1997 CHEVYS10 PICKUP what can cause antifreeze to leak underneath truck ?
check oil first. If it looks like a milk shake, its most likely head gaskets. (worst case besides a cracked head/block)could be many things. Check upper & lower radiator hose connections. (upper to water neck...lower to water pump)Check the heater hoses on the passenger side going from intake & water pump into the firewall. (should be a 3/8" size hose)Those are a more common leak on the GM vehicles)if you hear a knocking or fast tapping noise, it could be the bearing in the water pump, and you could be leaking from the water pump flange at the front of your motor. Hope this helps.If you find the problem and need advice, let me know. eric
Replace thermostat
Fallow your Top Radiator Host toward the engine, The thermostatshould be at the end of that hose. Be sure you replace the new onejust like you took the old one out !!!
