Hello Guys,

I have a 96 disco se7 that starts to overheat after driving for awhile. Seems to do it after coming off the freeway. Holds temp fine around town. I havedrips of watercoming out of the tail pipe and white smoke (doesnt smell sweet to me). I was told it was head gaskets but want to make sure. Is there anything else that would cause this? The pump is said to be fine. Has new brass plug and resivour cap, thermostat. Hoses seem good. Dont see any leaks any where.

Thanks

 

One More thing! The car has a 115,000 on it. And I have the service records since it was new. Seemed to be well cared for.

 

Are you front electric fans running, how about your manual fan, is the clutch still working?
Go have your coolant system pressure tested to determine if you have a coolant leak.

 

yes the front fans run with the air turned on and the manual fan is runnung when I looked at it a few times. I would have the system pressure tested but they have already tore the heads off. I am going to have it towed out of there as they did not get my permission to tear it down. So I have to proceed from there.

Thanks

 

The clutch fan runs all the time so just looking at it wont tell you a thing. The clutch on the front of it locks up and turns the fan faster when it is hot.

 

So how do I test the clutch fan?

Thanks

 

With the engine off and cold you try and spin the fan by hand, it should turn freely, to much resistance and the clutch is bad.
They already pulled your heads off, so now you have to have new head gaskets.

 

Shouldn't the shop fix it since they tore it down without direction....

 

No. If they do it will be with old parts.Maybe he can broker a deal, he pays for parts and they do free labor.
Read the work order, what did you sign for when you dropped it off?

 

I told them not to remove any parts. I just wanted them to pressure test it, check compression. But at this point I just want it out of there. I did run down and look at the fan and it seems to spin freely. Can I just take the radiator out and have it tested for leaks?

Thanks
