hey iam back i ahve a 94 ram van 250 v8 5.2l. i ahve this problem that when i drive my van for like 20 minutes it rides fine but when i park and cut the van off i can hear sizzling noise from under the hood and not the radiator just had that fixed its coming from the battery and the bettery was wet like it was leaking the acid so went got a brand new battery and now its doing the same thing what could it be the man at the auto store said it could be the altinator over charging the battery but i never had this problem in all these years no battery befor did that and they all were the same battery so what could be the problem and i had the same altinator for a long time

 

Yes it's overcharging and boiling the acid out. Your voltage regulator isn't working.

 

oh ok thanx man is it hard to install that part

 

For 92 and later vehicles, the regulator is built into the computer. The only way to fix it is to replace the entire computer or send it out to be rebuilt. The computer is easy to replace. Three bolts and three wire connectors and it's changed in under 15 minutes.

 

Make sure you get the "CORRECT" PCM/ECM for the van and NOT the RAM truck !!!

 

how much would this part cost me and does it go under the hood or some where in the van dash or something

 

It's under the hood right in the center above the engine.

Dealer is about $700
Rebuilts are about $250
Used are about $150

There is a sticker on it with a long number. When getting a replacement, this number has to match exactly or you will have problems.

 

YES! YES! YES!

AND avoid any dealers that will sell you a PCM with the wrong numbers!!! There is already one person who has been messed up by this not to long ago.

Here's a few good links on getting a good PCM for your van.

This is a good place to get a used PCM. I got one from them for only $140.

Select "ENGINE ELECTRONIC CONTROL MODULE" for the part type.
