How do i know if my 1974 vw super beetle is overheating?

i live in tucson az and its in the high 90s. i just bought the vw and not to sure how i would know if its overheating. it runs great just want to make sure i know so if it does i know when and what to do about. any help would be great!How do i know if my 1974 vw super beetle is overheating?a good quick cheap (free) test is the dip-stick test. if you can take the dip-stick out and hold it in your hand for a few seconds then its not overheating. by that i mean, enough time to pull it out and read the oil level. by that time it will be very uncomfortable and you will want to put it back. thats normal. if you cant even bare to touch it, let alone take it out, its too hot. this is an old VW mechanics trick that has been used for years. or like others say buy an oil temp gauge and sensor and mount it in the oil pressure relief valve in the bottom of the engine, NOT in the oil pressure sensor.How do i know if my 1974 vw super beetle is overheating?
Standard shift? Then don't drive in 4th when you should be driving in a lower gear. The fan is always running blowing air past the piston pots so running in a lower gear will keep it cool as the engine is running faster.(so the fan blow harder)

Always make sure that the crankcase has the correct grade of oil as it is the oil that also reduces the temperature. I have never had an overheating problem and yeah I have been driving in the high 90's(even 125) here, but don't forget the car engine is normally a lot hotter(as it is burning gasoline) in order to run -(even in the winter).



Getting caught in traffic tie ups for long periods of time on a slow idle, will heat up the engine more so. If you can cruise, not a big deal. Leave it as the dealer mechanics set it and make sure the air duct hoses to the dog house are always in good shape and firmly secure. Also that all the sheet metal is in place and that the spark plugs have their boots on to close off the spark plug openings.

And that the V belt that turns over the alternator(or generator) is always in good shape and that you have a spare(as the back of the alternator inside the dog house is the fan)



Your good.



If it overheats(it would be a first) the red oil light comes on on the speedo. At that time either rev the motor so that the oil pressure is increased and the light goes out or shut it down.How do i know if my 1974 vw super beetle is overheating?They ran these air cooled engine in the the Sahara Desert with no problem. The air temperature is minor compared to the normal operating temperature, so make little difference.

But the idea of the oil temp gauge was a good one.

I would also suggest adding the kit to relocate the oil cooler, while adding a spin on oil filter.

A deep oil sump is not a bad idea either, as long as ground clearance is not an issue.

The original oil cooler acted like a preheater for cylinder #3, so was not in a good location.How do i know if my 1974 vw super beetle is overheating?
Hook up an oil temperature gauge. The cooling systems are somewhat fickle on the old air cooled bugs, so you should keep an eye on it.
