Perfect Fit '95 Astro

form/fit/function exactly like the original part on a 1995 Chevrolet Astro 4.3L (W engine, w/AC). Easy to remove/reinstall, the biggest problem was removing the O/E clamps; used standard screw terminals as a replacement and it was an easy job.

Pros
  • Replacement Parts
Cons
  • I don't remember but there was something

Good idea for Turbo Volvo 7/9 series.

Actually used on a 1994 Volvo 940 Turbo as standard bypass valve blocks flow in (and out of) the heater core and block coolant flow back to the rear of the cylinder head. This simply redirects flow back to the head, bypassing the heater core and helping eliminate hot spots in and around #4 cylinder.

Pros
  • Heater
Cons
  • Secret

Worked great for a while

I installed this in my Volvo in place of the stock heater valve. It worked great and helped keep my head a little cooler. Unfortunately after about 2 years the small metal handle popped out and caused a fairly significant leak. Luckily I caught him before he did any real damage. I'm a little hesitant to buy the same brand again, but at least I know what to look out for.

  • Automotive
