Wath sice of rim us the 1987 jetta standard 4 doors?

You could try to just cut out the bad part and solder in the new wire to the good part of the old. Also clean up the affected area.

well lucky for you VW only made one engine for a Jetta in 1987, 1.8 so the temperature sensor is on top of the water outlet on the rear of the cylinder head , also called water flange, it is the sensor with the most wires, normally 4 wires.

TAKE PANNEL OFF IN SIDE AND SEE IF IT HAS A QUICK RELEASE OR IF THERE IS A BAR YOU CAN PULL OR PUSH TO RELEASE

This car used 13 inch wheels

That is a question you ask at the auto parts store

I would look to see if one of your balancing weights on your rim has fallen off. they are usually lead and on the inside of the rim. Does the shaking increase with rpms or with speed? Is there certain speeds it stops shaking?

2008 BMW 323i 4 door sedan - factory wheel rim size

Rim size (standard factory spec):
16 inch by 7 inches wide.
Front and rear are the same size.

(It is possible to fit 17 or 18 inch rims to the car if you wish together with an appropriate lower profile tyre ).

(please note that different models in the 2008 3 series BMW have different size rims. For example, the 328 and higher level models runs larger rim sizes).

Hope this helps. Cheers

varies but 28 psi minimum but to keep the edges of your tyres from wearing I recommend 34-38 psi if youre happy with the ride

Why not let the salvage do all this for you and buy them there

The cause is the Brake Master Cylinder. Replace the Master Cylinder and you will need to Bleed the Brake System also. If you have not done this Before, I would recomend a Pro Install and Bleed the System for you.
