Re: Help with Radiator / Water Pump

If you're dishing trade secrets, I'd love to hear about the hammer and chisel trick. Sounds like we've got some time to kill on this thread ... Not really a secret, just something I wouldn't have thought of on my own. Works best on screws/bolts with thick heads, like the fillister-type head on the ...

Re: Help with Radiator / Water Pump

Thanks for all the responses! Here is an update. 1. As I expected, 3 of the 4 socket/allen head screws holding the pulley on the water pump stripped once I put some real force on them. Thankfully a great BMW mechanic in Memphis (John Cox) showed me how to break loose stripped screws/bolts with a chi...

Re: Help with Radiator / Water Pump

While we're at it - how did you test your sensor switch? Did you suspend it so just the threads were in water, or was the sensor face contacting the pan? If the latter, you might be measuring the temperature of the pan, and the sensor could switch only at a much higher temperature than spec., so in...

Re: Help with Radiator / Water Pump

Now I’m curious- do cars without A/C have an auxiliary fan? I thought it was for cars with A/C and only came on when using the air. Also, have you bled and re- bled the system? The symptom of the temp dropping at higher revs sounds like a circulation issue. Or, is the motor modified beyond the head...

Re: Help with Radiator / Water Pump

Thank you Joe! My earlier E12 only has a single stage fan. When I jump the wires at the temp switch, the fan comes on. Could there still be a problem with the relay? I also tested the new switch in a pot of water on the stove, to make sure it works (it does). Good idea regarding the thermostat. My p...

Re: Help with Radiator / Water Pump

Wow - this is a surprise to me, so I can only imagine how you're feeling! The aux temp sensor is below the outlet of the rad - is it at all possible that there is an occlusion just above the sensor? That wouldn't show up on a flow test. Can you shine a flashlight in the sensor hole and see light th...

Re: Help with Radiator / Water Pump

Update: Picked up the radiator from the radiator shop today. They cleaned a lot of grass out of the fins but the flow test was fine, so the car may run a little cooler but no help regarding why the aux fan will not come on when the temp gets hot.

Re: Help with Radiator / Water Pump

Mike, Here are the symptoms: Car eventually gets hot when idling or in heavy stop/go traffic. I've never let it boil over. Revving the engine cools it down. Once it's hot, driving it in a lower gear, so the RPMs are higher, will cool it down faster and keep it at a lower temp. Temp is fine driving o...

Re: Help with Radiator / Water Pump

Mike, Thank you for the great info, as always. One of my usual online parts sources (maybe AutohausAZ) has a Graf water pump. I'll verify that it has a metal impeller. I took the radiator to a local shop at lunch. After describing the symptoms, the owner was almost sure the problem is not the radiat...

Help with Radiator / Water Pump

I've been having a cooling problem since buying my E12 in 2016. It doesn't overheat quickly, but eventually does. I realized the aux cooling fan does not coming on when the temp gets high, but it does come on with the A/C. Replaced the temp switch and that didn't fix it. Jumped the switch leads and ...

Re: Shocks n' Struts

Only tip on a spring compressor would be, don't crank them down any more than you need to. Upper strut mounts, yeah they got expensive, yowzer. I do see them significantly cheaper, but still no bargain. I have ordered from them before and was happy with the purchase. http://old.schmiedmann.com/disp...

Re: End Caps for Wiper Arms

I wasn't able to find the end cap. As the cap has a pin that runs through it. I ended up purchasing new wiper arms for both sides(L&R). I found the right side at Schmiedmann.com for 36.00 as the part # changed to 61 61 1 370 020. I had purchased the left side at ECS tuning part #61611370025 for...

End Caps for Wiper Arms

I'm replacing the rubber damper rings on my 530i wiper arm shafts, which means I need to remove the wiper arms. I notice that one of the end caps (covering the shaft) is cracked, and I'll probably crack the other one taking it off. I would like to replace them, but the RealOEM diagram does not show ...

Mine was also leaking when I put in more than 6-8 gallons. No rust anywhere on the bottom of the car, but the filler neck had rusted where it meets the tank.

Just finished this same project on my '77. It was actually easier than I anticipated. I tilted the tank forward and then just wiggled it out without a problem. One thing that helped on the reinstall was using a floor jack, old riding lawnmower tires and blocks of wood to elevate the tank into place ...
