Ford Mondeo Mk3 2.0 TDCi 130 - Low running temperature
I thought I'd pass on my experience with a my 'cool running' Mondeo. Last winter I had the same problem with the car not warming up properly and changed the main thermostat for a non genuine item. (the Ford one is around £50!!!) This made no difference whatsoever. The weather warmed up soon after and as I wasn't cold any more I gave up. Then came the current cold spell and the problem remained so I bit the bullet and bought a genuine one, no change and fifty quid worse off.
Looking on various forums I discovered the second oil cooler thermostat and bought one from Mr Ford. (just under £20) After fitting it this afternoon my temperature gauge runs smack in the middle and the heater is toasty, yipeeee!!!
The hose that exits from the oil cooler enters the radiator on the right hand side about 1/3 of the way up and should remain cold until the engine is warm, mine was warm all the time so was taking heat from the engine to the radiator even though the main thermostat was closed. When I removed the old oil cooler stat and blew down it it was open even though it was cold. I would guess that to eliminate the second stat as a cause of over cooling the hose from the oil cooler to the rad could be temporarily clamped with a brake pipe clamp or similar to simulate the stat being fully closed,
I hope this helps someone else to stay warm this winter, good luck! "
