re, and the heater core is new. I have also heard it on a friend of mines Toyota, a later model 3.4L V6. Not sure why, but Ive heard it over many years. I haven't worried about it.

oh I forgot I made this post haha. Yeah I noticed my buddies 4runner does it as well. no smell or mist of coolant though. and it only lasts for a bit then goes away. Meh, I'll worry about it after I take care of my balljoints. thanks guys.

my 83 used to do it now it doesn't anymore. was only during the winter months. no idea what it was, never had any loss of coolant. was always after startup and running for 20 seconds i'd hear a swoosh and that was it
