Today i got in my 4runner and drove about 5 mile and parked and went inside when i got back out about 10 mins later i had a huge puddle of coolant underneath her so i popped the hood to see if i could find where it was coming from but had no luck. as far as i can tell its coming from the area im pointing at (behind the plastic cover) it appears to have sprayed up because the coolant is on the underside of the hood as well all over the top of the moter (mostly driverside) can anyone please assist me in finding out what is going on? checked my coolant reserve and it was completely empty drove back home and temp gauge was normal everything drove okay as well??? idk what it is!!!
