This pain began over two mths ago when my triton started overheating under load and up long hills not boiling just damn hot. Since this saga began I have replaced with all new parts the radiator, most hoses, fan clutch, termostat and good quality coolant to no avail. When I changed the water pump I noticed the timing belt was slack around the waterpump I could spin it free hand. So I have replaced the timing tensioner but it still runs hot up hils under load and when a/c is on so I'll be pulling apart again (3rd time) to check if it's still slack around the waterpump on the weekend . I would love some advice or opinions on how to make it tight around the pump pulley as my Brain has had enough thx adam
