I have the same engine in my Supra. For the first few minutes, it does blow some somke until the engine gets warm. Maybe I have a problem, too, but I did a tune-up in Feb or March and had no unusual symptoms on the plugs of water in the cylinders.
He should be. That's what's spec'd for this engine.
Bypass hose? Is that the hose to the bottle?
no, it's off the block to the left of the water pump and runs to the mount where the thermostat is. it's a short, fat, curved hose 6-10" long. hard to see but look on the left side of the motor front behind the water pump on the block. easy to overlook and does EXACTLY your problem. you should be ablt to see it steam as the motor starts to get hot. makes you think it's the water pump but it's not. a good parts store can check it for you and sell you a replacement. it's dead simple to replace.
I see it now. No probs on my 7M-GE!
Hachiroku there are several of those small coolant hoses on your Supra. One of them that you should keep an eye on is just a pipe end cap. It should be on the exhaust side of the engine near the firewall.
When I had the top off the engine, I checked out all the hoses and tubes, esp after the PCV and oil breather tubes broke trying to remove them.
Everything looked OK
yep, that's my motor too. a leaker can really make you think the water pump is bad because of where it steams.
