My dad drove car yesterday and said the car started to smoke under the hood just as he arrived home. So today I checked all of the fluids and everything was fine except it was very low on antifreeze. SO i bought Toyota antifreeze and added the whole gallon into radiator and reservoir. Went for a test drive and the car started to overheat within 15 minutes and it started to smoke under the hood. I oppened the hood and I heard like "wooosh" sound where the smoke was coming from kind of sound when you pour a water over hot pipe. The smoke is coming from the back of the engine behind intake manifold. Any thoughts??? I cannot have car checked before monday.

hmm check heater core hoses by the fire wall

is it loosing fluid? maybe there's a leak in a hose, dripping onto the exhaust mani? there's SOOOOOOOO many things it can be

definetly a leak if there is smoke from engine bay.. was there a puddle under the car when you came out next morning?

Check the heater hose way in the back of the engine by the firewall. When my car was constantly overheating i found out it was that hose that was cracked. like deknick said it could be a lot of things.

Well thank you all for help. I did the pressure test and found the coolant was leaking from one of the hoses. Did the custom hose and put it on then I replaced the coolant with Toyota Red Long Life and baby runs like brand new again

glad to here you got it fixed.. this is good info for future overheaters...lol

Yep check you HOSES people please.

Same exact thing happened on my Supra when I had it. Two friends and I had to push it uphill about 100 feet night on time and that things a tank!

Glad to see you did get it fixed. +1 for checking your hoses, especially in older cars. Imagine if it popped on the freeway or something and you couldn't pull over immediately or something.
