Our sons 1989 Chevy truck overheating
There's coolant in the container but when we open the radiator cap and look in yes empty
every time after we fill it up and use the truck. The temp gauge will show its hot and car
will show check temp gauges and start running rough. When we put our ear up to the
hose you can hear a gurgling noise and hose is stiff.
Can you see it leaking from the water pump or hoses or the heater core or radiator?
We just purchase the truck for him 3 months ago. We have put in a rebuilt transmission but now it's overheating
We can not see any leaks at all
Is there oil or foamy substance in the coolant reservoir?
It started overheating the day the transmission went bad and my sons grandfather had opened the radiator cap when it was hot and it spilled everywhere. Then he added water to it for our son to get home. Do you think this is the issue.
It soapy looking one time but now it's not Thank you for helping us
At jiffy lube they said it was soapy when they opened the radiator cap
Sounds like it might be a blown head gaskit
We just went out this morning and looked at the resovour and its empty
Make sure it's not leaking into the trans cooler, could have been why the trans went out. Check the trans fluid and make sure it isn't pepto bismal pink
On a simple note, have you changed the thermostat?
If Grandpa put a large quantity of cold water in the radiator, when the engine was overheated, without the engine running then, once the radiator was full, started the engine the sudden temp change may have cracked the block or head. HTH. -Jim
