I've got a Ford Mondeo Mk.1 1995 model.

Recently, I've had the pump changed. It leaked a little bit after that, probably 100-200ml of coolant per week.

I had a coolant pipe that was slightly leaking (but was patched with rubber in the intermin), so at great expense I had that changed for a new pipe and new radiator put in at the same time. Basically, the entire cooling system is new.

I still have the 100-200ml of coolant leaking per week.

Strange - 1st week I got the car back, it didn't leak at all. But week 2 it's leaked that wee bit.

Leak location - if you had the bonnet open and were looking inside the engine, the leak patch on the ground appears to be coming from somewhere on the left side of the engine bay, the first 1/3 of the engine bay to be precise.

It's driving me bonkers 'cos I've just spent 1K on a car that's worth 200 quid!!!


Any ideas??!?!

 

The only way to locate a leak is to have the cooling system pressure tested.

 

Thanks man, I'll suggest that to the mechanic tommorrow.

What do you think about the dye you put in the coolant system to locate the leak?

 

I have only ever used a pressure tester to locate leaks to be honest. I have been managing fine for the last 10 years in the motor trade....

 

I had a similar problem on my '96 1.8Si Escort. Mine developed a small leak from behind the timing cover area. It was initially diagnosed as a water pump failure but on stripping down and pressure testing it was found to be coming from the head gasket. The bolt on the corner had sheared and was allowing coolant to pass.

 

Get underneath and have a look at the crank pulley end of the sump, theres a coolant pipe runs along the edge of the sump (it's bolted to it) these often rust and become porous, if they suddenly go then the engine quickly overheats and pop goes your headgasket!
