Antifreeze Leak behind engine on non turbo 87 3.0L supra

eandjautoworks · 07-02-2009, 04:41 AM

So, I just picked up a 1987 Supra and I was putting a new exhaust on today and I finally got it done and it started smoking really bad. I looked under the car and under the hood and I could hear antifreeze sizzling on the exhaust. I noticed the water pump is in the front and obviously the radiator and thermostat are as well. I looked at the top hoses for the heater core in the back and they looked fairly new. I am not too familiar with Toyotas and I haven't found any useful information on the coolant system. It is more on the passenger side than the driver side. I was wondering if anybody had a picture of the back of the engine or any ideas where the leak may be coming from. I really would like to get it fixed by tommorow so please give me any information on it that you may know. Thanks.

Hey, I appreciate your help. That site was very helpful. I just needed to figure out what hoses went back there. Thanks

That diagram was very helpful. There ended up being a leak right there at the elbow that goes into a metal line to the head. Thank you

If you can find the room to get there, you might want to replace that heater union bolt that goes into the head there while you're replacing that hose. They tend to corrode, and aren't much fun to get to.
