Heater Core Pump

[revhead347]

I drove 130 miles today in sub freezing temperatures with ice on my windshield almost the entire way. I didn't really care that I didn't have heat in FL, but now it's getting a little rediculous. Anyone know where I can get a decent heater core pump that will fit on our cars?

Okay, I'll ask, what is a heater core pump?

your regular WP is what circulates water through the heater core. your core may be clogged. try doing a flush on the core or the whole system.

No, I have one of those Mr. Gasket big ass thermostats in there, and none of the water gets up to the heater core. Some stock high performance engines have similiar problems, so you'll find that some Mercedes and BMW have a little electric pump that helps circulate water up to the heater core. I'm trying to see if anyone has found one that fits nicely on a Mustang.

A big stat causing no fluid to get to the core? What is a big stat? If its some kind of superflow at a low open temp you may be using a stat as a band aid for an otherwise not up to the task cooling system overall. You can have issues with say no stat, very low temp stat, or stat that is not working correctly keeping the temp too low and causing issues.

Sounds like your either low on coolant, a bum stat, or have air bubbles. There is no reason the WP would not flow coolant to the heater core as it is a direct cooling system pressure/displacement of fluid by the pump process. The electric pump your wanting will only do what the WP already does by design.

I have a high flow water pump, and a huge aluminum radiator. The only way I was able to keep the car below 200 degrees in traffic in FL, was to put a Mr. Gasket hi flow thermostat in. Which immediately fixed the overheating problem, and simultaneously killed the heat in the car. I've even blocked the flow in the bypass hose. Nothing gets the water to flow up into the heater line, it all goes to the radiator. Putting a small electric pump in the heating system should fix that though.

I also have the same set up as you but believe me, heat from the heater is not an issue. If you are not getting heat there may be an obstruction in the lines or the heater core. I'm also wondering if the heater and bypass hoses were reversed off of the water pump.

 

[revhead347]

Ok, maybe I'll check for an obstruction if your setup is working fine. The hoses aren't mixed up. That bypass hose is so short, I can't imagine even being able to mix it up. It's just weird that I would get an obstruction simultaneously with the thermostat change. But if you have the same setup and no issues, it's worth looking into. What temp thermostat are you running?

180* hi-flow.

Thanks.
