Starter R&R

[Harmonicashawn]

I'm sure this has been covered, but I thought it bears repeating. My starter cranked very weak. All connections were great and little loss through the solenoid. Skydoc_17 suggested that I install a VMAX starter (4 brush vs. 2 brush), which he sold me at discount (thanks). This Totally solved my problem-period! I read a tutorial somewhere that detailed removing exhaust pipes (it's not that involved and you don't need to disconnect the exhaust)! You DO need to remove the radiator and lower hoses. The bypass tube leading from the thermostat housing and the housing itself (remove the plastic elbow from the water pump and take the entire assembly out). Use new O-rings for everything and use some vasoline to lube them (or something similar). I have a first Gen and I needed to remove the air dam and it was easier with the right side crash bar removed. I spent about 3 hours, but I changed the thermostat and did some other things as well. I should have taken pictures, but that would have cut into my drinking time!

I agree with all you have said except the starter its self. I just completed all you said and upgraded to 4gauge battery cables along with a 2 brush starter with ground upgrade from Dingy ( thanks again ) and now my 89 cranks over at unbelievable rate. Also I switched to an AGM battery with 350 CCA. I am glad you solved your weak cranking issues as have I.

Any 4 brush will work better! From what I understand one from a 2nd gen bolts right on, but I may be misinformed...

Bob you are right. I picked up a 2nd Gen starter for just this reason off Pinwall for $50 and it works fantastic. spins really fast no matter how hot my engine is.. Very happy with the results and bolts right on..
