Heating & Cooling Tech Tip

By: Rob Arnold - ipd research and development and special projects manager.

My newly purchased 1994 850 seemed to be the perfect car, two minutes after signing the title the heater core started leaking. That explains the hurry the previous owner was in for me to drive off. Fortunately heater core replacement in these models is actually pretty easy. I was surprised to find that the new Ipd heater core I bought had this message on a big red warning tag when I pulled it out of the box. “Electrolysis is the transfer of metals in a cooling system caused by either ionized coolant, or incorrect engine grounds. The electricity flowing through the coolant system can cause pinholes to form in the heater core and/or radiator. Proper servicing of the coolant, and correct installation of the engine grounds should eliminate electrolysis.”

This got me thinking about how a little cooling system maintenance by the previous owner might have prolonged this unsavory task. Immediately after that thought, I noticed my 240 in the driveway looking a bit forlorn as I spent all this time with this newcomer to the garage. To prevent a spat between the two, both got equal amounts of cooling system attention in regard to the condition of the coolant.

How do I test to determine the condition of my coolant in respect to electrolysis? The best way is to start the engine and take a digital volt meter on DC voltage setting and place the negative lead of the meter on the negative battery terminal and place the positive lead of the meter into the coolant. A voltage reading above 0.300 volts DC can cause pinholes to develop in the heater core or radiator. Be careful when running the engine without a radiator cap on and never open a radiator cap when the engine is hot! The simple fix for acidic coolant is to flush the cooling system with fresh coolant as well as using a product that helps clean and balance the PH of the coolant like Water Wetter from Redline. Check out Redlines excellent web video on cooling systems using Water Wetter at www.redlineoil.com/products_coolant.asp

Waterwetter Supercoolant by RedLine

WaterWetter is a unique wetting agent for cooling systems. It reduces coolant temperatures by as much as 30¼F. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass and bronze systems. Compatible with all antifreezes, including the latest long-life variations. Does not alter the freezing point of water, so at least a 20% anti-freeze solution should be used. 12 oz bottle will properly treat the cooling system of one car

Samco Hoses

Silicone hoses can be one of the most affordable and easy upgrades to any vehicle, especially turbo models. Many factory hoses are made of plastic or similar materials that allow massive amounts of flex which translates to a fluctuation in boost pressure. Quality hoses are instrumental in maintaining steady boost pressure as well as containing it under higher than stock levels. Samco hoses meet the standards we all want. They are hand-made on dedicated mandrels and are pressure tested up to and beyond 50psi on most sizes and applications. They maintain the highest quality standards and product testing to ensure they produce the best product available.

Engine Coolant Sensor

If you’ve noticed a check engine light on your 850 or 70 series Volvo and the ECM stores code 123 for the engine coolant sensor (ECT), here’s your answer! The ECT resides right underneath the thermostat on these vehicles which has been known to set a code for the ECT itself. The root cause is normally a thermostat that won’t fully close.

Replacing the thermostat solves the problem, although most repair facilities will recommend the ECT as well for good measure.
