Got a buddy who's having overheating issues with this 94 Toyota Corolla. He says he doesn't see any leaks in the hoses and the reservoir isn't cracked. Any other ideas?
Car's overheating, but it sometimes cools off, then goes right back up when
sitting or being driven. What could be causing this? It sounds like a thermostat
issue to me, but I want to give him good advice. Help?
