Question about 2007 Mazda CX-7 Grand Touring

1 Answer

I would like to know how oil flows through the automatic transmission and please designate which of the two pipes that connect to the oil coolers is output and input.

There are two pipes that connect to a black round cylinder which feeds oil to both the bottom of the radiator and an external cooler housed in the passenger side fender. I would like to know which of the pipes coming out of the transmission to the black cylinder is output and which is input.

What is the oil pressure of transmission fluid for Chevrolet express


I think it should be between 30-40. Not sure why you need to know because it should be covered under the powertrain warranty, if you are under 100k.

Where is the oil cooler located? Does it have a water jacket?


if you are referring to the oil cooler for an automatic transmission, then it will mostly be in the radiator bottom/side tank and uses coolant to cool the oil. They have a habit of cracking/leaking and putting red oil in the radiator or allowing coolant into the transmission. The fix for this is costly flushing of the engine system and transmission and a new radiator. I would consider an air cooled oil cooler as they are more efficient and not prone to coolant problems.. They are generally cheaper than a radiator as the inlet/out let pipes can be blocked off

Does my jeep 3.1td 2001 has a water oil cooling?


some cars are designed with an engine oil cooler that allows radiator coolants to run through it to aid cooling the oil for longer life. and most of the radiators are designed to cool automatic transmission fluid which is routed through an oil cooler in it.

    2001 cadillac catera: oil in coolant?


    The Problem, My friend, is a leaking oil cooler. this item is mounted, inside the engine, under the intake manifold. The cooler or the connections are bad. Coolant flows through the cooler, if it brakes then the oil will contaminate your coolant and make a mess.!! Have it checked. Must times is the seals at the pipe to cooler flange connector. will need new seals.. Hope this helps.
