Re: water pump?
Could be a plugged heater core also. You can unhook the heater hoses at the firewall and reverse flush the heater core.

Re: water pump?
I put a 90 model pump on it and it's working now. It had a 96 on it. has the two outlet/inlet already on it. Must be the way they plumbed them. All good now
