NEED URGENT HELP WITH 86 325E WITH A 88 325IS ENGINE

[87325]

Yea thats what i figured,I was going to ask before i took it out Thanks Guys

[87325]

I got it guys it was a break in one of the small wires works like a champ now.Would a radiator off a mid 90s 325is fit in my car? 86 325 with 88 i engine?Thanks

i was kinda right about the right post getting power just didnt tell you to check for power there.

the radiator will fit but you will also need to mount the coolant bottle on the other side i also think you would need to change water pumps not sure on that last part

[87325]

Well the 2.7 rad. works its just that the ports on the rad. are in the wrong spots the driver hose is on the bottom and the pass. is at the top i need the opposite. Why do you think i would need a diffrent water pump?

[fourdoorfanatic]

because the entire system was revised when they changed radiators. on yours the coolant resevoir feeds the h20 pump. on the late model it feeds into the tstat area. everythings on the wrong side of the engine bay. you would need hella long radiator hoses and all that would be running between the radiator and engine. not much room there. so, h20 pump, resevoir hose, return hose and radiator at least. if you wanted to do it right you'd get the metal cross pipe too. really not worth it, i don't think theres anything to be gained from it.

On my engine it feeds into the t-stat housing.Its a late 80s engine. I guess i need the rad. to match.

im not sure on the early i motors if they were the same as the later i motors or like the e motors. i know the later i motors radiator have different locations for the hoses

[87325]

Yea my top hose comes off the top of the engine,And the bottom comes off the pass. side kinda There is a hose that hooks up to the t-stat housing on the middle part under the intake then splits and goes t-stat housing then inside car.

[87325]

And does anyone have a extra intake elbow for a 88i engine?

[87325]

I got it, bought a new intake elbow, but its running rough sounds like it has a huge cam in it lol vacum leak? dist.?

[fourdoorfanatic]

sounds like you have the late model stuff then, i get caught up in looking at your info on the right and seeing "86 325e", which is different. if your lower hose is on the right then you are golden, lots of options for radiators. yeah, all 6 cylinder e36 radiators (325i/s, m3, 328, 323, no four bangers, they fit but why a smaller radiator) will straight fit in, they are the same radiators really. the nice thing is the e36 has ALUMINUM radiator options, or more of them, and for a more reasonable price.

austra, 87 "i" cars were a weird lil hybrid in a way, old school h20 pump and radiator setup and no quick disconnect for the injection rail/tstat wiring on the engine harness. i call that little plug under the intake of the 88-on m20's the "zipper connector".

rough running, clean throttle body, check for a vacuum leak on the #6 intake gasket.

[87325]

Thanks yea was told it came from a 88 vert ic. Whats the deal on the #6 intake port?

Yea engine already has the metal cross pipe.
