I have a SR and pieced together a heater hose setup when I first installed the motor. One of the hoses ripped so I decided to buy the kit that XAT sells. I installed the kit, filled up the coolant and for some reason after the car warms up, it starts to overheat, and there's steam and water dripping from the coolant hose lines going into the firewall. I've observed the hoses and they're on tight. Does anyone know what is wrong with it?

 

observed to make sure there tight?

tighten them up if u have not. happened to me b4 they get loose sometimes

 

oh alright. Thanks.

 

Teflon tape pipe thread sealer FTW. But loose heater hoses wont be a "cause" of overheating unless you are already way low on coolant. I don't know anything about the XAT kit, but some heater hose kits have 1-way check valves in them - which would keep coolant from circulating if installed backwards, and would cause overheating.

Check and see if you are getting heat in the car, to see if the heater core is getting hot engine coolant. After that, check the thermostat (simple but effective). -JinX

 

jack up the front of the car and rebleed the cooling system
