electric motor cooling

[Martin Benade]

Simply throw a rag into the engine compartment, it will find its way into the fan. I know this to be true. Pull it out of the fan once the engine is hot. Just don't expect any heat blowing from the ducts. Also I imagine in cold weather blocking the oil cooler might not do enough, cylinders and heads also need less cooling.

maybe do exactly what the big rigs do and place a piece of plastic over the grill in the engine lid? That would warm up the engine bay, thus increasing the temp the engine sucks in to cool.

Adding an Ebrespacher heater is way too complicated - see the photos below for what is needed to add an Ebrespacher B2 in the rear of a T1 thru T5 car.

There have been threads previously about partially blocking the fan inlet (with something that would not get sucked in) and I believe it produced the desired result of higher oil temperatures. Albeit at the expense of less air flow thru the heater boxes to keep the driver warm. If you want both warmer oil and a warm driver then you need the Eberspacher ......

I had a gas heater in my first 911 (1966). Having come from a 356 where I was always cold I thought it was going to be great but I was disappointed because I worried about a fire. It started irregularly and made noise that was concerning. That said the 911 effectively had the European heater and it was more than sufficient. Is it not practical to add the European heater to the pre-C cars?

Noticing a couple of answers about disallowing water in the engine; Are you 'fording' creeks or ponds during a drive?
Also, a quicker warm-up of the engine would happen if you drive the car moderately after the oil is primed thru the engine--about several minutes; In many states, it's illegal to warmup the car for 5-to-10 minutes w/o you in the car while parked on the driveway or the street!

For a quicker warmup, just turn on the heat by closing the 'flapper boxes', but DON'T cover the fan's air intake!!!

[Dick Weiss]

BTW, any water exhausting isn't from the engine; It's condensation from the cold exhaust system which eventually rusts the pipes including the exteriors.

[Martin Benade]

I think the mention of water was about condensation in the oil. As to closing the flapper boxes, I had overlooked the obvious, I bet that lessens the volume of air over the cooling fins and oil cooler pretty effectively.

hi
how about using a electric clutch pulley on the generator like you use on an air conditioning compressor'

Interesting Jacques!

Eberspacher manufactures modern gas-fired heaters that are compact, efficient and far less complex than the older BN 2 and BN 4 series. Still used in boats, trucks and planes around the world with no problems.

[Martin Benade]

Some VW drag racers use a clutch pulley, but that also cuts out the generator. As for modern Eberspachers I think they cost thousands of dollars but otherwise a nice idea. They would still need most of what Bill pictured, various fuel lines, exhaust parts, brackets, and ducting for the hot air.

That would work, but you need to make it fail safe so that the clutch automatically reengages when the battery voltage drops off. It might be a better idea to put the clutch on the fan end of the shaft.

My 1959 SAAB 93-B had a hand operated shade that pulled over the grill (Like a big rig). Operated from the drivers seat via a pull cord. That 3 - cylinders still produced no heat in upstate NY. The Swedes were hardy people. That car was to be an upgraded heater from my 1955 Renault 4-CV. Also no heat. ..............Jim.

PS. No problem in So. Cal.

[Jacques Lefriant]

Hi being in So Cal I have no experience with the cold conditions but hasn't multi viscosity oil facilitated these worries?

Its 9 degrees here, my car is sitting happily in the garage with not a care about oil temperature or viscosity. No worries.
