It's Deja Vu all over again. 1995 V940 250k, 8-Valve NA.

October of last year.. Wife's 940 was loosing coolant mysteriously. I traded cars with my wife and took the 940 to work. On the way to pick up my kid from school, I started losing coolant rapidly. I discovered that the heater valve had broken in half. I managed to "macgyver" a solution that got me to a random parts store and then on to the school.

I ordered replacement valves from IPD (ScanTech) and Tasca (OEM Volvo). Scan tech got here first so I put it on. OEM part arrived late, so it went into the "emergency parts" bag in the smuggler's compartment.

In the spring, I upgraded to Red Silicone Hoses from a group buy on Turbobricks.com. Great stuff, really. Also replaced the Headgasket back in March.

So this morning... the Scan-Tech valve lasted for about 14 months and then snapped off with little to no warning. I made it about 10 blocks from home this AM when the coolant light came on. Pulled over, topped off the reservoir, saw the lead... and headed back directly. No damage

I put the OEM valve on... but I've got my concerns about it. See... the OEM valve is all-plastic and looks 100% identical to the ScanTech valve. It came in a sealed Volvo Bag, but looks exactly like the Scan-tech. The original was metal and plastic. This one bothers me...

Despite its similarity to the Scan Tech, is this valve, in-fact, good quality?



Is there a better option available for these cars? OEM or not, I don't trust the ScanTech-looking valve.
