52473676 is printed on the assembly label of the radiator. In the GM part database, it is discontinued, and refers to VPI. And the VPI parts database does not recognize the # Dead end. Are you certain you don't just have a mis-binned item? the number is correct for this item....

One good thing about receiving the S10 in Digest. Any questions are usually answered in the same digest before you respond. This S-10 list is very efficient. This question about the NiMH and how much are you really losing with their efficiency could and should be looked at in...

Scott, I charge in the early morning when it is colder so the air conditioning does not come on. That saves a lot of power. I also never charge right after driving, that always brings on the AC. Stephen On Feb 26, 2008, at 8:03 AM, Jeff Thomas wrote: > Hello, > Jerry is absolu...

Hello, Jerry is absolutely correct about the load influence during heat pump use. Additionally, NiMH chemistry is less efficient than PbA. Approximately .77 to 1 for Ovonic NiMH, comparing to ordinary PbA at approximately .9 to 1. There are additional weighting factors, includ...

Hi Scott, Jeff Thomas can give the best answer to this question. My guess is that the inefficiency of the NiMH truck is due to the large amount of power used to air condition the batteries. I used to lease one of these NiMH trucks for over a year and unless it was very cold ou...

Dave, the test cycle is aborted when vehicle is in run mode. The common method is to place a 10k resistor in series with the front temp sensor -tricking the HTCM into running the FFH when ambient temps are in the 50's. Jeff __________________________________ Sent from my hacke...

Having done all three of these myself just a few months ago, I would say that they don't really require much expertise - but you will need a scan tool and a full set of metric tools (including at least one deep socket - I've forgotten the sizes) and some time. If you are reaso...

Rather than try to trick the sensor to [indirectly?] kick in the kerosene heater, would it be possible to directly relay the kerosene heater to run? Surely some IO board somewhere takes the sensor input and determines if it should turn on the fuel-fired heater, and then throws...

Niel, You can trick the sensor into a more reasonable temperature turn on, but you need to be aware of some of the S10 features. In short you can put a little additional resistance in the thermal sensor line (it is a thermistor that has higher resistance as it gets colder) by...

I don't think that GM got the chance to do much testing of the heater system on the S10EV. I'm finding that the control system has a few bugs. The main one is in the decision on when the use the heat pump or the fuel fired heater. It's supposed to use the fuel fired heater whe...

I don't have the data to back up my opinion, but I think full 100% charging does shorten battery life. On the Toyota Prius, the NMH batteries are cycled between 40% and I think 85% SOC. They could get the most life out of their batteries in this range. This makes sense to me....
