I just picked up the Miniram II from TPIS. In my engine bay, there's 2 hoses above the passanger side valve cover that go to a divider with a vacuum line on top. From the divider then goes into the throttle body. I know that on the TPI, you can by-pass that straight into the manifold. On the Miniram II, there's no coolant inlet from throttle body that you usually would use to by-pass the coolant for the throttle body. Where do you guys reroute this coolant hose to?

These instructions came with the Miniram. The thing is, the stock manifold has provisions in front for 2 sensors and a third provision for coolant return. The Miniram only has 2. Well, I have the sensors there right now. Now where's the coolant return going to go? Am I suppose to sacrafice one of the sensors for the coolant return? I don't know, for that amount of money, it feels kind of half-@ssed to me. When I purchased it from them they mentioned the EGR and the coldstart injector being deleted, but this wasn't mentioned.
Thanks for trying to bring some insight to this though GTA324.

 

Hey 88l98z, since you have a REVERSE ROTATION WATER PUMP, you could just remove that plug in the top of the WATER PUMP, install a 45 degree (male/female) BRASS PIPE fitting, and return the heater core coolant there. That is what I did on my Monte SS with the 88-92 Serpentine setup. The Monte doesn't have the extra fitting on the RADIATOR for coolant return, so since that normally plugged port on the top of the REVERSE ROTATION PUMP is a SUCTION, it works fine. It will work fine for your MINI-RAM also. HTH's NO PROBLEMS with HEAT

88SS6SPEED, I was thinking of doing the same thing also but I do have a
problem with that. By connecting it to the top of the water pump like that,
I would be reintroducing hot water back into the block instead of the
radiator. I believe that originally routed from the factory from the
throttle body to the manifold because from the manifold, it would be routed
to the radiator.
Because the water pump on these cars are reverse rotation doesn't mean that
the cooling system is reverse flow. The pump will still flow water into the
block first, then through the heads, then from the manifold back into the
radiator. If it were reverse flow, the water would be flowing from the
heads, to the block and then to the radiator.
I noticed that one of the water lines from the oil cooler feeds to the
radiator. I'm not too sure, but I think it flows water from the cooler back
to the radiator. If that's the case, I guess I'll have to tap it into there.
Thanks for all the suggestions though. I just can't believe that I'm the
only one that has come up with this problem. There's got to be more Miniram
owners out there that might be able to help.

 

Hey 88L98Z, I can prove it works. On my original Monte carlo setup, the heater connections were hooked to the water pump AUX outlet and to the intake connection. When I got this engine with the 88-92 serpentine setup and REVERSE ROTATION PUMP, I also got a radiator with the 3rd GEN style AUX 5/8" heater hoe return. I hooked up my heater hoses in the ORIGINAL configuration, water pump AUX fitting and return to the RADIATOR. I was living in VA. at the time, and I was FREEZING, NO HEAT what-so-ever. I changed radiator to one without that AUX 5/8" return barb, plus changed the configuration to INLET from the FRONT of the TPI base and return to the AUX connestion of the REVERSE ROTATION PUMP, and heat has been working fine ever since. I know for a fact that that pump connection is a suction. HTH. BTW, I never said anything about REVERSE COOLING. That is strictly 2nd GEN only.

Regardless of pumps (unless your talking reverse flow Gen II) the aux barb on the water pump will always be suction and the connections into the block will always be outlets. Reverse rotation pump impellers are needed when the belt raps from the bottom of the pulley instead of going over the top. On the miniram question, one of the two coolant sensors is a switch used for the cold start injector which the miniram doesn't use. Leave that sensor out and install the hose barb. The cold start injector switch/coolant sensor is the larger sensor with a rectangular connector similar to a fuel injector connector. You will need a custom chip with the miniram to add extra fuel through the main injectors for cold starts.
