1988 Acura Legend; about 3 months ago my engine was over heating. I changed the heat sensor and it ran fine. now the same problem is back, the car over heats every time I drive it, the fans never come on. I keep my coolant and oil on full so I hope I have not hurt the engine. is there any way to fix this problem or perhaps to bypass the thermostat sensor?

Suggested Repair

Start diagnosis with the cooling fans that never come on, and check fan operation and the fan relay before considering other cooling-system parts.
