ok guys i have a 1989 toyota pickup 4x4. its got the 22re motor in it. well im not sure what the problem is but i just bought it yesterday and it keeps wanting to overheat, and now it wont start at all. it just turns over and doesnt start up. the radiator has fluid in it, and its not leaking out anywhere so im not sure what it could be. if anyone can help by telling me what might be wrong i would appreciate it. Thanks guys!
