I was certain it was the t-stat, so the next day i pulled some slack from the heater core hose to cut off the hole and re attached it, then i replaced the thermostat which to my surprise seemed physically just fine, no noticeable damage, it compressed and everything. the main upper radiator hose(leading into the t-stat) was puffed as well. it was squirting out AF at quite a high pressure. (bear in mind this happened a few weeks prior to my new hose leaks) drove home doing about 70 on the express way for 30 minutes, 2 minutes before reaching home smelled antifreeze, opened hood at home to reveal a pinhole on my heater core hose (the upper one i dont know if its return or intake) right after its mating with the nipple on the block. Ok so these responses have made me realize that the hoses leaking was likely a result of them being puffed up that few weeks back and that was a result of overpressurization, and that was a result of…something…something that i may have fixed post puff (the thermostat or the radiator overpressure cap) or something that remains unsung, so here are some details about that experience… What gives? did all these hoses and possibly water pump just fail at the same exact time or could something be going on thats causing all of this mayhem? im so confuseeeed…. BUT… i then noticed that a tiny return hose above the whole timing belt area thats coming off the thermostat has a wet spot under it too…Īnd it gets even worse…after letting it run for a few minutes…the leak in the original area (the one that had the lake under it) completely stopped…and suddenly it started leaking out of the freaking lower hose on the drivers side at the bottom of the radiator?! I added some water to it and let the car heat up to pinpoint the leak… pulled the timing belt cover off, and there are sure enough little pools of AF in around the water pump area…. Now ive been driving it around for 2 weeks, all seemed fine, got home parked it…went inside for 20 minutes, came outside, and there was a freaking lake of antifreeze under my car, passenger side, right under the water pump area. So i ended up replacing the hose, replacing the thermostat, and replacing the radiator cap, all things that i thought may have caused a overpressurization of the system. ok so a few weeks ago i drove my car home on the express way and when i was almost home I smelled coolant, opened up the hood and the heater core hose had breached a little hole and was spewing out AF…all of my other hoses were pressurized and puffed up too, which my car has never done before even after hot long drives.
