What is a type 4 jdm engine? I am no forum master but can we ask that you add a signature so we get more info then just in your short description.

I have had similar problems when I went from an F22 Accord motor to a H22 now H23 DOHC vtec motor still using the Accord radiator. Fact is Hondas cool well if the system is running right but I found two main problems after 2 years of frustration with mine before I rebuilt it.

1. It needed a head gasket, see item A. for H22A motors at least.

2. The guys who did the swap put the top hose OVER the a/c lines instead of under, it was badly squeezed flat over a full 180 degree bend, little did I know how important good flow was to an already terrible head gasket.

A. Head gasket, if told anything to every prelude or hybrid H22A cars with the H22A DOHC VTEC motor I would say replace the head gasket with a high performance thick race gasket.

Side note it will also burn oil for ever in vtec rpms just deal with it.

Re: radiator problem in hybrid

Did you refill w/correct coolant mix ? Is your thermostat reinstalled correctly, and working ? Your radiator hoses routed (and not kinked) properly ? Your water pump working ? Is your electric fan cycling on ? How many times you overheated it ? Your engine is at risk. What do you mean by the 'radiator overheated' ? Is a temperature gage telling you that its running too hot or what... ?
If you open 'er up hot (remove thte radiator cap), it'll indeed blow like a geyser (all over, including your face, etc, its not fun...) but this is not necessarily an 'overheat' condition but the fact the system is under pressure and temperature...
How long (operation time and conditions) untill it 'overheats' ?
Peace,
Z
