I'm looking to trade my labor for a toyota Sunland express camper. My wife and I are looking for a project to restore but while inspecting the camper 22re engine I noticed an antifreeze leak on the front of the engine. I know this is vague and I'll admit I'm no pro when it comes to this engine but any help or knowledge would be greatly appreciated. Basically I'm willing to do the work but am just looking for any ideas as to why the engine would be leaking antifreeze. Thanks in advance for any help.
