I'm replacing my Renegade/Chrysler BB pump, since it locked up last night. I didn't here any noise at all ? The engine does make a bit of noise but you would think there would be some warning. Nope ! Maybe something broke off and jammed up the impeller etc. The pump just locked up and melted the drive belt. My question is I have been running a standard pump and decided to get a high volume unit. My assumption is the quality is better than my last one and with A/C it might perform better moving more water. I guess with more pressure comes it own set of issues. One thought is the belt was too tight, and that's a good bet. I'm not running a Thermostat but am running a minor restriction in the thermostat housing, which I think I should remove.. ? Any one have any input here. (IMG:style_emoticons/default/type.gif) |

I'm not sure of anything that's the reason for testing different ideas. I run my engine between idle and 4500 rpm 99% of the time and don't run a thermostat, the rev limiter is set at 5k so when I get off a AS* I'll install the new pulley and let you know how things turn out..

don't run a thermostat: When I spoke to you at Slits place (Rustmeat) a couple years ago, I remember you saying that you didn't run a theromstat. I forget...why? I have a thermostat with three air bleed holes drilled in the housing per Renegade instructions. What would be the pros and cons of running a thermostat? |

I ran a thermostat as most V8 guys do with out any water pump bypass. Chevrolet stock setups have a water pump bypass to keep pressure from building up before the thermostat opens. About 2 years ago I revved the engine cold and my water pump impellers bent. From that point on I haven't run one. I'm sure its better for the engine to run one, its best to keep an engine at a tight coolant temp range, but for now I'm not. I do understand about the holes drilled in the thermostat and that does work fine. I have started working on using the holes in the heads where you can plum water to a tee to act as a bypass, just haven't done the work.. Once I do that I will run a thermostat. If its working for you by all means run one.. (IMG:style_emoticons/default/aktion035.gif) |
