There is no ground wire for a radiator. It isn't an electrical part. It consists of aluminum fins and a composite tank on top and bottom.

Morning guys, I've a problem my Nissan navara 2,5 dci 2007 model it's first have radiator leak after changing radiator now it's overheats and pushing water back on radiator cap. What can be a course

Are you sure the original radiator was bad? If it leaked did you try to use a leak stop product? If so did you flush the engine to remove said product? If you had an overheating problem before, there is a possibility you have a bad water pump, or thermostat.

My 04 Altima 2.5S AC compressor wont engage, I took it to an AC shop and he told me he checked the pressure and everything is ok... no leaks. the compressor is not getting any power as well as the radiator...

You would need a shop manual for the wiring diagram for the ac to troubleshoot it.
There is a low pressure switch and a relay involved that could prevent the clutch from getting power. The radiator fan runs when the ac is running and high pressure is above 200 psi.

I have no idea why he would say your catalytic converter had something to do with a loss of coolant unless he was just saying it was a seperate problem. You need to check all your hoses to make sure theres no leaks. That is the most common problem when coolant is being lost. Wherever you park your car normally look on the ground for stains. If there is no stains and if your head gasket is good, you may have a bad radiator. You should get a pressure test done to get a better idea.

1998 Jeep cherokee Tranny leak

The best thing to do is to jack it up(use jack stands) so you can get under it, start it up and look for the leak, from the way it sounds it should not be hard to find, look close at the trans. cooling lines they run from trans. to radiator, and also where the dip stick tube goes into the trans. And last the oil pan it could have a hole in it or the gasget is bad.

open hood pull out oil dip stick, if oil looks like coffee with cream it is possible that the head gasket is bad. if the oil looks a normal color the cooling fans could not be working .have a radiator pressure test done to determine where coolant leak is.

Take it to your auto parts store in town (call around to find one that can before you leave your driveway) and have them do a radiator preesure test. Won't cost a dime. If it pressure to 30 p.s.i. and holds, you more than likely don't have a problem and the techs were pointing out a previous problem and didn't know it had been repired.

1993 Audi 90 cs Quattro Screwed up!!

Regarding your radiator leak, some can be fixed but plastic radiators usually get replaced. A 1993 probably would need a fan switch by now if it was never replaced especially if it's the fan switch that is screwed into the radiator and is exposed to coolant. Again, a car this old would probably need a new water pump too but screwing up the valves is definitely his fault and should pay for all repairs. I'd have someone else do the repairs like the car dealer and charge him for it! Take it to small claims court if necessary. Lastly, if you signed an invoice to just have the radiator fixed and nothing else, your case is strong. If you signed an agreement giving him permission to do "whatever needed in his best judgement", well, your case weakens a bit in regard to having all the other parts replaced but he's still a fool for bending your valves. Sorry to hear of your encounter with this. Please post the name of this shop for the rest of us will know to stay away from it.
