NOT SUITABLE FOR DOHC 3.4L. No way, no way, no way

This product is listed as suitable for the 3.4 liter DOHC engine that found in some Lumina, Cutlass, Supremes and GrandPrix. This will NOT FIT the core hole specified by GM for this engine. The heating element is irregularly shaped to clean the center cylinder. Zerostart #3100015 fits very well.[.]

Pros
  • The most efficient and reliable way to preheat the engine block
Cons
  • I don't remember but there was something

I wanted to install in a car service, but.

Was going to install it at a car service but they said it wouldn't work. I personally don't think they even tried as it was still in the box with no lube or oil and I wasn't charged for the freeze plug. I would have thought they would have to install a new plug after removing the one that fits this heater. I give it 4 stars because I don't know if it works or not. If I ever try to install it myself or someone else I will rate it differently.

Pros
  • Works by dipping it directly in the coolant and heating the block
Cons
  • Not bad but...

Works on an old S-10 truck with a 2.8 liter engine

I installed this on my 1986 GMC S15 pickup - same as the Chevy S10 pickup - with a 2.8 liter V6 engine. It goes near where the smoke pump should be, under the generator, and I believe the spec should say 9 o'clock. The place is easy to get to with that motor, but if you have a crosscar it will probably be a different story. I was patient and didn't turn it on until I started a cold engine and let it run for 15 minutes to make sure all the bubbles were gone. The freeze plug wasn't too difficult…

Pros
  • Application varies by part number
Cons
  • Some cons
