@djBADUY,

As far as I know interchangeable yung head ng RF at R2, in fact yung part number nyan sa ibang supplier e pareho.

Kung tama ang intindi ko, 2005 pa nailagay yung RF head dyan sa R2 nyo but you only noticed overheating lately nung binuhay mo uli yung AC ng pick up.

Important notes and questions:

1. Yung ibang linya ng radiator nyo eh patay na, condemned because of leaks.

2. Yung cooling fan eh napalitan na rin, ano po ang ipinalit brand new ba, mechanical type ba or clutch type.

3. Naglagay din ng auxillary fan, brand new rin ba at pahigop ang air flow.

4. Yung water pump nyo napa-check nyo na ba, eto kasi ang isa sa mga identified na usual cause ng overheating ng RF at R2 engines leading to cylinder head problems.

5. Gumagamit ba kayo ng coolant, kasi baka puno na ng sediments yung water pasages ng cooling system nyo. Diba kayo natutuyuan ng tubig.

6. Yung 508 sanden pang double AC set up na yan gaya sa mga van pero kaya ng R2.

7. Ano po yung low at high side pressures ng AC system nyo.

8. Yung idle-up ba ng AC ay gumagana.

9. Me Thermostat (valve) pa ba yang makina nyo, di kaya yan stucked-up at ano ang temperature rating nyan.

10. Well-tuned ba yung engine nyo.

Kung ako, ang uunahin ko e ipalinis yung cooling system at palitan yung water pump. Yung radiator, ang huling tanong ko for Evercool e P6500 yata, (mabuti rin kung mapalitan na ito).

Kung hindi tama yang Head ng makina nyo, dapat matagal ng nagluko yan.

Yung diesel engines nag-ooverheat yan dahil sa overfueling (pero dapat makapal at maitim din yung usok), excessive loads, at inefficient cooling system. Hindi eto nag-oover heat because of lean burn gaya sa gasoline engines. Actually always lean burn ang diesel engine relative to lambda point ng air/fuel ratio. Pag may problema sa timing at valves ng diesel engine e malamang abnormal din ang usok nito.

Makikita din naman ng mekaniko kung hindi match yung water holes ng head at engine block bago ito isalpak. Good luck po.

clutch fan na po yung pinalit...orig na.tapos po yung auxillary ay sanden.sa may bumper nilagay.lakas naman po ng higop nya.sabi ng mechanic ko ok naman daw po yung pump.pero padouble check ko din po today.tapos yung sa thermostat,patingnan ko n din today.tingin ko hindi nagana yung idle up kasi nababa po yung rpm kapag naka-on yung ac.pano po tinitingnan ung pressure ng ac?saka since po pinaoverhaul ung radiator,lagi po distilled water na gamit ko.kaya galit si misis lagi nababawasan ang tubig ni baby.hehe
maraming salamat po sa patience ninyo.update ko po kayo sa results.may peace of mind na ko ngayon na interchangable yung dalawa.sensya na po sa typing..always in a hurry,babysitter din ako ngaun eh.
ingat po tayo lahat sa bagyo...

[djBADUY]

pahabol:
yun po tune ng engine ok naman po.wala usok at lakas ng hatak.kahit naka -AC.basta moving siya.in fact,saglit lang po ko sa smog noong nagperenew ako.isang rev lang.hindi pa naman po siya natutuyuan nang tubig since overhaul...kapag po tumaas temp,patay na ac.
salamat po ulit.
ingat po tayo lahat.
GODBLESS.

Yung fan shroud nyo pala buo pa rin ba, how many blades yung fan, orig rin ba, bago ba yung fan clutch o surplus lang.

Mas mabuti kung gagamit kayo ng glycol coolant o antirust additive man lang para maiwasan ang corrosion at scaling ng cooling system.

Yung RF at R2 parehong 86 mm ang bore diameter, 86 mm at 94 mm respectively yung bore length nila.

Dear Redvegetarian:

What happened na to your smoker? Have you determined the cause of the smoke yet?

Contaminated fuel tends to stop the motor rather than cause it to smoke.

You should perform the plate test to make sure what the engine is spewing out.

Remember oil will condense, diesel fuel will probably not.

Dear djBaduy:

Long term overheating is not good for your engine (or your wallet).

Cooling systems are very straightforward.

1) There's the engine and its water passages - which should be clean.

Try looking for a shop with the Lav'ramon machine, they do a decent job of cleaning the engine.

2) Check you radiator hoses and water pump for leaks.

If there's any question about the hoses, replace them. The thing to look for in the water pump is the mechanical seal - if its damaged the pump will leak water.

3) The radiator should be clean and in order.

Your radiator should be free of blockage inside and out. Blocked off passages are unacceptable - replace the radiator if this happens.

A good radiator repair shop in QC is Keyser along West Ave.

4) Always use distilled water for the radiator.

Report to use what happened.

Good luck

Hi mga sir!

It been a a few days since I logged in. Let me update new on what happened with my smoky engine. I had the injectors replaced and the injection pump calibrated. It turned out to be faulty injectors, its injecting too much diesel into the engine. Medyo masakit sa bulsa. Pero sa wakas ok na siya tumakbo ngayon. Wala na usok at pinong pino na ang takbo ng makina. Yung actuator na lang ang kulang at wheel alignment. Thanks sa lahat ng advise especially kay youngrider at sir dusky

Dear Redvegetarian:

Nice to hear from you again. At least we have some good news from you now.

So over-delivery ang naging problema.... hmmm, usually simple over-delivery results in BLACK smoke and not white, especially if your nozzles are leaky.

Try going to 2nd-hand dealers who strip engines - like Giant in Banawe - they may have a suitable vacuum-actuated, fast-idle device.

My advice to you is to get your wheel-alignment right 1st, because mauubos ang gulong mo ka-agad kung pinatagal mo - the fast idle device can wait.

EB anyone?

Dear Guys:

As I said before I'm game to meet, medyo lang dapat malapit sa QC as GRABE na ang TRAFFIC. Also, better if its scheduled on a weekend (preferably Sunday).
