Dorman, Murray, or Mahle?

[pjstar35]

My thermostat housing is leaking so I'm currently shopping for a replacement but have a dilemma. There's a Dorman for $71 and a Murray for $65 but both only have a 1 year warranty. Then there's a Mahle brand housing for only $58 that has a lifetime warranty. It seems like the cheaper option with a lifetime warranty would be the way to go but I don't know anything about the quality of Mahle products. Does it have a lifetime warranty as opposed to the others because it's likely to go out again? Presumably the one on the car now is original and the car has 65k miles on it. Is it safe to assume that a new one will last another 65k miles? I'm just unsure which one to go with. Any thoughts on any of this including the quality of Mahle products would be appreciated.

I am an automotive wholesale supplier- Mahle makes very dependable parts at a good price. Dorman is just the name brand the aftermarket recognizes. I've never heard of Murray in my 9 years in the trade.
I'd go for the Mahle.

can't go wrong with Mahle as stated above, i have alot of experience with engine parts, pistons, gaskets (also victor reinz which was part of DANA corp which Mahle acquired in 2007 ish) and so on, always thought was very high quality.. and never once did i have an issue.. and when i rebuilt my jeep engine (original piston skirt failure) i was impressed recently that the quality of the gaskets and parts didnt drop after mahle aquired dana/victor
reinz ..


dorman, is known for budget aftermarket parts.. sometimes good parts sometimes bad... or onpar..

Murray ? didnt know snowblower/lawnmower company made car parts...

I say Dorman as they engineered theirs to fix the Pcv issues that fail on all intake manifolds. So no need to do a PCV bypass / fix. Plus it's cheap.

its just a bandaid to the inevitable.. last longer probably, but when it get caked in crap causes blowby, and or seals shut and rips apart your still in the same boat... atleast bypass kit V2 is easy to take apart and clean out reinstall the check valve.. which is what i had installed.. but again i didnt wait till it failed..

in all this time your telling me NO OEM style aftermarket can design something to put a typical PCV valve or check valve or some crap except put my finger here and hold the damn thing in place. intake has room, or make it plug or screw in the the journey or what not... argh.. 7 years and best we got is racerx intake to add bypass kit..

At the very least, Dorman does seem to be trying to improve on some parts. I'm using one of their coolant tanks now having had 2 OEM ones that cracked and ruptured.
