With 320,000 miles on my son in law's '93 Trooper, it has developed a leaking heater core. Coolant is dripping down the passenger side carpet area. Replacing the heater core would cost more than the trooper is worth. The transmission is shuddering and oil usage is considerable. He just wants to get a few more years out of it. It's not his daily driver. It's just his first car so he has an emotional attachment to it.
Are there any "stop leak" products that are worth trying?
