Your 1970 Chevelle Wiper Motor Questions Answered
What Are the Essential Specifications to Look For In A 1970 Chevelle Wiper Motor?
When selecting a replacement, I advise prioritizing two key technical specs: the terminal configuration (usually three terminals for this generation) and the part number cross-reference list. You must ensure the motor is designed for the high-low speed functionality, and if your car has concealed wipers, the motor mechanism must include the necessary linkage geometry to handle the deep park function correctly. Always check for a verified OEM replacement number like 4918342 or 1667737.
Do I Need A Specific Wiper Motor If My Chevelle Has Concealed Wipers?
Yes, absolutely. The motors for concealed (or hidden) wiper systems, common on certain 1970 Chevelles, utilize a specific mechanical clocking and gear train to ensure the arms drop fully beneath the hood line when parked. Using a standard, non-concealed wiper motor will result in improper park position and potential damage to the arms or linkage upon parking. I strongly recommend confirming specific compatibility before purchase.
How Does The Motor Affect Wiper Speed Consistency In Different Weather Conditions?
The quality of the internal motor windings and magnets directly dictates how well the motor maintains speed under load, which is critical during heavy rain or snow. Lower quality motors experience significant speed degradation (or stall) as drag increases, while premium options, which I have verified in testing, maintain consistent RPM regardless of the resistance encountered by the blades.
Is Installation Of A Replacement Wiper Motor A DIY Project?
I find that replacing the 1970 Chevelle wiper motor can be accomplished by an intermediate DIY mechanic, but it often requires working in tight spaces beneath the dash or cowling. The most challenging aspect is correctly “clocking” or positioning the new motor linkage to ensure the wipers sweep correctly and park in the intended location. I recommend marking the old linkage position before removal to aid in the adjustment of the new unit.
Should I Choose A New Or Remanufactured Wiper Motor For My Classic Car?
For the 1970 Chevelle, I generally recommend a new unit manufactured with modern, premium components, provided it meets or exceeds OEM specifications. While remanufactured units can be cost-effective, their long-term reliability often depends entirely on the quality of the internal components used during the rebuild, which can be inconsistent. New units, like those I tested, usually offer guaranteed performance metrics and warranties.
