Brown radiator fluid??? I have a '89 Chevy Suburban that started leaking fluid. ?

get the complete cooling system flushed out real good and put in a new thermostat and refill system with a 50/50 mix of antifreeze and water.

dats nasty lol ok if ur fluid r brown n u already got all the hoses changed u should also change the thermostat and water pum n radiator n put new fluid into it it would make a way better change u can feel when u drive dont ad radiator cleaner or **** like that ill pop ur hoses because it eats the rubber in high heat trust me i kno i went threw all the hoses 1 by 1 lol

but seing how its a 89 suburban it up to u man i kno time r hard but if u still think it reliable then fix it if not try craiglist it n sell it

Sounds like the hoses were changed for a reason,got overheated

maybe ? when an engine gets overheated even slightly,all the

natural rust in the block and heads comes loose and turns the

coolant like this.

I would take off the top and bottom hose,take out the thermostat

and rinse out both the block and radiator very well,then install

new thermostat and put hoses back,refill and see if you have

anymore problems ,you may not have any,try it and see.

Find out where it's leaking from and you'll have the answer. It can leak from a hole in the radiator, a cracked or loose hose, water pump gaskets or a worn water pump bearings, heater hoses, heater core, thermostat housing, etc. Stop-leak is the worst idea, and usually causes more problems than it fixes by clogging things up. Its better to just find out where the leak is and have it repaired.

well brown mostly rust but sorry if its brown and soupy most like head gasket dont have to show but any one sign and coolant and oil mix in radiator is one sign you try try flushing the radiator by draining what you have and then remove bottom hose open cap stick water hose in crank motor adjust water flow so most of it goes in radiator but dont think it wil help

New fluid starts out orange, old oxidized fluid can turn brown, most likely need to change fluid and repair slight leaks, when oil and coolant mix, usually turns a thick milkish color. Be careful if you use a chemical flush to change fluid, can uncover more leaks, I usually just drain old fluid, rinse with water, then add new dexcool

Just had this happen to me last week -- check the water pump to see if its working -- for your sake I hope it is as it cost me $400 to replace the pump and labor.

its your head gasket..... no doubt.
