So I'm having serious cold start issues with my Lude. Has a Euro-R H22 swap with Pro1 cams. It was a pain in the ass before but after holding the throttle for a bit it would stay running. It's been getting really cold out here in NY and I cant get it to start in the morning at all now. Won't start unless I depress the throttle and hold it. As soon as I let off, it stalls. And it runs super rich. I just driver off and it's fine once it warms up. I also have the throttle plate stop screw adjusted to hold the plate open a bit. I'm pretty sure a block heater would help with it warming up in the morning. Now I've been trying to find info on a block heater and I know Honda made one that is now discontinued. I found this one on eBay:

http://www.ebay.com/itm/Zerostart-T...its=Model:Prelude&hash=item3cda17dbe3&vxp=mtr

Is it compatible with the H22A? Is it any good? Any input on block heaters in general?

Youcan buy block heaters up in canada, they are around 60 bucks and the cord is another twenty.

Simple as asking a canadian luder to go to dealership and buy you one and mail it to you..... Easy peezy

Sounds like a lot of work. Haha!

But seriously, the one in the picture looks very similar to the pictures I've seen of the OEM ones.

Don't go putting a bandaid on the issue. You're obviously having rough start issues and a block heater isn't your solution. One of the idle or throttle control valves is having problems because it definitely sounds coolant related if your problems go away once the coolant is warm. From that understanding it sounds like the FITV is faulty since that controls air flow at cold start and slowly reduces it as the coolant warms up. Try performing the troubleshooting from the Helms for rough or cold start conditions and see where that gets you.

As for the block heater you need to make sure the thread is exactly the same as the block bolt it replaces. Its not enough that they just look the same.

I bought the last three USDM ones from Honda three years ago (the same part# is used for ALL 92-01 Preludes). I used one on my 2000SH, one on my 2000 Civic EX, and one left over for my H22 build. I also bought one for a 98 Accord (slightly different part#), and it is the same heating element, just the power cable length is different. Still available from Honda for $60 Part# 08T44-SV4-100.

The ebay one mentioned above looks exactly the same as the Honda part. The block heater goes where the #32 bolt is in this parts exploded view (part# 90001-PM3-003 which is used on many Honda engines)

What is bolt #32? Looks like it's near the oil pressure switch. I'll answer my own question...looks like drain plug.

Will this thread properly sine it's an Accord...I know at work on the Lexus vehicles most drain plugs are 14mm plug bolt head. Even though the bolt heads are same size does it mean the threading is same? I'd rather get the engine heater that's made for the Prelude.

Yes the thread is the same - did you not read my previous post that you quoted?

I used a Prelude one in a Civic (D16Y8 ). The 92-01 Prelude includes F22, H22, H23. The Accord F23 also uses the same drain bolt 90001-PM3-003. I can guarantee you that the only difference between the different part#s is the cable length because the heating elements are all the same. You will need a 24MM socket to install the heating element and torque is 44FTLB.

Here is a list of vehicles using the same drain bolt 90001-PM3-003 (you install the heating element into the block where this drain bolt was)

Make sure to apply RTV gray to the threads when installing. All drain plugs on the back of the block are supposed to be installed with RTV gray, including the heater even though the instructions probably do not specify.

The thing was a bitch to install. I drained the coolant from the rad and then when I popped the freeze plug loose, I was drenched in coolant. But it helped my issue a great ammount. The thing was definitely worth it.

the drain on the rad only drains the radiator, not the coolant form the block, to do that you need to either pull the block heater or the plug that goes where the block heater is.

Yup. That's what I did. And I couldn't get that bolt off in any other position, so when I got it loose, i was in the prime position to have a face full of coolant :-x
